Discussion of what is needed from community to enable semantic and syntactic interoperability

Sensor manufacturer responsible for making OEM model description
creates a unique identifier for each sensor
SensorML file is created and belongs to sensor owner
Data managers describe processing that's done
Documents reference terms that have meaning --> reference ontologies
Hoping to get community to help with development of ontologies, esp in communities Janet isn't a part of (i.e. not in oceanography comm'ty) -- then Janet can work with sensor manufacturers to reference those terms
Recorded presentation includes example ontology form; Wiki reference links should include date accessed
MMI ontology registry has a big vocabulary database
Can create new vocabularies and map to other known ontologies
Watch the video of the telecon for more information about how this works

Scheduling an informal lunch/coffee meeting at AGU in San Francisco (all)

Scotty added Janet's presentation schedule to his schedule for the meeting -- contact either of them if you want to meet up with them
Janet will send out this message to everyone

Next meeting (2/6/17)

Vasu and Janet talk about engaging sensor manufacturers

Change in leadership

Scotty Strachan to begin co-leading EnviroSensing group with Janet Fredericks
good time to change leadership, Don is retiring soon, time to think about new directions (XDOMES? other projects?)
Matt Bartos (U Michigan) will take over as student fellow (Alison is done at the end of the year)

Discussion of new directions

Don - short recap of history of EnviroSensing cluster and original mission
this is review from previous telecons--see past notes
Janet - update on past year of work on XDOMES
ES group mission and goals is well-aligned with her work, but she needs people to participate rather than just be an audience for the work they're doing
e.g. looking for vocabularies... need this before can go to sensor manufacturers
having difficulty getting people involved -- need folks to participate!
no ES explicit presence (i.e. no specific sessions) at winter meeting, but intend to have a session at summer meeting
Don suggested more explicitly crafting this as a clear opportunity/desire to get people involved
good to tie to specific time frame, task, or event
Send out info prior to telecon, have people look at it and prep something specific, then discuss on telecon
maybe try to target specific people - perhaps folks can help ID who these people would be
follow-up meeting next month to try to get volunteers to describe sensors (spreadsheet?)
plan to have an informal ESIP/EnviroSensing get-together at AGU?
would be great to have a few volunteers, work up to people doing talks at ESIP Summer Meeting?
spend some time together talking about what this is, catching up on the cluster, etc.
Scotty - some thoughts on future directions
excited to step in and help out with the group, since it's been very helpful to expand his data management world
completed PhD over the summer, things are currently a little hectic--transitions, etc.
focus on field designs, esp. on mountain environments
could do multiple projects at once--would be good to stay focused and help the XDOMES project

Janet Fredericks on Q2O web service
Using SWE to bind metadata to observational data - enabling dynamic data quality assessment
Background: NOAA-sponsored project to address data quality in sensor web enablement frameworks

Janet walked participants through the Q2O (QARTOD-to-OGC) web service implementation to demonstrate how web services are used to describe processing, select and describe data and offer it to a user as a service.


open sensor access so that people can discover sensor data, etc.
geolocatable/geospatially aware, fully described data, sensors, and processing
free open source software on github

SmartCity Air Challenge

Ethan: EPA is putting out a challenge called the SmartCityAir challenge: ask communities to tell them how they would deploy a large team of air sensors
provide seed money, etc.
groups have to describe how they would monitor and manage the data, deal with sensors throughout their lifecycle, do this sustainably…
gov’t learning what practices work best
will be announced formally next week; Ethan will send a less formal paragraph out to this group
interested in ideas for how to get word out about this, how to encourage people to use best data management practices that exist
focus is really on the data management side

With XDOMES and OpenSensorHub → trying to get all of that kind of knowledge (how it was used, description of data, etc.) so that you could have people throwing sensors out and have access to that data

Summer meeting:

Janet will be sending out an email about preparing for the workshop at the summer meeting → people can let Janet know that they’re coming
At Thursday session hopefully Janet, Mike, and Vasu will all be presenting
Maybe talk about whether we want to reach out to a broader audience? Janet would like to know how many people plan to attend the workshop
Poster? Don says we did one last year and could just substitute some of the stuff on there with summary points of what we’ve done this year on our calls -- Don will produce the poster if Janet sends summary slides from some of the talks to him

NO call in July -- we’ll just see each other at ESIP! Next call will be in August.

