Organizing and Manipulating Map and Geospatial Data

The Mapping Toolbox helps you organize and manipulate map and geospatial data for map displays and computational analyses. Toolbox functions for handling vector coordinate data let you:

• Extract structure fields and coordinates from variables in the MATLAB workspace and from ESRI shapefiles
• Increase (interpolate) or reduce the density of points in coordinate vectors
• Convert among units and formats for length, angle, and time
• Split, merge, or join line and polygon segments
• Trim vector data to a specific region
• Compute line or polygon intersection points
• Compute buffer zones

With Mapping Toolbox functions for handling georeferenced imagery and gridded data, you can:

• Convert subscripts of data arrays and images to or from absolute geographic or map coordinates
• Convert geolocated data arrays to or from regular data grids
• Trim data to a specific region
• Resize or resample data grids and images

Projecting Map and Geospatial Data

The Mapping Toolbox contains more than 60 of the most popular and important map projections, including equal-area, equidistant, conformal, and compromise projections in the cylindrical, conic, and azimuthal classes. It also supports projections in the popular PROJ.4 library. Specific support is included for the UTM/UPS systems. Many projections support both spherical and ellipsoidal models of the Earth and other bodies.

With the Mapping Toolbox, you can apply forward and inverse transformations of positions and direction angles or azimuths. You can also explore the properties of your projection by calculating distortion parameters at a point or visualizing map distortions as Tissot Indicatrices or as scale-distortion contours.
