FAQ
GML to HPG 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 HPG files?
HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.
