LERC (Limited Error Raster Compression), also written Lerc, is a format for compressed raster image data. It was developed by Esri.
It may appear in a file by itself, or as part of MRF format, or be used as a compression method in a format such as GeoTIFF.
There are two major versions, known as "Lerc1" and "Lerc2".