Mark Bushnell – Quality Assurance and Quality Control of Real-Time Ocean Data (QARTOD):

QARTOD manuals: focus on real time, usually coastal (http://www.ioos.noaa.gov/qartod)
Includes quality control tests and quality assurance of sensors (in an appendix)
Discussion of operational vs. scientific quality control and different needs/contexts for each
Board meets quarterly to review progress and identify next variables (if you have ideas for variables, let Mark know!)
Each manual takes 6-8 months and each one is a living document that is updated
26 core variables
next up: phytoplankton species!
Discussed an example test from the waves manual
Five “states” for data qc flags (pass, not evaluated, suspect or of high interest, fail, missing data)

Discussion & Questions for Mark:

How to handle flags that represent a mix of semantic notions? Hard for data consumers to understand (what’s the actual problem?)
What about showing (or not showing) data that doesn’t meet a certain standard?
If you’re looking for extreme events, for example, you might want to see all the data…
Helpful to have the option to see all the data (if you’re an operator, say, you might look at failed tests for an instrument)
Best to let the data user select what level of quality they’re interested in
For EnviroSensing, is there a place to save/share code for QC tests?
Not at the moment
Would be good to start tracking/storing code for tests that people do somewhere and have a DOI that describes the processing
python codes for the implementation of the QARTOD recommendations is at https://github.com/ioos/qartod (also look here --> https://github.com/asascience-open/QARTOD)
Core link in email from Janet (body copied below) -- many other pages and additional information can be found from that link
Background: The U.S. Integrated Ocean Observing System® (IOOS) Quality Assurance/Quality Control of Real-Time Oceanographic Data (QARTOD) project has published nine data quality-control manuals since 2012. The manuals are based on U.S. IOOS-selected parameters (or core variables) that are of high importance to ocean observations. The purpose of the manuals is to establish real-time data quality control (QC) procedures for data collection for core variables, such as water levels, currents, waves, and dissolved nutrients. The QC procedures provide guidance to eleven U.S. IOOS Regional Associations and other ocean observing entities, helping data providers and operators to ensure the most accurate real-time data possible. It began as a grass-roots organization over a decade ago - the background can be found on the IOOS QARTOD Project website: http://www.ioos.noaa.gov/qartod/welcome.html

In those minutes, he has a USGS github link at https://github.com/USGS-R/sensorQC


Attendees (small group):
Don Henshaw
Scotty Strachan
Janet Fredericks


Best practices work:

Post a citation suggestion on the introduction page of best practices? Maybe also a snapshot PDF that folks could download with a citation?
People DO go to this page, says Scotty
Mountain Research Institute (MRI) is doing some work trying to write best practices, would be good to try to get them to use ours rather than create something entirely new…

Future of EnviroSensing cluster:

Just need to have one vision at a time--for now we can stay focused on the XDOMES work
Scotty wants to continue to stay involved, promote cluster and its work a bit more to folks after finishing up his PhD (soon!); would be interested in taking lead in cluster after that, too

Future meetings:

Mark will present material on real-time quality control that was planned for this month on the next call instead, due to low attendance on this call
Would be great to reiterate that we didn’t start as ONLY LTER--the best practices doc had input from other folks too--and that that isn’t where we have to stay, either--we can continue to incorporate other things/groups
Janet will talk about summer meeting workshop plans on June call: registering vocabulary
will be a good workshop for beginners/people who need to be introduced to the concept
Summer meeting (July): have a 1.5-hour session for EnviroSensing--should email asking for folks to present

1. Future meeting ideas (Don)

Revisit best practices--have folks present the chapters they did and rekindle interest; Scotty said he’d be willing to do this for his chapter
Email Alison at [email protected] if you have ideas for future telecons!

2. Summer meeting -- session/workshop ideas? (proposals due at beginning of April)

XDOMES workshop: connected to EnviroSensing cluster?
sensor provenance EnviroSensing breakout session?
Janet to lead more hands-on workshop on Semantic Web, etc.?
Let Alison, Don, or Janet know if you have additional ideas

3. Update on work plan draft (Don & Janet)

Conversation with Erin last week
If you might like to be the next leader, let Don know--thinking of having an “on deck” leader position
Interest in AGU Geospace blog? Lots on data use, etc. This could be a place to put out info about our cluster

