Globe Frame on Map Axes

Display polygons and surfaces with shading and lighting

Visualize data using polygons and surfaces on a globe display. For example, you can drape data over elevation maps, apply lighting, or exaggerate terrain. Create a globe display using map axes and a globe frame.

Globe Display

The Globe Display Compared with the Orthographic Projection

This example illustrates the differences between a 2-D orthographic projection, which looks spherical but is really flat, and a 3-D Globe display.

Use Opacity and Transparency in Globe Displays

This example shows how to create an opaque surface to hide lines on the far side of a globe.

Shade and Light Terrain Maps

Light a Terrain Map of a Region

Add lighting and shading to terrain maps, then set surface reflectance properties.

Surface Relief Shading

A shaded-relief map models illumination over a surface to highlight the texture of the surface.

Colored Surface Shaded Relief

This example shows how to illuminate surface texture over colored elevation data using shaded relief computations.

Relief Mapping with Light Objects

This example shows how to illuminate surface texture over colored elevation data using a light source.

Drape Data on Elevation Maps

Drape Data on Elevation Maps

You can drape satellite data over a grid of elevations in order to see the topography of the surface.

Drape Geoid Heights Over Topography

This example shows how to drape the figure of the Earth, shown as an attribute (color) data grid, on topographic relief.

Combine Dissimilar Grids by Converting Regular Grid to Geolocated Data Grid

This example shows how to combine an elevation data grid and an attribute data grid that cover the same region but are gridded differently.

Drape Geolocated Grid on Regular Data Grid via Texture Mapping

This example shows how to create a new regular data grid that covers the region of the geolocated data grid. You can embed the color data values into the new matrix.
