Data from WMS web services can be used to provide background layers for
your map. With WMS data, you take the data as it is; you cannot reproject it.
The number of Web Map Services (WMS) that implement OpenGIS interfaces
on the Internet is increasing all the time, as more organizations adopt the
open standards.
Once you have located some WMS data, determine the URL of the page that
serves the published layers. Often, this is not a standard web page that you
can open in a browser, but a page that has been programmed using a scripting
language such as CGI, PHP, or ASP. A typical web server address looks like
this:
http://wms.jpl.nasa.gov/wms.cgi
Paste the address into the Data Connect window in AutoCAD Map 3D.
NOTE Websites that host web services appear and disappear or are under
construction. Not all sites that you find will work perfectly (or at all).
You can also bring in web-based feature data (page 346).
