Precision maps, created using digital Aerial Photography and/or LiDAR technology supply essential information for engineers.
LiDAR provides detailed (1 to 50 or more measurements per m2) accurate (+/- 10cm vertical +/-20cm horizontal) digital elevation measurements.
This kind of data can be obtained even under heavy forest cover.
Digital elevation data can then be processed to develop a number of maps that are very useful. For example some municipalities have bylaws that state only ground less than 3:1 slopes can be developed on. Topo data can be manipulated into slope maps … areas >3:1 vs areas <3:1 slope
