Notes:
Today, Tiffany provided a demonstration of UV CVAT, and described ClimatyePipes, two visualization analytics tools. Tiffany followed with a continuation of last month's discussion on different types of data analytics. Steve followed, showing the ESDA Use Case Gathering website, and Data Analytics Tools/Techniques Inventory website.
From Tiffany's UV CVAT and ClimatePipes demonstration/discussion
UV-CDAT http://uv-cdat.llnl.gov/ Description: UV-CDAT brings together two active projects -- Ultrascale Visualization Climate Data Analysis Tools and Visual Data Exploration and Analysis of Ultra-large Climate Data, with the intent to deliver new capabilities to the climate-science community. This project’s vision is to provide large-scale visualization and analysis for both observational and model-generated climate data, with the goal of delivering new capabilities into the hands of the climate scientists. The integrated software product, the Ultrascale Visualization Climate Data Analysis Tools (UV-CDAT), is intended to be a powerful and complete front-end to a rich set of visual-data exploration and analysis capabilities well suited for climate-data analysis problems. UV-CDAT builds on the following key technologies: the Climate Data Analysis Tools (CDAT) framework; ParaView; VisTrails; and VisIt.
Additional Info: The NCCS at GSFC is developing climate data analysis and viasualization tools for UV-CDAT, that provide data analysis capabilities for the Earth System Grid (ESG). These tools feature workflow interfaces, interactive 3D data exploration, hyper wall and stereo visualization, automated provenance generation, parallel task execution, and streaming data parallel pipelines. NASA’s DV3D is a UV-CDAT package that enables exploratory analysis of diverse and rich data sets from various sources including the Earth System Grid Federation (ESGF). Additionally, Python scripts can easily be generated.
ClimatePipes Description: ClimatePipes is a web-based application platform/"IDE" for science data analysis. It can be used to create and run analysis workflows and visualizations. Additional Info:The front-end uses HTML5, WebGL, and CSS3 for geospatial visualizations. The back-end is built using the Visualization Toolkit (VTK), Climate Data Analysis Tools (CDAT), and other climate and geospatial data processing tools such as GDAL and PROJ4. ParaView Web, and D3, Canvas are also used for some visualizations, offers look-up tools, works with UVC-DAT and MongoDB. It can read NetCDF, offers a python Web Service infrastructure, supports workflows and provenance tools using VisTrails. Python was chosen as theserver-side language using CherryPy (http://www.cherrypy.org/) as the web server. JQuery (http://jquery.com/) and Bootstrap are being used as the supporting frameworksfor a consistent interactive cross-browser experience.
Tiffany next continued discussion to answer the following questions:
1. What are your most time consuming data tasks that can leverage analytics?
2. Identify and discuss different types of analytics
3. What kind of data analytics is needed for specific use cases?
4. Identify tools and technologies that address different types of analytics
Discussion focused on the different types of data analytics:
In particular, question 3, regarding use cases, and question 4, regarding tools and technologies, led to a 'tour', by Steve, through the ESDA information gathering pages. Namely:
Use Case Collection webpage - http://wiki.esipfed.org/index.php/Use_Case_Collection
Data Analytics Tools/Techniques Collection webpage - http://wiki.esipfed.org/index.php/Analytics_Tools
In the spirit of compiling use cases, analytics tools/techniques, and performing gap analysis between use case analytics needs and available tools/techniques, telecon participants volunteered to provide data analytics use cases. This is as simple as providing the following information:
Use Case Name: Provided By: Brief Description: Key Analytics Needs:
ESDA members are all encouraged to provide use cases they may have come across or are faced with. Thanks Beth, Robert, Suhung
The 'tour' continued with a walk through the Data Analytics Tools/Techniques Collection webpage. Upon soliciting for additional analytics tools/techniques, Tiffany offered a list that she has been compiling. Other are encouraged to share, as well.
You can edit the websites, or if easier, feel free to send use cases and tools to: Steven.J.Kempler @nasa,gov.
Additional Discussion:
- Preparation for using specific analytics tools may be difficult, or not possible, if the tool can not support specific data characteristics. Beth discussed the ESIP Semantic Web Cluster, ToolMatch project, for us to track tools for data analytics:
ToolMatch Service (http://wiki.esipfed.org/index.php/ToolMatch): Finding Tools for Your Data & Data for Your Tools, ToolMatch is intended to be a service based on community-built semantic web applications that will provide data users with the means to match their datasets with a comprehensive list of useful, appropriate tools, and also provide data tool developers with datasets or data collections that will work with their tools.
Next ToolMatch telecon: Tuesday May 27 at 4pm Eastern time
Call-in toll-free number (US/Canada): 1-877-668-4493, code: 231 033 48
WebEx: https://esipfed.webex.com/esipfed/j.php?MTID=m98ad38879252b9000f6a489a8b2fad48, If a password is required, enter the Meeting Password: 23103348
- Exemplary Use Cases: Looking for correlations across multiple variables; Bringing multiple datasets together utilizing Giovanni
- Add use case column to tools inventory matrix to indicate who would find tools useful (i.e., data producer, user, etc.)
Preparations for ESIP ESDA Breakout Meeting in Frisco (30 min)– Steve
Potential topics for ESIP ESDA cluster meeting (not ordered)
1. Data Analytics tools matrix – Gleaning out what tools can provide
2. Use case Matrix Analysis – Gleaning out Data Analytics needs
3. Summary of past speakers – Gleaning out highlights: Data Analytics needs and/or tools and their targets
