# GeoDisplacement

GeoDisplacement[{dist,α}]

represents a geodesic displacement of length dist and initial bearing α from a geo location.

GeoDisplacement[{dist,α},pathtype]

represents a displacement of length dist and initial bearing α along a path of type pathtype.

GeoDisplacement[loc1,loc2,pathtype]

returns the displacement needed to reach loc2 from loc1 along a path of type pathtype.

# Details • The distance dist can be given as a Quantity length or as a number in meters.
• The bearing α is measured clockwise from true north (geodetic north). It can be given as a Quantity angle, a number in degrees, a DMS string, or a named compass point like "N" or "SouthWest".
• Locations loci in GeoDisplacement[loc1,loc2,pathtype] can be given as geographic Entity objects, {lat,lon} pairs in degrees, GeoPosition objects, or any other geodetic position specification.
• GeoDisplacement[loc1,loc2] assumes a path of type "Geodesic".
• The list of possible path types is given in the documentation of GeoPath.
• GeoDisplacement can be used with GeoDestination to compute sequences of displacements and with GeoPath to draw them.
