GetProjectionFactor
Unit functions GetProjectionFactor
- GetProjectionFactor(gridunit)
GetProjectionFactor(gridunit) results in a parameter with a dpoint value type, indicating the gridsize in both X and Y directions.
The grid size is expressed in the unit of the coordinate system.
The GetProjectionFactor function in combination with the GetProjectionFactor function was used to calculate grid relations for a set of points.
Since GeoDMS version 7.015 this is done with the value function, see Configuration examples Grid.
