WMS Services for GIS Software

WMS services are set up to provide access to air photos and other grid-cell data without users having to download and store large files on their own computers. The services are intended primarily for people using geographic information systems (GIS) software. Click here for instructions on connecting to a service using several commonly used GIS software packages.
