# ERS -- ERMapper .ERS

GDAL supports reading and writing raster files with .ers header files, with some limitations. The .ers ascii format is used by ERMapper for labelling raw data files, as well as for providing extended metadata, and georeferencing for some other file formats. The .ERS format, or variants are also used to hold descriptions of ERMapper algorithms, but these are not supported by GDAL.
