SIGDEM to OBJ 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 OBJ files?
OBJ is a 3D model format created by Wavefront Technologies for its Advanced Visualizer software and now supported by almost every 3D application, which makes it one of the most common formats for exchanging models. A file of this type is plain text that describes the shape of an object: the coordinates of its vertices, the texture coordinates used for UV mapping, the surface normals, and the faces that join them into polygons. Named groups divide a model into separate parts. Colors and materials are not stored in the file itself but in a separate .mtl file that it refers to, with the texture images kept alongside. The format holds a static model only, with no animation, bones, or lights.
Can reaConverter convert SIGDEM to OBJ?
Yes! reaConverter instantly converts .sigdem to .obj with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert SIGDEM files directly from Windows Explorer using the right-click menu — fast and convenient.
What is reaConverter used for?
reaConverter is a Windows converter for 800+ formats, GIS data among them. For SIGDEM to OBJ it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.
Why choose offline conversion with reaConverter?
reaConverter is a software program that is used for offline files conversion.
