Mapping Toolbox

Data Representation and Transformations

Vector Data Representation

With Mapping Toolbox, you can work with vector data as X-Y or latitude-longitude vectors or as objects where other metadata can be maintained and organized. In both cases, the toolbox provides functionality to help you manipulate the data, including splitting, merging, and reordering data points. It also provides functionality to interpolate between waypoints and increase the sample density of your data with several interpolation techniques.

Coordinate Transformations

Mapping Toolbox provides a variety of coordinate transformations for the common system conversions required when combining data from multiple sources. You can perform 3D geometric computations in the near-earth environment and transform point locations between 3D geodetic, geocentric, local east-north-up (ENU), local north-east-down (NED), and local spherical systems. These transformations include core functionality, over which 3D datum transformations (Helmert and Bursa-Wolfe) can be implemented, for example, to combine data referenced to WGS84 with legacy maps based on older datums.

Geographic Data Utilities

Many functions are available to work with raster, image, and other grid-based data. You can modify spatial resolution, convert pixel indices to map coordinates, and extrapolate irregularly sampled data points into a grid. Other Mapping Toolbox utility functions enable you to perform unit and angle conversions, wrap longitude and azimuth angles, and format angle and distance strings.
