ER Mapper Raster
ER Mapper Raster (sometimes called ERS) is a raster image file format associated with the ER Mapper and ER Viewer products currently owned by Hexagon Geospatial. "ER" stands for Earth Resource.
It was once owned by ERDAS, so it may be called ERDAS ER Mapper, or a similar name.
It consists of a text-based .ers file containing image attributes and metadata, and another file (usually with no extension) containing the image data.
The .ers file likely begins with a line that reads "
DatasetHeader Begin", and contains a line that reads "
DataType = Raster".
