This service was developed to act as the "Street" base map for the Montana Cadastral Mapping Application (http://gis.mt.gov/) and as the source for data overlay on the application's "Aerial" and "Topo" base maps.The map layers that are turned on by default are designed to combine to serve as a base map. The service contains a group of layers called Imagery Layers that are designed to act as a base map overaly for aerial imagery.The primary focus of the map is land ownership both public and private and displays such with different degrees of generalization depending on the level one zooms into the map. Similar to the depiction of land ownership it also displays transportation, hydrography, placenames and other common data usually found on a basemap at progressively larger scales as a user zooms in. It generally uses data from the Montana Spatial Data Infrastructure however in many cases the data are a custom subset of those themes designed to display at specific zoom levels.The following is a list of the layers in the service:Layer: Political Entities (0)
Description: This layer group contains Montana's counties and Indian reservations and locations of the county seats and 259 other towns. Layer: MT_Cities (1)
Description: This layer shows a point location and a name for 259 Montana towns. It does not include the county seats, which are shown in separate layer. Layer: Countyseat Symbol (2)
Description: This layer shows the locations and names of Montana's county seats. Layer: County Seat No Symbol (3)
Description: This layer shows the names of Montana's county seats. It is drawn at large scales where the street pattern reveals the town locations and point symbols are not needed. Layer: CountyLines (4)
Description: This layer shows Montana's county boundary lines. For more information and links to access the data, please see http://msl.mt.gov/GIS/BoundariesLayer: MT Reservations_Bndy (5)
Description: This layer shows the names and the outer boundaries of Montana's Indian Reservations. Layer: Counties (6)
Description: This is a polygon layer that is used to create dynamic labels for the county names. For more information and links to access the data, please see http://msl.mt.gov/GIS/BoundariesLayer: PLSS (7)
Description: This layer group contains Montana's Public Land Survey System. For more information and links to access the data, please see http://msl.mt.gov/GIS/PLSS
Layer: PLSS Township (8)

Description: This layer shows the boundaries and numbers of Montana's public land survey sections. For more information and links to access the data, please see http://msl.mt.gov/GIS/PLSSLayer: Transportation (10)
Description: This layer group shows Montana's railroads and roads. Layer: Primary Railroad Routes (11)Layer: PrimaryRoads (12)
Description: This layer is intended for display of selected major highways of Montana at small scales. Layer: PrimaryRoads_Mid_Range (13)

Description: This layer is intended for detailed display of Montana's Interstate, Primary, and Secondary highways at large scales. Layer: Web_Roads_PrimaryRural (15)
Description: These are selected major roads, not on Montana's highway system, for display at medium scales. Layer: Roads_cadastral (16)
Description: These are all of Montana's roads, other than the highway system, for display at large scales. Layer: Imagery Layers (17)
Description: The layers in this group are intended to be displayed as an overlay to aerial photographs, satellite images, or scanned topographic maps. Some of the layers are duplicates of other layers in the map service but with different symbology, others are included here as a convenience, so that all other groups may be turned off and this one may be turned on when an imagery layer is present. Layer: PrimaryRoads (18)
Description: This layer is intended for display of selected major highways of Montana at small scales. The symbology is modified for display with aerial or satellite imagery. Layer: PrimaryRoads_Mid_Range (19)
Description: This layer is intended for display of Montana's primary highways at medium scales. The symbology is modified for display with aerial or satellite imagery. Layer: Highways_cadastral (20)
Description: This layer is intended for detailed display of Montana's Interstate, Primary, and Secondary highways at large scales. Layer: Web_Roads_PrimaryRural (21)
Description: These are selected major roads, not on Montana's highway system, for display at medium scales. Layer: Roads_cadastral (22)
Description: These are all of Montana's roads, other than the highway system, for display at large scales. Layer: OwnerParcel (23)
Description: This layer is Montana's cadastral parcel database, with selected information from the Montana Department of Revenue property tax database. For more information about the data and links for access to the data, please see http://msl.mt.gov/GIS/Cadastral. The symbology is modified for display with aerial imagery or scanned topographic maps. Layer: Hydrography (24)
Description: This is a group layer for display of lakes and streams.Layer: Cadastral Lakes (25)
