TerraShape.
TerraShape is a new utility.
It is basically a translator for shapefiles->dxf files->shapefiles.
This enables easier editing without the need for a high-end GIS package.
You can download the manual in pdf v5 format here TerraShape Manual (3,0mb)
or download the program with manual included here TerraShape v1.1 (4.6mb)
Just unzip the archive and run the installer to install TerraShape.
The manual has been updated and the images should be better quality (hence the much larger file size).
Please also read the readme file for late information.
Here is a new build (1.4.8.22). This new build adds the DEM and Contouring functions.
Just put the new .exe into your TerraShape directory. TerraShape v1.4.8.22b
Please read the readme file contained in the zip.
