Linking Cave Surveys To Real-World Coordinates.

It is sometimes useful to fix the location of the entrance (or any station) of a cave to a geographic reference system such as longitude, latitude or UTM. In Compass, real-world coordinates are entered at the project level. There are some big advantages to doing things that way. The main advantage is that you can setup several different projects using same data and different sets of fixed coordinates. For example, one project could use UTM, another could use a local land survey and a third could use no fixed coordinates at all. You can also build projects using different combinations of caves, surface surveys and references. For complete information about fixed coordinates, see the Project Manager help.
