What is a WMS server?
A Web Map Service (WMS) is a standard protocol developed by the Open Geospatial Consortium for serving georeferenced map images over the Internet. These images are typically produced by a map server from data provided by a GIS database.
Where to get a WMS server link
State or city agencies typically have WMS server links in the same website where the GIS data is available. They can also be easily found using the keywords “WMS server link” + “city name” in any search engine.
For example, the WMS server link for New York City is in the gis.ny.gov website.
