FAQ
ERS to CAL 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 CAL files?
A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
