Arizona Memory Project (AMP) – A Service of Arizona State Library

AMP is a service of the Arizona State Library. It comprises hundreds of collections and has amassed over 85,000 digital products. Historic maps make up a small but important minority of artifacts.

Historic Arizona County Road Maps is probably their most map-centric collection. The collection hosts 154 maps dating from 1880 to 1937. The oldest map is of a nascent Cochise County, 1880. Gila County offers its own map collections with 53 map artifacts.

AZGS’s own Arizona Mines collection broadcasts some historic mine maps.

Arizona State Land Department (ASLD)

ASLD provides a marvelous interactive map with more than 10 major layers: transportation, hydrography, surface beneficiaries, surface and mineral parcels, land ownership and more. The interactive map provides a suite of tools for querying, identifying, and measuring parcel data.

Arizona State Cartographers Office (SCO)

SCO provides the portal to the AZMAP NAIP orthophoto imagery for Arizona for 2010 and 2007. NAIP, or the National Agriculture Image Program, is a product of the U.S. Department of Agriculture. SCO also hosts the portal to GIS data of the Arizona Geographic Information Council.

Arizona Regional Image Archive - ARIA (University of Arizona)

Volume of Digital Topographic Products & Satellite Imagery – 10,000+

Digital Map types – Topographic maps, Digital Elevation Maps (DEM), NAIP Photography, Orthophoto Quads

Digital Map Format – varies

Common Map Scales – varies

ARIA hosts thousands of Arizona-centric digital topographic products, orthophotographs, and satellite images, including Landsat MSS, TM, and ETM products.

Data format varies depending on the digital product. Some geospatial and satellite products require specialized image-processing or GIS software to open and process. Nonetheless, this may be the single richest site for Arizona digital map and satellite image products.
