What Is Web Mapping Service?
The Web Mapping Service (WMS) provides access to a georeferenced representation of the data for basic mapping and data visualization applications. A Geographic Information System (GIS) software application or online mapping tool that supports WMS is required for viewing the georeferenced data from the WMS server.
The WMS link provides access to data by connecting to a server over the Internet without having to download large files on your computer.
