Intergraph (GeoMedia Viewer - FREE GIS!)

Intergraph make GIS systems for Windows, including GeoMedia, GeoMedia Web Map (for internet presentation of data) and GeoMedia Viewer.

See their product website:

Intergraph has offered their GeoMedia Viewer as a free GIS viewing tool. This software will allow you to:

  • View GeoTIFF raster files and perform attribute queries
  • Spatially filter your query, saving valuable time in your search
  • Visualize your data by creating thematic maps,complete with a legend that allows you to easily change any symbology parameters, such as colours and patterns
  • Easily manipulate your map with zoom-in, zoom-out capability
  • and Display data in native formats when you connect to GIS data warehouses.

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.
