Coordinate Conversion Details

Get one-step conversion between any of the supported coordinate systems including datum shifting.

ProLat for .Net has a new and easy way to specify coordinate systems with four descriptive strings: Group, System, Datum, and Units. For example, to get a UTM zone 20 coordinate system, use "UTM", "UTM-20N", "WGS84", and "METERS". In addition, ProLat supports Proj.4 definition strings.

Converts whole arrays with one function call. Datum to datum conversions use NADCON grid methods for highest accuracy. Regions not defined by NADCON are done with 3, 7, or 10 parameter formulas. A special function is included to read a text list of DMS formatted coordinates. Reads many formats such as 101d52'37.46"W and W101 52.62433 with ease. Based on parser technology, this function alone will save days or weeks of programming.

Geodesic shortest distance calculations accurate to the ellipsoid. Calculates forward and back azimuth. MGRS conversion with both UTM and UPS zones.

Here is an example conversion from latitude/longitude to UTM:

LatLon = CoordSys.GetCS("LAT_LONG", "LAT-LONG", "WGS84", "METERS")
UTM17 = CoordSys.GetCS("UTM", "UTM-17N", "WGS84", "METERS")

CoordSys.Transform(LatLon, UTM17, lon_x, lat_y, z, 1) ' Transform values in-place

To get a reverse transformation, simply swap the LatLon and UTM17 parameters.
