Accurate and complete survey and mapping for large scale projects can be completed in an efficient cost effective manner.  Sleighter engineering will set ground control targets and coordinate photogrammetric services with aerial mapping companies.  Any field components that cannot be picked up by aerial mapping will be field surveyed.  Large scale projects often include wetland and stream surveys.  Sleighter Engineering will combine aerial mapping data, wetland/stream data and field survey data to provide a final mapping product.
