If you can handle data management, TdhGIS can handle spatial analysis

 

With TdhGIS, you can:

  • Create thiessen and buffer polygons from points.

  • Allocate point data to polygons.

  • Allocate polygon data to other polygons.

  • Color polygons based on user data using either discrete intervals or gradients.

  • Create contour lines and polygons.

  • Intersect, merge, and subtract sets of polygons.

  • Determine the area and perimeter of polygons, including exclusion polygons (i.e. holes).

  • Import and export shape files.

 

With TdhGISnet, you can:

  • Perform shortest path analysis for any number of intermediate destinations.

  • Import OpenStreetMap data by specifying way tags (e.g. select roads, walkways, rails or any other way data in OSM).

  • Add nodes anywhere, permanently or temporarily, by clicking or specifying coordinates.

  • Edit data, display results graphically and produce reports usable within spreadsheets or database managers.

 

With either program, you can:

  • Use raster images as background.

  • Transform coordinates based on the Proj4 library. (e.g. convert from longitude-latitude to cartesian coordinates.

 

TdhGIS and TdhGISnet are free software, run on Linux and MS Windows and can be downloaded at TdhGIS.com
