FAQ
BSQ to HPG Conversion
What are BSQ files?
BSQ is a raw binary raster format developed by ESRI to store multi-band geospatial data, such as multispectral satellite imagery, aerial photography, and thematic surface classifications. As an uncompressed layout where data is organized sequentially by entire spectral bands—writing the full spatial matrix of the first band before starting the second—a file of this type contains no internal metadata, georeferencing, or projection tags. To function properly within a geographic information system, a BSQ file requires a mandatory plain-text sidecar file with a .hdr extension that explicitly defines structural parameters like row and column counts, band numbers, and data types. This format is typically accompanied by other sibling files, including .bsw for spatial world coordinates 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.
