FAQ
BIL to HPG 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 HPG files?
HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.
