Grant Administration - SPDC Staff
The GIS and GPS systems in use at SPDC are used primarily to support grant projects, both in the application phase as well as through administration of the grant. The system and the data and maps produced are used by the staff for planning, documentation, and as a part of the actual application. GIS is also used to support planning in the Indoor Plumbing program and the Comprehensive Economic Development Strategy.

GPS Mapping Projects
GPS can be used to map real-world facilities such as manholes, water valves, and hydrants. Our system is capable of survey-grade accuracy, although we cannot guarantee that the data provided will be that accurate, as we are not licensed surveyors. We do strive for the highest accuracy available, however. For the best results, we use a base station + rover setup, with the base station set up on a known point and the rover used to do the mapping in the field. Project deliverables can include GIS data for use by consultants doing work for the locality, as well as electronic or paper map sheets and books. Please see our projects page for more information on GPS projects that we are working on.
