FAQ
GRC to PPM Conversion
What are GRC files?
GRC is the classified grid format of Vertical Mapper, a spatial analysis add-on originally created by Northwood Geoscience in Canada and later acquired by MapInfo. A file of this type is a map made of equal cells, and each cell carries a category rather than a measurement, for example a land use class, a soil type, or a signal strength range. The category names and colors are stored with the map, so it can be displayed immediately. Its numeric counterpart, the .grd file, stores smoothly varying values such as elevation. The GRC format is widely used for mobile network planning, where coverage predictions around cell towers are saved as classified grids, and it is also used in mapping, environmental analysis, and land management.
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.