4. Rotating chair position for Products & Services (Alison)

Right now, Products & Services does three things: (1) FUNding Friday, (2) the P&S Testbed, and (3) tech evaluation process with NASA AIST to evaluate AIST-funded projects. Also working on an evaluation process for the projects funded through the testbed, and would hopefully provide this to the Earth science community at large eventually.
P&S wants to have a rotating co-chair position; would last for three months and would be a rep from a different committee. The first co-chair (starting in April) wouldn’t be involved in proposal evaluation/selection, but would be involved in ideas for student/PI matchmaking and mentoring for FUNding Friday and the evaluation and testbed activities. It would be a great opportunity to learn more about P&S and have them more about us. It wouldn’t prevent you from submitting a proposal to the testbed.
If you’re interested, email Soren at [email protected]; you can sign up for the rotating co-chair position here

5. XDOMES team on Semantic Web (Krzysztof Janowicz)

Full recording with slides available in recorded meeting
Semantic technologies can improve semantic interoperability
More intelligent metadata, more efficient discovery, use, reproducibility of data; reduce misinterpretation and meet data requirements of journals, etc.
Large community in science, gov’t, industry; many open source and commercial tolls and infrastructures; there are existing ontologies and huge amounts of interlinked data
Move the logic OUT of software and INTO the data
Semantic technologies support horizontal as well as vertical workflows
Semantic interoperability can only be measured after the fact bc meaning is an emergent property of interaction; come up with technologies that prevent data that shouldn’t be combined from being combined
How much of this is already in use or is this just setting up the platform at this point?
With XDOMES we are at an early stage, but in terms of the infrastructure, a lot of it is already productively used

Notes drafted by Alison Adams (EnviroSensing Student Fellow) according to meeting recording

On the agenda:
Janet on XDOMES
What should EnviroSensing cluster do?

XDOMES (Cross-Domain Observational Metadata Environmental Sensing Network) NSF project funded as part of EarthCube

  • cross-domain observational metadata
  • focusing on: sensor metadata creation, data quality assessment, sensor interoperability, automated metadata generation, content management
  • 4 types of work (funded for two years)
    • software development to create Sensor ML Generators and registries for semantic techs and Sensor ML documents
    • Trying to engage people like this community, sensor manufacturers to create a network of people interested in promoting adoption of sensor ML techs
    • Useability assessment
    • Integration of semantic interoperability
  • this project is about capturing metadata at the time of CREATION of the data
  • GOAL: put out metadata automatically in interoperable ways (community-adopted, standards-based framework)
  • use of registered terms to enable interoperability
  • can also help manage operations by providing standardized information about how sensors were configured, etc.
  • want to develop community within ESIP who will follow and promote this approach
    • vet, look at usability assessment, what do you want us to do and is it useful to you?


  • Vasu says this is related to things EPA has been working on--excited to continue the conversation
  • Jane asked about communication with sensor-creators so this can be implemented in new sensors; Janet said that isn’t part of the project at this point
  • Potential application for folks with Alliance for Coastal Technologies--they work on sensor validation and I think it’s a slightly different take, but this is definitely something they could benefit from (like if we start describing our sensors in a way that the information can be harvested)
  • If people are interested you can see what Janet is putting in the file and think about whether this would be helpful or useful or whether she’s missing something; would you be willing to test this in your own environment?
  • Delivering data is kind of beyond the scope of the XDOMES project at this point
  • Vision: info is out on the web, and you have an app to go and harvest the information that you need
  • Do we want to work this pilot project into public presence in this cluster?

Future WebEx ideas

  • Could do a WebEx on how water ML, sensor ML, etc. fit together
  • Janet is approaching Krzysztof Janowicz to discuss sensors and semantics with us on the March call


Today we had Dave Johnson from LiCOR Environmental speak with us about eddy covariance. We had a large group of attendees.

Dave shared with us links to the LiCOR software [1] and a book [2]

  • The problem they are solving is that the data coming in with eddy covariance is high resolution and large, more than 300 million records per year.
  • They were able to put much of the processing and QC logic into the SMART system, which is on the instruments in the field.
  • An eddy covariance system can "see" about 100 x its height above the canopy.
  • We were interested in the possibilities for real-time data qc, and also how the information can be transferred between the instruments in the field (i.e. cell modem, line, etc.)


Today we had William Jeffries from Heat Seek NYC talk to us about his platform for civilian monitoring of home temperatures in apartments using low-cost sensors and wireless mesh networks taking hourly readings.

Attending the call were Fox and Don from Andrews, Josh at UM, Jason in Fairbanks, Becky from Onset, Ryan from UT and Scotty from UNV as well as some listen-in callers.

