FAQ
SIGDEM to DXF Conversion
What are SIGDEM files?
SIGDEM (Scaled Integer Gridded Digital Elevation Model) is a compact binary format for storing a grid of terrain heights. Instead of saving each height as a bulky decimal number, it records a whole number together with a scale and an offset, from which the true height is calculated, and this keeps the files small while retaining the accuracy needed for mapping work. A file of this type holds exactly one layer and begins with a short header that gives the position of the grid, the cell size, the scale factors, and the coordinate system, which is usually specified by its EPSG number. Files can also be packed with gzip or zip and keep the same extension in front. The format is open, and its specification is published on GitHub.
What are DXF files?
DXF (Drawing Exchange Format) is a format associated with AutoCAD, a popular program used for computer-aided design by engineers, architects and other professionals in the field of building design and construction. The DXF format was developed in the early 1980s by Autodesk with the purpose of increasing the interoperability between AutoCAD and other CAD or advanced image design programs. It supports 2-dimensional and 3-dimensional drawings, and can be opened using a wide array of image processing programs.
