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.

 

This data can be used in …

• Estimate documents

• Scoping studies

• Proposal documents (3-D fly through)

• Engineered plans

• “As built” confirmation

 

Rate of change maps …

• coastline erosion

• tailing dam change

• urbanization

• illegal miners

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
