Open Source Geospatial Foundation

The Open Source Geospatial Foundation has been created to support and build the highest-quality open source geospatial software. The foundation's goal is to encourage the use and collaborative development of community-led projects. This website serves as a portal for users and developers to share their ideas and contribute to project development. As the Open Source Geospatial Foundation grows and changes, so will this website. Please check back often and sign up to the mailing lists to monitor developments. To get involved, check out the Getting Started page.

International Systemap Corp.

This B.C. based company is a developer of digital photogrammetric and orthophoto mapping systems.

PurVIEW converts Arc- desktops into precise stereo-viewing and accurate Virtual-Z 3D feature digitizing environment. The well-proven technology exploits geo-referenced aerial or space-borne imagery and DEM, standard data staples for orthophoto processing—also used in ESRI Image Server .

Orthophotos are uniform-scale map-like rectified imagery. Unfortunately, apparent tall feature leans—due to uncorrected object forms rarely modeled in a DEM—cause horizontal positional shifts for the tops…and lee-side occlusion for the base and adjacent features, hampering feature digitizing especially in urban and forestry applications.

PurVIEW eliminates this handicap as not only relief, but also tall objects all appear upright. Even feature occlusion in extreme cases can be overcomeby Virtual-Z digitizing the unaffected primary image.

Manifold System GIS

A U.S. based company, publishes Manifold® System, add-ins for Microsoft's Access® data base, data sets, utilities and other data visualization and analysis software, including user friendly GIS software. Manifold is a relatively inexpensive GIS option.
