DEM data file (*.txt)

A DEM data file (*txt.) is a type of file for saving the x-, y- and z- coordinate values of a point.

It can be used as a file type for importing elevation data for iRIC.

A DEM data file is a CSV-delimited text file. It gives one height datum to one plane coordinates (x, y). Each column has the following meaning:

  • Index of the coordinates (iRIC skips it)
  • x-coordinate
  • y-coordinate
  • z-coordinate (elevation)
