Required Databases

Topographical databases (digital elevation model or DEM) are required for the prediction of propagation.

Topographical databases consist of binary stored pixel data with an arbitrary resolution, for example, 50m x 50 m.
Note: The resolution must be constant per database.

Additionally, morphological data can be considered by empirical correction values to improve the accuracy of the model. This data is also stored as binary data. The different morphological properties are coded, for example:

  • 1 for urban
  • 2 for suburban
  • 3 for forest
  • 4 for waters
  • 5 for acre
