FAQ
BIL to CGM Conversion
What are BIL files?
BIL is a binary raster format developed by ESRI to store multi-band remote sensing data, hyperspectral imagery, and continuous surface models such as Digital Elevation Models (DEMs). As an uncompressed layout where pixel data is organized sequentially by lines across all available spectral bands, a file of this type cannot be read independently because it completely lacks embedded geospatial or structural metadata. To function within a geographic information system, a .bil file must be accompanied by a plain-text sidecar file with a .hdr extension, which explicitly defines critical parameters including the total number of rows and columns, the band count, the data type, byte order, and optional georeferencing information. This raw format is traditionally complemented by other sibling files like .blw for spatial coordinates, .stx for statistics, and .prj for the map projection.
What are CGM files?
CGM (Computer Graphics Metafile) is a format that contains vector graphics information (clip art, drawings) associated with graphics design or CAD programs. As opposed to other types of metafiles, such as EMF or WMF, CGM files are not only supported by Windows, but can be used on different platforms too. They are encoded using binary, character-based of clear-text encoding.
