Abstract This service was developed to act as a general-purpose, multi-scale base map of Montana.It is similar to the base map used by the Montana Cadastral application (http://gisservicemt.gov/arcgis/rest/services/MSL/CadastralWebMerc/MapServer), but it includes additional layers for mountain peaks, wilderness, and state parks. At large scales, this service shows roads as double-line symbols, whereas the Cadastral base map always shows roads as single lines.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 overlay for aerial imagery.A major focus of the map is land ownership, both public and private. It displays ownership 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 some 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: MountainPeaks (0) Description: This layer shows the locations and names of 256 mountain peaks in Montana. Layer: Political Entities (1) Description: This layer group contains Montana's counties and Indian reservations and locations of the county seats and 276 other towns. Layer: MT_Cities (2) Description: This layer shows a point location and a name for 276 Montana towns. It does not include the county seats, which are shown in separate layer. Layer: Countyseat Symbol (3) Description: This layer shows the locations and names of Montana's county seats. Layer: County Seat No Symbol (4) 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 (5) 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 (6) Description: This layer shows the names and the outer boundaries of Montana's Indian Reservations.

Layer: Imagery Layers (23) Description: The layers in this group are intended to be displayed as an overlay to aerial photographs or satellite images. 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 (24) 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.
