Elevation Options Section

Parent Previous Next


For elevation datasets, the following options can be set:

Elevation units (m): The length of an elevation unit in the raw data, expressed in meters. If for example, the raw data specifies altitudes in feet, this option should be set to “0.3048” because 1 foot = 0.3048 meters. This setting can also be used to exaggerate the elevation model.

Mask value: If this value appears in the raw data, it will be interpreted as “no data” and the resulting dataset will contain no elevation information at this point.
