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.
