3. Summary of GIS Technologies
OGC Simple Features Standard – A standard way of addressing feature (vector) geometries.
GDAL / OGR – Open source library to read and write many popular vector and raster formats.
GeoServer – Open source technology to publish to web services (WMS, WFS, etc.)
PostGIS – Geodatabase technology built on PostgreSQL.

5. Demonstrate Interoperability With
Popular file formats such as PostGIS, KML, .e00 files, and other formats enabled by GDAL/OGR.
Web services such as WMS and WFS.
Interoperability means reading and publishing.
An interoperability framework will make it relatively easy to add support for other formats.

6. Currently Supported Data Formats
KML – Supports Vector and Raster Formats. File or Web Server based
GML Simple Features – XML standard returned by most Web Feature Servers
Shapefile – Lowest Common Denominator for most Mapping Applications
PostGIS & SQL Server – Simple Features SQL database (DAFIF)
GeoRSS, S-57, FalconView Points and Drawings, WMS, etc.

7. Building a Common Data Architecture
Using standard interfaces, promote programmatic interoperability
FOSS libraries leverage other development efforts and promotes adherence to standards
Reading and writing open data standards promotes interoperability with other programs
Access the Data though Open Standards based Interfaces
Simple Features COM
Leverage Open Source Libraries
LIBKML / GDAL / OGR
Read Open Standard Data Formats
KML / WFS / SF-SQL

8. Interfaces IFvDataSource
Provides a single way to retrieve geospatial data from various data sources
Serves features using OGC’s Simple Features COM Standard
Allows access to FalconView Data
Drawing Files, (Local) Points, Possibly DAFIF or Tactical Graphics

11. Libraries
GDAL / OGR – OGR is a Open Source C++ Library for reading a variety of vector data formants and serving them out as Simple Features Geometry
LibKML - Google's C++ library for use with applications that want to parse, generate and operate on KML. It is an implementation of the OGC KML 2.2 standard.

13. Drawing Styles Using Styled Layer Descriptors
“A Styled Layer Descriptor (SLD) is an XML schema specified by the Open Geospatial Consortium (OGC) for describing the appearance of map layers. It is capable of describing the rendering of vector and raster data. A typical use of SLDs is to instruct a Web Map Service (WMS) of how to render a specific layer.” - Wikipedia
