Web Mapping Testbed, Phase 2

The Web Mapping Testbed Phase 2 (WMT-2) expanded on work done in WMT-1. It resulted in more federal data coming on-line using WMT protocols and laid a foundation for OGC Pilot Projects that tested and demonstrated the new capabilities. WMT-2 resulted in improvements to GetFeatureInfo, GetMap, and GetCapabilities, the basic elements of the Web Map Server Interface Specification. It also resulted in a proposed service interface specification for accepting multi-dimensional query requests and responding with portrayals (symbolized graphics) of the results (with associated legends).

Simple Features SWG


Herring, John (Oracle USA)
Scarponcini, Paul (Bentley Systems, Inc.)

Group Description:


1.    ISO Simple Features

A Standard working group is being formed to work on the ISO version of the Simple Features specification. The intent is to create a fully harmonized standard so that the OGC and ISO standards and the SQL/MM Part 3 spatial versions are harmonized at the end of the work of the  SWG. A summary SWG description is given here and expanded below:

GeoSPARQL - A Geographic Query Language for RDF Data

The OGC GeoSPARQL standard supports representing and querying geospatial data on the Semantic Web. GeoSPARQL defines a vocabulary for representing geospatial data in RDF, and it defines an extension to the SPARQL query language for processing geospatial data. In addition, GeoSPARQL is designed to accommodate systems based on qualitative spatial reasoning and systems based on quantitative spatial computations.

USGS Interoperability Assessment

The rigorous testing of USGS web services performed in the Interoperability Assessment Project helped us identify and correct shortcomings of our implementation of OGC standards, and highlighted areas in which to improve the user experience with our web services.  As a result of the project, our users can include the improved USGS services more easily in their decisions making and operational activities.
