Help Center Help Center. A Map object is a data structure that allows you to retrieve values using a corresponding key. Keys can be real numbers or character vectors. As a map matlab, they provide more flexibility for data access than array indices, which must be positive integers.

You can visualize your data in a geographic context, build map displays from more than 60 map projections, and transform data from a variety of sources into a consistent geographic coordinate system. Mapping Toolbox supports a complete workflow for managing geographic data. You can import vector and raster data from a wide range of file formats and web map servers. The toolbox lets you process and customize data using trimming, interpolation, resampling, coordinate transformations, and other techniques. Data can be combined with base map layers from multiple sources in a single map display.

Keys corresponding to values to return from the Map object, specified as a cell array. Even when you specify keys as strings, the keys must be contained in a cell array.

This example illustrates how to import geographic data with coordinates in latitude and longitude, display geographic data in a map display, and customize the display. This example imports polygon geographic vector data from a shapefile. Vertices in a shapefile can be either in geographic coordinates latitude and longitude or in a projected coordinate reference system. Read USA state boundaries from the usastatehi. The state boundaries are in latitude and longitude. Display the polygon geographic vector data onto an axesm -based map previously referred to as map axes. Since the geographic extent is in the United States, you can use usamap to set up the map.

Keys and values can be of any data type, providing more flexibility for data access than array indices and improved performance. Map because it supports more data types as keys and values and provides better performance. Use dictionaries to store key-value pairs of different data types.
