[[File:DEM.jpg]]


OCAD DEM Module can Import regular and irregular DEM data files. Supported DEM formats are: ESRI ASCII Grid and xyz file. Binary files are not supported.
A laser beam splits as it hits objects. The result are multiple returns. The difference between first and last return can show object height. The last return doesn’t always reach the ground.

# Then '''Analyze''' the DEM to get some information about the DEM like extent, cell size etc.
Read more about importing DEM file on the page [[DEM Import Wizard]].
# If the source file is a regular grid (Data type of import files = Grid), the '''Cell size''' box is set to read only. OCAD sets the same cell size for the imported DEM. For irregular source DEM (Data type of import files = Raw) the cell size can be set in the cell size box. For these DEM OCAD interpolates a regular grid with the specified cell size during the import.  
# At the end of the import procedure the imported DEM must be saved in OCAD DEM file format (*.ocdDem) and it is loaded to the OCAD map.
# To see the extent of the loaded DEM active '''Show Frame''' menu item.


: [[File:Hint.jpg|hint]] The '''Cell size''' has to be an integer value. The minimum Cell size is 1m.

A DEM (Digital Elevation Model) contains points with elevation data. DEM Data are based on LIDAR (Light Detection and Ranging) technology measurement, also known as Airborne Laser Scanning. There are DEM with point data arranged in a regular grid with a constant distance between the points. This distance is called cell size. Other DEM contain data points arranged irregularly (cloud-model).
