Data DisseminationWith the faithful evolution of applications away from the desktop and onto the internet, the need for web-based data distribution mechanisms has become paramount. Web-enabled mobile devices such as the iPhone and the PSP are proving everyday the public's need for timely, remotely-served data.
In the geospatial arena, mobile GIS and field mapping devices are revolutionizing the way data is collected and conveyed. Free, internet-based applications such as Google Maps, Microsoft Live, and OpenLayers have drastically increased the audience for geospatial data. Even traditionally desktop-bound GIS applications such as ESRI's ArcGIS are now embracing distributed data sources.
Data Dissemination Experience:
- Geospatial Onestop-compliant GIS data clearinghouses and portal creation
- Service oriented GIS data dissemination including WFS and WMS services
- Web-based spatially-encoded standards including GeoRSS, GeoJSON, WMS, WFS
- Distributed server architecture
This newfound need for distributed data has engendered several exciting changes within the GIS field including:
- Increasing standardization and interoperability of gospatial data through XML-based encodings including KML and GML
- The growing importance of Internet-based GIS data clearinghouses including Geospatial Onestop (GOS) , the GLIN GIS, and RAMONA
- The increasing convergence of spatial and aspatial data (RSS -> GeoRSS, JSON -> GeoJSON).
- The maturation of enterprise GIS to share across an organization
