State Property Transfer GIS 4100 Dr. Oetter By Shea Groebner and Michael Bender May 4, 2004

Problem Statement Our project arises from a proposal to transfer some Central State property to the Baldwin State Forest. A boundary description of the area to be transferred is necessary. We plan to use GPS information obtained in the field as well as GIS to create and map the new boundary line. The importance of this survey is so that the state does not have to pay a surveyor thousands of dollars to complete the description.

Mission Statement of Central State Hospital “…to serve the needs of people with mental illness, developmental disabilities, and substance abuse while emphasizing habilitation and health and providing acute medical services and skilled and supportive nursing care, as we seek continuing improvement in the quality of our care”.

Mission Statement of State Forest Lands “…these lands incorporate forest stewardship (multiple resource) management, including forest products, wildlife, recreation, soil and water conservation, aesthetics, historical and cultural resources”.

FROM_IDTO_IDCENT_BEARCENT_DIST Bearings and Distances Between Points

Increase accuracy and precision of points used Locate more of the existing survey pins from previous surveys of the area Establish precise and accurate control points Find extension enabling you to put in bearing and distances from a known control point to establish other points( granite markers from adjacent properties) Find extension enabling you to calculate area of each polygonal tract Separate tracts defined using bearing and distances from control points Suggestions and Additional Work Required for Survey Grade Completion

Pitfalls and Speedbumps Should not have tried to use contour lines (not acceptable for survey work) Handheld GPS not accurate enough All points and lines need to be referenced to existing control points Equipment check prior to taking into the field Recent transfers and surveys may not be on the courthouse aerial property photos (Alltell property and Selma Transfer)
