geometric geodesy -凯发k8网页登录
2-d and 3-d coordinate systems; distances, areas,
and curves on the earth
using toolbox functions and reference spheroid classes, you can perform geodetic calculations that account for the curvature of earth and other planetary bodies. these include 2d distances, directions, areas, special curves (geodesics, rhumb lines, small circles, ellipses), and intersections on a spheroidal or planar surface. these also include transformations of 3d locations and vectors (such as, velocities and gradients) between geodetic, earth-centered earth-fixed, and local (east-north-up, north-east-down, azimuth-elevation-range) systems.
categories
represent shape and size of the earth, create reference ellipsoids, convert between latitudes
transform coordinates and vector components between global and local systems; find intersection with spheroid
convert between different angle and length units and perform longitude wrapping; convert units of distances along the surface of the earth
find shortest path between two points, find curve that crosses meridians at same angle
define small circles and ellipses
find areas bounded by meridians or parallels, find quadrangles surrounding points
