dem-gmrf

An application for generating Digital Elevation Models (DEM) with Gaussian Markov Random Fields (GMRF). Works on Windows, GNU/Linux and Mac OS.

Installing

  • Windows binaries:
    • (Write me!)
  • Building from sources requires:
    • A C++ compiler: GCC, clang, Visual C++ 2012 or above recommended.
    • MRPT >= 1.4.0

Input file formats

  • XYZ: Plain text file, each row containing one height (Z) measurement: (separated by whitespaces or commas ,)

    1.   X    Y    Z

  • XYZS: Plain text file, each row containing one height (Z) measurement and its uncertainty (standard deviation): (separated by whitespaces or commas ,)

    1.   X    Y    Z  STD_DEV

Usage

  1.        dem-gmrf  [--no-gui] [--skip-variance] [--std-obs <0.20>] [--std-prior
  2.                  <1.0>] [-c <0.01>] [-o <demgmrf_out>] [-r <1.0>] -i <xyz.txt>
  3.                  [--] [--version] [-h]
  6.     Where:
  8.        --no-gui
  9.          Do not show the graphical window with the 3D visualization at end.
  11.        --skip-variance
  12.          Skip variance estimation
  14.        --std-obs <0.20>
  15.          Default standard deviation of each XYZ point observation [meters]
  17.        --std-prior <1.0>
  18.          Standard deviation of the prior constraints (`smoothness` or
  19.          `tolerance`of the terrain) [meters]
  21.        -c <0.01>,  --checkpoint-ratio <0.01>
  22.          Ratio (1.0=all,0.0=none) of data points to use as checkpoints. They
  23.          will not be inserted in the DEM. (Default=0.01)
  25.        -o <demgmrf_out>,  --output-prefix <demgmrf_out>
  26.          Prefix for all output filenames
  28.        -r <1.0>,  --resolution <1.0>
  29.          Resolution (side length) of each cell in the DEM (meters)
  31.        -i <xyz.txt>,  --input <xyz.txt>
  32.          (required)  Input dataset file: X,Y,Z points in plain text format
  34.        --,  --ignore_rest
  35.          Ignores the rest of the labeled arguments following this flag.
  37.        --version
  38.          Displays version information and exits.
  40.        -h,  --help
  41.          Displays usage information and exits.
