3D WGS84 Earth

Rotating 3D Earth. WGS84 ellipsoid.

1 Features

• 3D WGS84 ellipsoid
• Rotation of earth, selectable speed
• Relief with exaggerated elevations
• Data tip in geographic coordinates and elevations in meter
• Example to plot on earth
• Example to plot on texture

2 Method

Out of geographic coordinates in one degree steps a geocentric x, y, z mesh grid is created by sin and cos functions. This mesh grid is placed to form a WGS84 ellipsoid. The texture within the meshes is overlaid by Matlab’s surface function.

3 Syntax

plot3Dearth                                     %  default texture, flat relief
plot3Dearth(0,50)                               %  default texture, elevations exaggerated by factor 50
plot3Dearth('land_ocean_ice_8192.png', 100)     % Texture out of folder 'texture', elevations exaggerated by factor 100
plot3Dearth('c:/myFolder/myTexture.jpg')        % Texture out of other folder, flat relief
