uniDEM can convert point, vector and polygon data into a DEM and crop shapes into specified bounds.
Shapes To DEM
Geometry data (points, lines and polygons) stored in ESRI shapefile format can be rasterized into a Digital Elevation Model (DEM).
The following parameters are used to rasterize features to a DEM:
Select Dataset - select the shapefile to use when rasters
Select Output
Create a new DEM → define the projection and extents
Apply to an existing DEM
Select Projection - set the projection for the cropped shapes
Enter the DEM parameters - set the pixel spacing and DEM extents
Rasterize polygons as - polygons can be rasterized as area or lines (of a defined width)
Default shortcut: none
Crop/Merge Shapes
Shape data can be cropped to the extent of a drawn polygon.
