FAQ
ERS to HPG Conversion
What are ERS files?
ERS is the header file of the ER Mapper raster format, developed for the ER Mapper image processing software, now part of ERDAS. A dataset of this type consists of two files: a plain-text header with the .ers extension and a binary data file with the same base name and no extension. The header describes the data in a structured, readable form, including the number of lines, cells, and bands, the data type of the pixels, the cell size, the byte order, and the coordinate system. The data file stores the pixel values themselves, without compression. The format is used for satellite and aerial imagery, geophysical grids, and elevation models, particularly in mining, exploration, and remote sensing, and it is recognized by many mapping and geoscience programs.
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.
