COGO Coordinate Geometry software for Land Surveyors


Fast, Easy COGO for Land Surveyors

ProCogo provides you with quick, straightforward coordinate geometry for your land surveying or civil engineering business without all the hassle and expense of big CAD based systems. Instead of waiting for your big CAD/Survey COGO system to load just to get a quick point list or stakeout sheet, ProCogo's clean intuitive user interface lets you do the COGO calculations you need and the get the printouts you want in record time. In addition, ProCogo can work with other land surveying software such as TIN Master and our Legal-Aid - legal description writer to give you contouring and legal description capabilities.
