Profile Look Ahead Distance

A Progress GridClosed A type of DTM that is made manageable through sampling measured points into a regularly spaced raster, allowing fast and conditional access. Considered to be a secondary data set; since no original points are kept.., filled with data, is needed for this, so you can look ahead at the seabed.

This option is useful in areas with slopes, so you can adjust the settings of your multibeam echosounder beforehand.

If necessary, enter a distance in meters.
