Layer

Each layer in a TerraBuilder project references a particular data source that is stored in:

§  Files on your own computer or on your local network

§  A remote database that is served over a network

Imagery layers contain geo-referenced, satellite or aerial images that overlay the terrain imagery whereas elevation layers contain geo-referenced elevation rasters that replace the elevation data of the terrain database. You work with the layers in your project, clipping, resizing, moving and recoloring layers, as required, to create a photo-realistic, geographically accurate database.

Layer modifications do not affect the source files they reference. If TerraBuilder does not have access to a source because it or its directory was moved or renamed, the layer based on this source does not display in the Layer windows and it is excluded from the MPT or TBP file that is created.
