| What is Geographic Referencing? |
|
All geographic data, by definition, has some sort of geographic referencing to help identify its location in the world. There are many possible means of describing your location. Some of these include georeferenced coordinates (such as latitude/longitude), coordinates whose relationship to the earth is not known (such as some survey data), linear referencing (such as street addresses and mile markers), more general land referencing (such as tier/range/section in the Public Land Survey System) and indirect positional references (such as distance and direction descriptions from know markers in the field - [30' west of the "old oak tree"]). Geographic referencing standards help define common ways to collect and reference data. This in turn provides a more effective way to share information collected by different agencies. The standards in this section are current referencing standards in use by the state.
