FOCUS ON:
Renewed GeoConnections
The 2010 Federal Budget announced renewed funding for the GeoConnections program. The Budget provides $11 million in funding over the next two years to continue development of the Canadian Geospatial Data Infrastructure (CGDI) and to provide consolidated geographic-related information to Canadians via the Internet.

Validating Web Feature Server for Open GIS Spatial Data Infrastructures
This project has two main goals. The first is to enhance GeoServer, which is free, open-source server software that allows users to access geographic information over the web. The project will extend GeoServer into a validating Web Feature Server by giving it read-write access to data in several standard geospatial databases. "Read-write" access means that users can not only read the data but also "write" it-edit or manipulate it on-line.
The project's second goal is to provide a mechanism for checking, or validating, on-line edits to geospatial databases to make sure the edits are clean and error-free. Once users can edit geospatial data, there is a risk that they may accidentally submit invalid changes, which can gradually corrupt the database. Invalid changes can range from spelling mistakes and incorrect codes to geospatial errors like segments that are not connected. These errors, which may at times appear insignificant, can make the final product analytically unusable. The validating Web Feature Server (GeoServer) developed under this project will not only validate but also possibly repair edited features before they are accepted into a geospatial database.
With these two developments, the project will make the free GeoServer system more attractive to users within the Canadian Geospatial Data Infrastructure (CGDI). Users of GeoServer will gain greater access to and support for several common geospatial databases, without affecting their budgets. They will also be able to update, query, delete and create data, then validate their changes. These are particularly welcome abilities for complex on-line systems such as national road networks. Such systems need to be open, so that they can be quickly and easily updated, but they also have strict requirements for data validity and integrity. The British Columbia Ministry of Sustainable Resource Management, a project partner, will benefit from the new capabilities as it moves to geospatial databases that allow for third-party updating. The project will also help the Ministry share provincial data within the CGDI.
