# GeoDLL - Geodetic Development Kit Function group "Distance Calculations"

GeoDLL - Function Groups

Continental Drift
At present 2 to 7 cm per year

## GeoDLL - Accurate Distance and Bearing Calculations

GeoDLL supports the development of geodetic software by providing geodetic functions, which are put together into function groups for specific tasks. To use accurate distance and bearing calculations in own developments a license for the function group "Distance Calculations" can be purchased.

The group "Distance Calculations" contains functions for the calculation of the distance between two coordinates. Other functions calculate the coordinate of a target point based on the parameters start point coordinate, bearing and distance. According to the formulas of Vincenty the Direct Position Computation and the Inverse Position Computation will be done.

### Characteristics of the group "Distance Calculations"

1. Distance between coordinates on the ellipsoid
2. Distance between coordinates on the sphere
3. Distance between UTM coordinates
4. Destination point from start point, bearing, distance on ellipsoid
5. Destination point from start point, bearing, distance on sphere
6. UTM destination point from UTM start point, bearing and distance
7. Vincenty's Direct and Inverse Position Computation
1. Distance, forward bearing, backward bearing

### Functions of the group "Distance Calculations"

1. Function distancegeo() - Distance between geogr. coordinates on the ellipsoid
2. Function distancesphere() - Distance between geogr. coordinates on the sphere
3. Function distanceutm() - Distance between UTM coordinates
4. Function point2pointgeo() - Dest. point on ellipsoid from start point, bearing, dist.
5. Function point2pointsphere() - Dest. point on sphere from start point, bearing, distance
6. Function point2pointutm() - UTM dest. point from UTM start point, bearing and distance
7. Function vincentydirect() - Vincentys Direct Position Computation
8. Function vincentyinverse() - Vincentys Inverse Position Computation
