This web map contains the ESRI ArcGIS Online World Topographic Map service, (aka "the community basemap"). The World Topographic Map service is designed to be used as a basemap by GIS professionals and as a reference map by anyone. The service includes administrative boundaries, cities, water features, physiographic features, parks, landmarks, highways, roads, railways, airports, and buildings overlaid on land cover and s

This map presents land cover and detailed topographic maps for the United States. It uses the USA Topographic Map service. The map includes the National Park Service (NPS) Natural Earth physical map at 1.24km per pixel for the world at small scales, i-cubed eTOPO 1:250,000-scale maps for the contiguous United States at medium scales, and National Geographic TOPO! 1:100,000 and 1:24,000-scale maps (1:250,000 and 1:63,000 in Alaska) for the United States at large scales. The TOPO! maps are seamless, scanned images of United States Geological Survey (USGS) paper topographic maps.

The WyGISC Imagery Server provides access to the most recent aerial photography 2009 true-color NAIP and all previous aerial photography collected, i.e. 2006, 2000, and 1994, Additionally access is provided for all series (i.e. 1:24,000, 1:100,000, and 1:250,000) of Digital Raster Graphics (scanned topographic maps) for Wyoming, including both collared and clipped images.
A DRG is a raster image of a published map. DRG's are made by scanning published paper maps on high-resolution scanners. The raster image is georeferenced and fit to the Universal Transverse Mercator (UTM) projection, and NAD 1927 Datum. Colors are standardized to remove scanner limitations and artifacts. The average data set size is about 8 megabytes in Tagged Image File Format (TIFF) with PackBits compression. DRG's can be easily combined with other digital cartographic products such as digital elevation models (DEM) and digital orthophoto quadrangles (DOQ). DRGs are available for Wyoming at 1:24,000, 1:100,000, and 1:250,000.

This ArcGIS Server serviceDRGs (Digital Raster Graphics), or topos (USGS Topographic Maps) provides a cached service for users of Wyoming geospatial data using ESRI GIS. The service provides scale-dependant representation of the 250,000, 100,000, and 24,000 topos for Wyoming. USE CONSTRAINTS: Users should follow use constraints found for each data layer available in the mapping service. Visit the Wyoming GeoLibrary for original metadata. WYGISC DOES NOT GUARANTEE 24/7 SUPPORT OF ITS UNFUNDED, FREE MAPPING SERVICES. WyGISC reserves the right to remove access to these services at any time.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This Digital Raster Graphic (DRG) was created using scanned U.S. Geological Survey 7.5-minute 1 to 24,000 scale maps georeferenced in Universal Transverse Mercator (UTM) grid. DRGs can be acquired with or without collar information for use in Geographic Information System (GIS) environment. Collarless DRGs can be edge matched creating a continuous collection of topographic maps.
