Web Maps are interactive maps that are accessed through web pages. Web maps support interactive features such as zooming in and out that require a live Internet connection. Using Mapping Toolbox™ software, you can:
Display web maps in a browser
Select the maps to display, called base
layers, including named base layers, such as
Street Map', and WMS Layers
Add vector data, called overlay layers, such as lines and markers
Share your results, using printing capabilities or
To display a web map using the toolbox, you must have an Internet connection. MathWorks cannot guarantee the stability and accuracy of web maps, as the servers are located on the Internet and are independent from MathWorks. Occasionally, maps may be slow to display, display partially, or fail to display, because web map servers can become unavailable for short periods of time.
As an example, the following figure shows the default web map
webmap function displays the map in
a browser that includes a pan and zoom controls. Also included is
an expander that you can use to display the Layer Manager. You can
use these tools to choose which base map layer to display, add overlay
layers to the map, and customize your view of the map. The toolbox
displays the web map in a browser window, not a MATLAB figure window.
The graphics in web maps are not part of MATLAB graphics.
The following figure shows the Layer Manager expanded.
When displaying named base layers, or a
WMSLayer array in a coordinate
reference system of EPSG:900913, the projected coordinate system is "Web Mercator".
Otherwise, when displaying a
WMSLayer array, the projected
coordinate system is EPSG:4326. These projections include a geographic quadrangle
bounded north and south by parallels (which map to horizontal lines) and east and
west by meridians (which map to vertical lines).
