TOPOJSON to PPM Conversion
What are TOPOJSON files?
TOPOJSON is a compact text format for maps whose areas touch each other, such as countries, states, or districts. It extends GeoJSON with one important idea: instead of writing the outline of every area separately, it writes every shared border only once, and each area then lists the pieces of border it is made of. This removes the duplicate lines between neighbors, so a TopoJSON file is often many times smaller than the same map in GeoJSON, and it also keeps the information about which areas share a border. Because of its small size, the format is popular for maps on web pages, where files have to be downloaded quickly. The files have the .topojson extension, although .json is also used.
What are PPM files?
PPM or Portable Pixelmap files are image files included in Netpbm, an open source graphics program. The other widely used Netpbm formats are PGM (Portable Graymap) and PBM (Portable Bitmap). All three are image formats and are sometimes called collectively PNMs (Portable Anymap format). While PGMs contains grayscale images, PPMs include color images and they represent intermediary files used in the conversion of less known formats using the Portable Bitmap Utilities. PPM files are mostly operated on UNIX and Intel-based platforms.
