Remarks

Densifies each polyline or polygon in the input array by plotting points along the geodesic paths between existing vertices. MaxSegmentLength is expressed in some linear unit of measure. If the LengthUnit parameter is specified, then MaxSegmentLength is expressed in those units. If the LengthUnit parameter is not specified, then MaxSegmentLength is expressed in the the linear units of the input spatial reference, if the spatial reference is a projected coordinate system. Otherwise, it is assumed to be expressed in meters.

If the spatial reference is a projected coordinate system, then the input geometries will be inversed projected, geodesic path points will be plotted, and the result will be forward projected into the same spatial reference.

The figure below illustrates the DensifyGeodesic operation applied to a polyline with 3 vertices, with a max output segment length of 10,000 meters.
