			The information content of the feature map depends on the terrain type, the settings and the quality of the LiDAR data, in particular the point density.<br>
			With good data quality, the feature map can be a useful addition to the existing background maps.

			'''Example'''

			''Slope Gradient Map''

			[[File:FeatureMapStones.png]]<br>
			''Feature Map''

			[[File:MapStones.png]]<br>
			''Orienteering Map''

			LiDAR data from 2022, 29 points per square meter, 0.5m cell size, 0.0-2.0m threshold.<br>
			In the Feature Map, e.g. stones becomes visible. The stones that are already visible in the Slope Gradient Map are probably overgrown and therefore classified as ground points.

			Credit goes to Jeff Teutsch and his ''Lidar Case Study - Using simple ground reclassification to see features in data''.
