Since Detailed and Simple Earth are built into JMP, these options work any time, without a network
connection. However, these images might not be all that you want, or they might not be detailed at the
resolution that you need. If this is the case, and if you have an Internet connection, you can connect to a
Web Map Service to retrieve a map image that meets your needs.
Maps from the Internet
The National Aeronautics and Space Administration (NASA) and other organizations provide map image
data using a protocol called Web Map Service (WMS). These maps have the advantage of showing the most
up-to-date geographical information. However, the display of the maps can be slow depending on the
response time of the server, and the sites can change or disappear at any time. An Internet connection is
required to access the information.