  • Heat seek NYC has nodes containing up to 1000 low-power, low-cost thermometers which are mapped to custom printed circuit boards. The software stack is Ruby on Rails with a Post-Gres backend.
  • HSNYC focuses on sensor network's ability to affect and effect policy, and so far has seen that the government views sensor networks as a cool solution to a lot of difficult regulatory challenges. They provide reliable information that officials and citizens can use with printable, court-friendly PDF's.
  • Funding is by kickstarter and was started by the NYC Big Apps campaign, a giant Civic Hacking Competition.
  • They have been incorporated as a non profit in NY since 2014
  • First sensors were Twine Sensors off the shelf temperature sensors; not so good

stale data

  • Now they make their own temperature sensors, using a push system instead of a pull system. (if there's a problem with the system just don't get pull out of it.)
  • We asked about LCD and the reason for not implementing is that many tenants aren't actually as interested in the data as the response from the policy makers
  • Some people will abuse the system so they use tamper evident tape and photos of installation to protect ; landlords have financial incentives and there can be intentional lack of repairs
  • Local cache-ing of the sensor occurs; sensors cache at the hub, relay server that sends back
  • There are several levels of caching, and also well as flash memory on the XP radios
  • A key question was is there a long-term storage that is a local cache? We don't have a solution either
  • We had interest in a company called H20degree
  • For QC they do indoor and outdoor temperature comparison, comparing the sensors to one another and to store bought sensors before and after installation...
  • Frequency for radios/caching is hourly waking up point data
  • We are all interested in a low-or-no power source/ transmitter, maybe based on raspberri pi
  • need a high peak power envelope-- transmission needs to deal with being fairly far apart... implementation needs to come online and transmit an awesome signal for a short time and go back to sleep.

Note on Webex recording: I am going to check into the recording- my system claims to have been recording but it is nowhere to be found (Fox)


Rick Susfalk from the Desert Research Institute presented about Acuity Data Portal. Notes from meeting taken by Fox Peterson, please edit as you see fit.

We had in attendance 8 persons.

Acuity Portal System

  • Started in 2006
  • originally VDV data solution
  • improvements to web-interface; sits on top of VDV as Acuity server
  • Acuity is a continuous monitoring of key client-driven data
  • it includes sensors and data logging deployment and maintenance, telemetry, data storage and analysis, automated airing, web portal for data access
  • individualized web presence tailored to client needs
  • not a single tool, but instead integrates commercial, open source, and proprietary hardware and tools
  • customizable project specific descriptions
  • common tools used to provide rapid, cost-effective deployment of individualized portals
  • physical infrastructure is shared amongst smaller clients for cost-saving or it can be segregated for larger clients.
  • access is controlled down to the variable level-- "we can define who gets to see what"-- for example, public can not see some features
  • one view could be "pre-defined graphs" without logging in, but if you want to download the data you must log in at your permissions level



  • customized thresholding and data-freshness
  • trending alerts, for example, know if battery will go bad
  • stochastic and numerical modeling
  • scoring incoming data for QA/QC processing

QA/QC tools

  • web-based GUI
  • users and managers can create, edit, and modify alerts online
  • groups can be created so that you can schedule management and alerts
  • also offers localized redundant alerting
  • two-way communication with the campbell data loggers (cr1000)
  • more about getting the data to the data managers for more in-depth QA/QC than about providing that part of the tooling

Data graphing features

  • Pre-determined graphs for basic users
  • Data selector for more advanced users
  • "we don't know what the users want to see so we give them the tools to do it" (good idea!)
  • anything you can change in Excel you can change in their graphs on the website -



  • relates your parameters to the network and what other sensors are doing
  • current system is getting more flexible
  • metadata is still largely user responsibility

Flight plan - safety tool

  • field personnel are data
  • users put in the travel time for safety
  • buddy system, alerted right before you return, then calls boss etc. Many levels hierarchy


  • Portals that are monitoring things
  • ability for data refreshment
  • colors for indication, ex., data would not be gray if there was lots of new data
  • users can change the settings on the data logger
  • scrolling, scaling, plotting, etc. via interaction with the user
  • can save your own graphs

graphs and alerts

  • many parameters
  • you can save!
  • email, sms, phone
  • default settings for users
  • lots of personnel management tools in this in general
  • cross-station "truly alarm or not" if station1 has a value but station2 has a different one, don't alarm sorts of rules
  • lists/user groups appear to be very important with this tool
  • sensor and triggers: customize one or more parameters that you are bringing into your database

real-time updates on loggers

  • ex. 10 minute data, user comes in and makes a change, the information is saved to the database and then is presented to all other users
  • the person will request a change and say what that change is
  • when there are different levels of connectivity ie. analog phone modems, before the data has the chance to work its way back into the system there is a lot of validation being done



