Vector and Raster Map Display

Display vector or raster data on map

Vector data represents events, locations, and objects using points, lines, and polygons. For example, you can represent a city by using a point, a river by using a line, and a country by using a polygon. Raster data stores gridded data, such as satellite imagery and terrain elevation grids, in matrices. Use these functions to display vector and raster data on maps.

Vector Map Display

Raster Map Display

  • Types of Data Grids and Raster Display Functions
    You can display regular and geolocated data grids in many ways, such as a 2-D indexed image where color represents the data value, or as a 3-D surface with light shading.
  • Fit Gridded Data to the Graticule
    A graticule is a grid of meridians and parallels used to guide the placement of features on a map. Using a finer graticule can give greater precision at the cost of more effort and time.
  • Create 3-D Displays with Raster Data
    This example shows how to create a 3-D display of raster data, where the z-coordinate represents the data values. Change the viewpoint to get the appearance of depth in the map.
