.blw - ArcGIS BIL World File
The BLW gis files are related to ArcGIS. BLW file is an ArcGIS BIL World File. BLW files are the ASCII files containing information for geocoding image data. Some image formats, such as ERDAS IMAGINE, BSQ, BIL, BIP, GeoTIFF, and grids, store the georeferencing information in the header of the image file. ArcGIS uses this information if it is present. However, other image formats store this information in a separate ASCII world file, since it contains the real-world transformation information used by the image.
