Mapping
Widmer Engineering Inc. has mapped and located thousands of feet of sewer line and has
prepared comprehensive base mapping for our municipal clients. Whether with the use of
aerial photogrammetry or through conventional surveying techniques, our staff can
provide you with the mapping to meet the DEP requirements.
We also have in-house global positioning equipment to place all data on the Pennsylvania
State Plane Coordinate System or have it tied to a local coordinate system. We have
special locating equipment to trace the underground positions of our internal sewer
inspection camera or through the use of low voltage electricity to trace underground
utilities and place them on the base mapping.
