Data Acquisition


ArcGIS Streaming Basemap


ESRI Add Basemap provides a series of streaming basemaps from the Representational State Transfer Server or a ReST server. Basically, a ReST server is a hard drive owned by someone else, in this case ESRI, where large amounts of data are stored and access is provided via the internet to those with authorization. This data is often too large to download or may take up an unnecessarily large amount of your personal hard drive.

While Add Basemap File Menu ESRI has quite a lot of data on their ReST server that can be accessed through the Catalog window in ArcMap (not by default, by the way, so don’t go looking for it), the most used basemaps are available for use through the File menu in ArcMap.

Other ArcGIS Online Data


ArcGIS Online data (also found in the File menu) is a good source for both raster and vector data. Layers of all kinds can be found by searching the database using key terms like “rivers Colorado” or “population Arizona”. The search may no produce perfect results, but since you know how to extract data from larger datasets, it might be just what you need.

USGS Earth Explorer


“The EarthExplorer (http://earthexplorer.usgs.gov/) user interface is an online search, discovery, and ordering tool developed by the United States Geological Survey (USGS). EarthExplorer supports the searching of satellite, aircraft, and other remote sensing inventories through interactive and textual-based query capabilities. Through the interface, users can identify search areas, datasets, and display metadata, browse and integrated visual services within the interface.”

USGS Global Visualization (GloVis) Viewer


“The USGS Global Visualization Viewer (GloVis http://glovis.usgs.gov/ - requires a Java enable browser) is a quick and easy online search and order tool for selected satellite and aerial data. The viewer allows user-friendly access to browse images from the multiple EROS data holdings. Through a graphic map display, the user can select any area of interest and immediately view all available browse images within the USGS inventory for the specified location. From the browse image viewer page, the user may either navigate to view adjacent scene locations or select a new area of interest. GloVis also offers additional features such as cloud cover limits, date limits, user-specified map layer displays, scene list maintenance, and access to metadata. An ordering interface is provided for data that have processing options available. A downloading interface is provided for datasets that are available at no charge.”

The National Map


“As one of the cornerstones of the U.S. Geological Survey’s (USGS) National Geospatial Program, The National Map (http://nationalmap.gov/) is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data. The geographic information available from The National Map includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover.”

NRCS Geospatial Data Gateway


“The Geospatial Data Gateway (GDG - https://gdg.sc.egov.usda.gov/) provides access to a map library of over 100 high resolution vector and raster layers in the Geospatial Data Warehouse. It is the One Stop Source for environmental and natural resources data, at anytime, from anywhere, to anyone. It allows you to choose your area of interest, browse and select data, customize the format, then download or have it shipped on media.”

USGS Geological Data


“The National Geologic Map Database (NGMDB - http://ngmdb.usgs.gov/maps/MapView/)is a Congressionally mandated project led by the U.S. Geological Survey and Association of American State Geologists. The purpose is to build a national archive of standardized geologic map information. This national archive is “virtual” – you can access it through a searchable catalog that contains information on over 88,000 geoscience maps and reports dating back to the 1800’s, with links to hundreds of publishers.”

University of Minnesota - National Historic Geographic Information System


“The National Historical Geographic Information System (NHGIS - https://nhgis.org/) provides, free of charge, aggregate census data and GIS-compatible boundary files for the United States between 1790 and 2014. A good place to get US Census and American Community Survey data. It has the virtue of putting gisjoin fields into their data files and shapefiles, which makes joining the data easier.”

Public Land Survey System (PLSS) CadNSDI Data

“The Public Land Survey System (PLSS) is a way of subdividing and describing land in the United States. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior, Bureau of Land Management (BLM).

BLM Cadastral Survey, the FGDC Cadastral Subcommittee, Premier Data Services, and Fairview Industries, have teamed over the past four years to complete the standardized PLSS data for nearly all of the 30 Public Domain states.”

The GIS Directory operated by the Department of Local Affairs (DOLA) (http://dola.colorado.gov/gis-cms/content/gis-resources) is a geospatial search engine for locating Colorado specific data. Using a search term, the database will return a series of resources that meet the criteria.

Colorado State Geospatial Centroid


The Colorado State Geospatial Centroid geospatial data list (http://gis.colostate.edu/data.aspx) provides links to commonly used data sets for Colorado. While this list references other sources, it’s a simple interface with clear and concise labels for finding generalized data sets from which you can extract smaller data sets.

Bureau of Land Management Colorado


“In the business of managing public lands, the BLM collects and utilizes a great deal of information related to or describing a piece of land and the resources on and under it. Data might be information about bird nesting sites or wild horse herd use areas. It might be legal land survey information or legal descriptions of land parcels. The common thread is that this information is tied to the land” (http://www.blm.gov/co/st/en/BLM_Programs/geographical_sciences/gis/GeospatialData.html)

Colorado Department of Natural Resources Division of Water Resources


“The Colorado Division of Water Resources (DWR), also known as the Office of the State Engineer, administers water rights, issues water well permits, represents Colorado in interstate water compact proceedings, monitors streamflow and water use, approves construction and repair of dams and performs dam safety inspections, issues licenses for well drillers and assures the safe and proper construction of water wells, and maintains numerous databases of Colorado water information. ”
