Data Formats: GDF

The package format.gdf is part of the LuciadLightspeed Graph and Routing Engine component, and allows you to access GDF (Geographic Data Files) data. This developer's guide gives a short introduction to the GDF format, and explains how to incorporate it in your LuciadLightspeed applications using the format.gdf package.

With the GDF functionality, you can:

Decode GDF files and import them into a LuciadLightspeed-compatible GDF model
Visualize GDF models using standard LuciadLightspeed tools
Generate multileveled/tiled copies of models
Encode GDF models into GDF files.
