FAQ
PMTILES to CG4 Conversion
What are PMTILES files?
PMTILES is a single file that holds a whole web map, cut into thousands or millions of small tiles at every zoom level. Normally a map like this is stored as a huge folder tree with one file per tile, which is slow to upload and needs a server to hand out the right pieces. PMTiles packs all of them into one file with a built-in index, so it can simply be put on cheap file storage in the cloud, and a map in a browser downloads only the tiles it needs to show the current view. The format was created by Protomaps, and it can hold vector tiles, which stay sharp at any zoom, as well as pictures such as aerial or satellite imagery.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
