As a subconsultant on a pipeline mapping contract, GRW provided new aerial photography, aerotriangulation, DEM surface creation, planimetric mapping, and .5’ pixel digital orthophotos for 780 miles of pipeline across South Carolina. The project supported South Carolina Pipeline’s GIS and Mapping Program, including mapping for high concentration areas.
Planimetric features were collected for a 1600’ corridor along the pipeline, including buildings, roads, railroads, hydrography, and vegetation. Data included as-built plan profile sheets in AutoCAD and ESRI shapefile format. The DEM surface was collected to support the generation of .5’ pixel orthophotos for a 3,200’ corridor. All ortho data was delivered in TIF and MrSID format.
