From XCSoar
The topology file (extension .tpl) is a text file containing a series of entries each of which define a layer of topology. Typical layers include roads, railway lines, large built-up areas (cities), miscellaneous populated areas (towns and villages), lakes and rivers.
The topology file defines which features are to be displayed, their color, maximum zoom visibility, icons, and labelling. This file can be customised, for example to add or remove specific layers. Details on the file format will be provided in a separate document. The topology data itself uses ERSI Shapefiles which are generated from the freely available VMAP0 database.
Topology files for various regions can be obtained from the XCSoar website. Additional topology files can be produced upon request.
