Additionally, the ability of the engineer to check elevations at any point within the R3D imagery provides
extremely useful information beyond the normal limits and detail of surveys produced for purposes of project
development studies. As a result, requirements for supplemental field survey work can be minimized resulting in
cost savings at the project development phase. The State Project Development Engineer has indicated that the threedimensional data product used by District 3 Planning provides the accuracy required for project development
studies.
