FAQ
BT to XBM Conversion
What are BT files?
BT is a binary terrain format developed by Ben Discoe for the Virtual Terrain Project (VTP) to store regular elevation grids used in 3D terrain visualization and simulation. A file of this type consists of a fixed 256-byte header followed by an uncompressed array of elevation samples, stored as 16-bit integers, 32-bit integers, or 32-bit floating-point numbers. The header carries the grid dimensions, sample size, horizontal units, geographic extents, datum, and, for projected data, a UTM zone, while a complete projection definition may be supplied in an accompanying .prj file. Elevation samples are written column by column, starting from the western edge and moving south to north within each column. The format is used to exchange digital elevation models between terrain-building tools and visualization software, and is often distributed in a gzip-compressed .bt.gz form.
What are XBM files?
The XBM (X BitMap) format represents a monochrome image file usually used for storing cursor and icon bitmaps in the X graphical user interface. XBMs store data as C language data array, so they can be included directly into an application. They are, however, fairly large in size. In the late 1980s the XBM format was superseded by the XPM format for the X Windows System.
Can reaConverter convert BT to XBM?
