Dynamic representation of geographic line and polygon features with

geoshape class

Geographic multi-point, line, and polygon features, in a geographic coordinate system,

are represented by a geoshape vector.

Dynamic representation of point, line, and polygon map features with

mappoint and mapshape classes

Geographic point feature, in a planar coordinate system, are represented by a mappoint

vector. Geographic multi-point, line, and polygon features, in a planar coordinate system,

are represented by a mapshape vector.

Coordinate transformations to/from local east-north-up, north-east-

down, and spherical systems

A new set of 20 functions for transforming between 3-D coordinate systems has been

introduced. There are two global coordinate systems: the geodetic system and ECEF

(Earth-Centered, Earth-Fixed) system. The three local coordinate systems are ENU

(east-north-up), NED (north-east-down), and AER (azimuth-elevation-range).

• Geodetic to local coordinate transforms: geodetic2enu, geodetic2ned,

geodetic2aer

• ECEF to local coordinate transforms: ecef2enu, ecef2ned, ecef2aer

• Local to geodetic coordinate transforms: enu2geodetic, ned2geodetic,

aer2geodetic

• Local to ECEF coordinate transforms: enu2ecef , ned2ecef, aer2ecef

• Transformations between local systems: aer2enu, aer2ned, enu2aer, ned2aer

• 3-D vector transformations between the three Cartesian systems (ECEF, ENU and

NED): enu2ecefv, ned2ecefv, ecef2enuv, ecef2nedv

Geographic quadrangles bounding points and lines with geoquadpt

and geoquadline functions

geoquadpt computes a geographic quadrangle bounding scattered points. geoquadline

computes a geographic quadrangle bounding a multi-part line. Both functions account for

spherical topology.
