This example shows how to use the Mapping Toolbox to create a world map. Geospatial data can be voluminous, complex, and difficult to process. Mapping Toolbox functions handle many of the details of loading and displaying geospatial data, and use built-in data structures that facilitate data storage. Spatial data refers to data describing location, shape, and spatial relationships. Geospatial data is spatial data that is in some way georeferenced, or tied to specific locations on, under, or above the surface of a planet. Create an empty map axes, ready to hold the data of your choice. The function worldmap automatically selects a reasonable choice for your map projection and coordinate limits.
The player can intervene in the management menus and on the map, during meetings, and via responses to various alerts and requests. Differences with and improvements to the 2009 version of the Geo-Political Simulator: Rulers of Nations, Geopolitical Simulator 2, includes several new functions and improvements.
To display a world map, the function chose a Robinson projection centered on the prime meridian and the equator (0° latitude, 0° longitude). Create a new map axes for plotting data over Europe. This time, specify a return argument for the worldmap function to get a handle to the figure's axes.
The axes object on which map data is displayed is called a map axes. In addition to the graphics properties common to any MATLAB axes object, a map axes object contains additional properties covering map projection type, projection parameters, map limits, etc. The getm and setm functions and others allow you to access and modify these properties.
