This map service shows a static map image designed for display at approximately 1:100,000 scale. The map includes public land ownership, selected federal and state managed areas, lakes, streams, roads, the Public Land Survey system, 50-foot contours, shaded relief, and selected buildings and structures. The map was produced by the Montana State Library with the latest data that was available in January 2016. The map legend for the service is available at http://ftp.geoinfo.msl.mt.gov/Documents/Metadata/Reference100k.tif.The service is in the Web Mercator coordinate system. This coordinate system distorts the scale of maps of Montana so that everthing appears to be about 40 percent larger than it really is. Any use of this service for making measurements must be done with software that understands the scale distortion. This typically includes on-line mapping serivces but does NOT include desktop mapping applications such as ArcGIS Destktop.The map is also available as a statewide MrSID image in Montana State Plane Coordinates and as individual 60x30-minute quadrangle MrSID images.
