High-precision land-cover-land-use GIS mapping was performed in four major townships in Maine’s Aroostook River Valley, using on-screen digitization and direct interpretation of very high spatial resolution satellite multispectral imagery (15–60 cm) and high spatial resolution LiDAR data (2 m) and the field mapping method. The project not only provides the first-ever high-precision land Cited by: 3. Map View 29 QGIS User Guide, Release Figure Define a legend independent layer order above.

• Place more points by clicking further along the edge, until the shape you’re drawing completely covers the field. • After .extract a slice to a 2D raster map with: t= b= in=vox50 out=vox50x Vector 3D point data.
Historical note: known as "site data" in GRASS GIS 5. In the "typical" case, "z" data is stored as a non-spatial attribute in a vector point map. In GRASS 6 it is possible to create 3D vector files, i.e.
points exist in 3D space.
