For over five years Laberge Group has provided survey and mapping services to Lafarge N.A. (formerly Blue Circle Cement) at their cement plant located in Ravena, New York.

These services include annual topographic surveys of coal, bauxite, gypsum, petcoke and aggregate stone stockpiles to determine volumes, a GPS Survey of 10 square miles of photogrammetric control points for a 100-year master plan map, and a topographic survey, cross sections and mapping of 7,000 linear feet of ditches, streams and ponds, together with a bathymetric survey of each pond.
