GML to PGM Conversion
What are GML files?
GML (Geography Markup Language) is an XML-based language for describing geographic features, developed by the Open Geospatial Consortium (OGC) and adopted as the international standard ISO 19136. A GML file is readable text in which every object on a map, such as a building, a road, a lake, or a boundary, is written down together with its shape and its attributes, for example a name, a type, or a population. The language is a toolbox rather than a fixed list of objects: communities and organizations define their own application schemas on top of it, which is how national mapping data, cadastral records, and the data of 3D city models are exchanged. GML is also the standard way for web map services to return features.
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.
