Basics
- A Method of Satellite Navigation/Survey that utilizes one or more constellations, and a Base Station
- This allows for 1cm Level Accuracy
- Refresh Rate Typically Can Be ~1hz, but 20hz Models Exist (According to SparkFun, further looking around can be done if need be)
- Useful mainly for Surveying and Precise Remotely Operated / Autonomous Vehicles
- Low cost cm accuracy in GPS using GLNS module with android - [1]
How Are Boundaries Recorded
- There is a legal description like [Sec 32, T8N, R1E, E 1/2 of NW 1/4 Ex Com at NW Cor of Sd E 1/2 of NW 1/2, Th E Alg N Ln of Sec 140 ft, S Parl with N&S 1/4 Ln of Sec 311 Ft. W Parl With N Sec Ln 140 ft, N 311 Ft to Beg)] [2]
- Missouri has corner posts at all sections (mile squares) and at the quarter section (mid point between section corners) [3]
Available Data Sets
- Online parcel map with acreage, soils map, slope [4]
- Missouri plats for acreage, NCCPI, slope, and crops produced, parcel ID - [5]. Ex Savannah 1 acre [6]
