FAQ
FGB to PGM Conversion
What are FGB files?
FGB is the extension of FlatGeobuf, a modern binary format for geographic vector data, created by Björn Harrtell and published as open source. A file holds a collection of features, which are points, lines, and polygons with their attributes such as names and codes, together with the coordinate system and the extent of the data. The format is built for speed: an optional spatial index, built in a smart way, lets a program pick out only the features in a chosen area without reading the whole file, and the same trick works over the internet, where just the needed bytes are downloaded. Files are written once and then read many times, which suits large collections of static data, and the format has no size limit of the kind that older formats like Shapefile have.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
