TermDescriptionTags
AQ Community CatalogThe AQ Community Catalog is theAQInfrastructure
Coverage Processor for PointsThis component reads a subset of Station Point Data out of an SQL database. It gets the requested coverage from the query and gets the relevant SQL table and column names from the configuration information. Then it creates an SQL query according to filters, which is executed in the SQL database engine, and the resulting rows are written to a CSV file. Used in WCS GetCoverage Query.WCS
Datafed BrowserDatafed Browser is a web program for viewing WCS and WMS services.WCS
AQInfrastructure
GEOSS ClearinghouseThe GEOSS Clearinghouse is the engine that drives the entire system. It connects directly to the various GEOSS components and services, collects and searches their information and distributes data and services. The AQ Community records can be found in the clearinghouse and aq applications, like uFIND, search the clearinghouse.WCS
AQInfrastructure
Google EarthGoogle Earth lets you fly anywhere on Earth to view satellite imagery, maps, terrain, 3D buildings, from galaxies in outer space to the canyons of the ocean. You can explore rich geographical content, save your toured places, and share with others.WCS
ISO 19115 Metadata for Air QualityISO 19115 is the metadata standard for Geographic information. The AQ Community chose ISO 19115 because it is a standard accepted by GEOSS and being implemented widely around the world. It includes the ISO 19115 Core, 19119 metadata for describing the geospatial services and AQ-specific metadata for finding datasets.WCS

KML Keyhole Markup LanguageKML is a file format used to display geographic data in an Earth browser such as Google Earth, Google Maps, and Google Maps for mobile. KML uses a tag-based structure with nested elements and attributes and is based on the XML standard. All tags are case-sensitive and must be appear exactly as they are listed in the KML Reference. The Reference indicates which tags are optional. Within a given element, tags must appear in the order shown in the Reference.WCS
Python DictionariesPython is a simple programming language. It contains the dictionary datatype, which is a simple key=value hierarchical database. Due to simple syntax, the datafed WCS uses it as a configuration file, instead of xml files or something similar.WCS
