USER MANUAL

Map source 1 & 2

Choose map for each map source. Operator has an option to select two different map providers. During operation Map toggle button enables switching between the sources.

You can select desired map from the list of available map sources. Maps are downloaded from the Internet and stored on the local disk for later use.

You can create and use your own custom maps as a background of C³P. C³P recognizes raster map tiles in TMS (Tile Map Service) format. To create TMS maps from your georeferenced map images such as GeoTiffs we suggest use of MapTiler or Global Mapper. TMS tiles have to be placed in a new folder created in %APPDATA%\C-Astral\gmapcache\Custom\.To access the folder press Custom map folder button in Custom map section. The name of the new folder will appear on top of the list of available maps in C³P.

WARNING: Filtering applies corrections to altitudes and at the same time removes noise. Be careful when applying filter.

Prefetch up to zoom

You can download a bigger part of the map up to specified zoom level for later use. Change maximum zoom level and a button with "Fetch N tiles for offline use" will appear.