  • extends beyond the vdv, more than 1 .dat file
  • integrate multiple .dat into many tables
  • managed by the data managers at DRI
  • workflow :

logger net --> vdv --> acuity, ok, let's give access to the DM for all these variables, click on it ok now the manager can see it --> generate an excel file with tables for all this metadata --> enter the data into the excel files--> send back to acuity --> injests, runs queries, back to db-- > metadata in bulk, quickly

  • we asked if the system ends before the qa/qc process begins, answer: qa/qc is done at the DRI, near real time QA though

future capability

  • direct the managers to the future data problems
  • manual decision making

Scotty asked about the duration (long and short term) of projects and how affects funding. most is funded by long-term projects; this is why they do the stats and numerical methods in the future

Amber asked about pricing; pricing is by hour to get up, then a price for maintaining the system for the duration of the project 5-10 .dat files, only 8 hours of person time at DRI to make a portal

Wade Sheldon presented the GCE Data Toolbox – a short summary follows:

  • Community-oriented environmental software package
  • Lightweight, portable, file-based data management system implemented in MATLAB
  • generalized technical analysis framework, useful for automatic processing, and it's a good compromise using either programmed-in or file-based operations
  • Generalized tabular data model
  • Metadata, data, robust API, GUI library, support files, MATLAB databases
  • Benefits and costs: platform independent, sharing both code and data seamlessly across the systems, version independent as far as MATLAB goes, and is now "free and open source" software. There is a growing community of users in LTER.

Toolbox data model

  • Data model is meant to be a self-describing environmental data set-- the metadata is associated with the data, create date and edit date and such are maintained, and its lineage.
  • Quality control criteria- can apply custom function or one already in the toolbox
  • Data arrays, corresponding arrays of qualifier flags -- similar to a relational database table but with more associated metadata

Toolbox function library

  • The software library is referred to as a "toolbox"
  • a growing level of analytical functions, transformations, aggregation tools
  • GUI functions to simplify the usage
  • indexing and search support tools, and data harvest management tools
  • Command line API but there is also a large and growing set of graphical form interfaces and you can start the toolbox without even using the command line

Data management framework

  • Data management cycle - designed to help an LTER site do all of its data management tasks
  • Data and metadata can be imported into the framework and a very mature set of predefined import filters exist: csv, space- and tab-delimited and generic parsers. Also, specialized parsers are available for Sea-Bird CTD, sondes, Campbell, Hobo, Schlumberger, OSIL, etc.
  • Live connections i.e. Data Turbine, ClimDB, SQL DB's, access to the MATLAB data toolbox
  • Can import data from NWIS, NOAA, NCDC, etc.
  • Can set evaluation rules, conditions, evaluations, etc.
  • Automated QC on import but can do interactive analysis and revision
  • All steps are automatically documented, so you can generate an anomalies report by variable and date range which lets you communicate more to the users of the data

  • Fox Peterson (Andrews LTER) reported on QA/QC methods they are applying to historic climate records (~13 million data points for each of 6 sites).

The challenge was that most automated approaches still produced too many flagged data that needed to be manually checked. Multiple statistical methods were tested based on long-term historical data. The method they selected was to use a moving window of data from the same hour over 30 days and test for 4 standard deviations in that window; E.g., use all data for 1 pm for days 30 - 60 of the year, compute four standard deviations, and set the range for the midpoint day (45) at the 1pm hour to that range.

  • Josh Cole reported on his system, which is in development and he will be able to share scripts with the group.
  • Brief discussion of displaying results using web tools.
  • Great Basin site discussed the variability in their data, which "has no normal"-- how could we perform qa/qc based on statistics and ranges in this case?
  • Discussion of bringing Wade Sheldon to call next time / usefulness of the toolbox for data managers
  • Discussion of using Pandas package- does anyone have experience, can we get them on?
  • Discussion of the trade off between large data stores, computational strength, and power. Good solutions?
  • ESIP email had some student opportunities which may be of interest
  • Overall, it was considered helpful if people were willing to share scripts. Discussion of a GIT repository for the group, or possibly just use the Wiki.
