Mapping Toolbox

2D and 3D Map Displays

Mapping Toolbox provides visualization functions and an app for producing customized 2D and 3D map displays. The map displays can be simple or sophisticated, and can be tuned to your application. You can readily combine raster and vector data sets of different scales in the same display. For example, you can display images and data grids in their correct positions—regardless of resolution or area covered—and then overlay vector map features.

With the visualization functions in the toolbox, you can:

  • Create 2D map displays with raster and vector data
  • Create 3D map displays with customized lighting, shading and perspective
  • Create contour maps from raster and geolocated grid data
  • Create thematic maps, drape imagery over 3D surfaces, and display maps as images

Map displays can be defined, customized, and annotated in a variety of ways. You can:

  • Use latitude-longitude coordinates or one of many projected coordinate systems
  • Choose from more than 65 map projections in the cylindrical, conic, and azimuthal classes
  • Customize map properties, such as latitude and longitude limits and origin
  • Add a scale ruler, north arrow, contour labels, and legends
  • Display point data as scatter, quiver, stem, and symbol-based features
  • Control map marker symbols, colors, and line styles
  • Vary transparency of polygons and raster data grids
  • Apply colormaps suitable to contour lines, filled contours, terrain and bathymetric grids, and political maps

Function-level access to map display capabilities in the toolbox enables automatic creation of frequently used map displays. For example, you can use batch mode processing to examine a geospatial time-series data set and create an animated display that shows how the data changes over time. Functionality in MATLAB enables you to save animated map figures to a movie or GIF file.
