Dem Reader

Speleology for connaisseurs is the science of cave exploration, and like all other disciplines, it too has taken a step into the digital age. Cave mapping is usually done with specialized software that generates Digital Elevation Models (DEM files) for the efficient 3D projections of a cave's terrain. Given how proprietary this file format may seem, there aren't many software tools out there capable of viewing or editing such formats. However, there are some exceptions, one of which is Dem Reader.

You don't need a manual to know how to use this tool since the UI is pretty self-explanatory and easy to comprehend. All you need to do is have a DEM file at your disposal and you can pretty much do anything with it, including basic editing, merging, conversion and so forth. More so, the data on the DEM files can be modified with manually inputted values, which is useful if you think the measurement devices registered values that don't reflect reality.

Ss most of you probably know, elevation maps are usually color-coded to show off the difference in height in various geographical regions.  Dem Reader allows you to modify this color coding, so that it may be easier for you to distinguish different elevation levels. Massive caves usually require multiple readings and thus, a single DEM file would not be enough to contain all the necessary data.  This is where Dem Reader shines since it allows you to merge multiple DEM files into one, allowing you to get a reading of any cave, no matter how big or elaborate it may be.

Dem Reader has all the tools you may need to view and edit DEM images without filling your PC with complicated or resource-hungry software suites.
