Web mapping is the process of using the maps delivered by geographic information systems (GIS) in a web browser. Web Maps allow the viewer to choose which layers in the table of contents can be overlayed over one another. Feature layer information on one or more layers can be found by pointing and clicking on the map, or by performing queries on a layer.
There are also a number of Tools found in the web map. These allow the user to mark or highlight locations on the map, measure distance and area, plot coordinates, and download spatial datasets. You can also upload your own spatial data to create spatial overlays with the data available in the web map. Navigation tools are provided to allow the viewer to pan and zoom around the map, Print tools are provided to print map areas on the screen at a scale and with a legend.
You can also find our web map viewers under "Applications" on our Resources page.
