City of Phoenix parcel boundaries and details are shown for use to provide the best readability when used with different basemaps or aerial photos. Not intended for surveying, legal or engineering purposes. For non-commercial purposes only! This data is updated monthly.

The City of Phoenix (COP) zoning boundaries were digitized from a hard copy data set, by contract, in 1991. Since that time, updates to the data have been made on an ongoing basis as land is rezoned. The layer is digitized at a relatively small scale, from approximately 1:10 to 1:10,000. Changes are made when inconsistencies are found.Contact Information: zoning@phoenix.gov

The Year 2000 Land Use coverage was created as a joint effort of MAG and MAG member agency staff. Land Use components were classified into 46 categories. The Year 2000 Land Use coverage is used for a variety of planning purposes including socioeconomic forecasting and air quality modeling.

The Historic Preservation Office (HPO) works to protect and enhance historic neighborhoods, buildings and sites in Phoenix. HPO works closely with the Historic Preservation Commission to identify and designate eligible properties and districts for listing on the Phoenix Historic Property Register. Protection is provided to designated properties through city review and approval of exterior alterations to buildings and demolition requests. HPO also administers the Historic Preservation Bond fund that supports a number of financial assistance programs for historic properties. Rehabilitation training and educational activities are offered to heighten public awareness and appreciation for the community's historic resources.Contact Information: historic@phoenix.gov

Parcel-level land-use data derived from Sanborn Fire Insurance Map coverage of Central Phoenix for 1900, 1915, 1949, 1963. This dataset traces urbanization in Central Phoenix from Phoenix’s pre-statehood settlement to postwar downtown development and change amid rapid urban growth.

This dataset contain the parcels from the Maricopa County Assessor's office. The area covered is in Maricopa County (Phoenix metro area), Arizona. Major cities include Phoenix, Scottsdale, Mesa and Tempe. Various types of property usage are depicted in this layer. The most common are residential, commercial, industrial and agricultural properties. Multiple sources were used to collect the information including but not limited to CAD packages, aerial photography, and digitizing from paper maps. Adjustments are made where necessary in the process of updating and some parcel lines are only approximate. In cases where a line adjustment might create a loss of landsize it is typically taken out from the right of way to minimize the loss of landsize in the property. The line symbology for different property lines are not available in this dataset. In addition to standard fields the data has unique assessor parcel number for identification, basic temporal information and the location of property.

The EnviroAtlas Phoenix, AZ Meter-Scale Urban Land Cover (MULC) data and map were generated from USDA NAIP (National Agricultural Imagery Program) four band (red, green, blue and near-infrared) aerial photography taken from June through September, 2010 at 1 m spatial resolution. Seven land cover classes were mapped: water, impervious surfaces, soil and barren land, trees and forest, shrubs, grass and herbaceous non-woody vegetation, and agriculture. An accuracy assessment using a completely random sampling of 598 land cover reference points yielded an overall user's accuracy (MAX) of 69.2% and an overall fuzzy user's accuracy of 75.4%. The area mapped includes the entirety of the Central Arizona-Phoenix Long-Term Ecological Research (CAP-LTER) area, which was classified by the Environmental Remote Sensing and Geoinformatics Lab (ERSG) at Arizona State University. The land cover dataset also includes an area of approximately 625 square kilometers which is located north of Phoenix. This section was classified by the EPA land cover classification team. This dataset was produced by the Environmental Remote Sensing and Geoinformatics Lab (ERSG) at Arizona State University and the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

This dataset has been created to meet the needs of the research community of Arizona State University. Apart from purely vizualization purposes (i.e. displaying the data on various maps) it can potentially be used for spatial modeling. The data consist of engineering-quality contours, also known as isolines, created from the NED 10-meter Digital Elevation Model subset to the extent somewhat exceeding Cetral Arizona - Phoenix LTER. Contours ( lines connecting points of equal height above sea level) are drawn at 15 meter intervals with the base set at 145 m of elevation. Contours are an exact interpretation of the grid surface model and may sometimes appear blocky looking, may cross, appear to intersect, or form an unclosed branching line. All these are valid engineering-quality interpretations of the elevation surface that cartographers typically modify (smooth) for aesthetic purposes.

The 1995 Land Use coverage was created as a joint effort of MAG (Maricopa Association of Governments) and MAG member agency staff. Land Use components were classified into 24 categories. The 1995 Land Use coverage is used for a variety of planning purposes including socioeconomic forecasting and air quality modeling.

Digitized zoning maps for three time points during Phoenix’s 20th Century development: 1930-1941 (Phoenix’s original adoption of zoning), 1955 (onset of postwar expansion), and 1970 (major annexation and planning for growth, including the city’s incorporation of large agricultural areas for urban expansion).

REQUIRED: A brief narrative summary of the data set.

Detailed land-cover mapping is essential for a range of research issues addressed by sustainability science, especially for questions posed of urban areas, such as those of the Central Arizona-Phoenix Long-Term Ecological Research (CAP LTER) program. This project provides a 1-meter land-cover mapping of the CAP LTER study area (greater Phoenix metropolitan area and surrounding Sonoran desert). The mapping is generated primarily using 2015 National Agriculture Imagery Program (NAIP) four-band data, with auxiliary GIS data used to improve accuracy. Auxiliary data include the 2015 cadastral parcel data, the 2014 USGS LiDAR data (1-meter), the 2014 Microsoft/OpenStreetMap Building Footprint data, the 2015 Street TIGER/Line, and a previous (2010) NAIP-based land-cover map of the study area (https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-cap&identifier=623). Among auxiliary data, building footprints and LiDAR data significantly improved the boundary detection of above-ground objects. Post-classification, manual editing was applied to minimize classification errors. As a result, the land-cover map achieves an overall accuracy of 94 per cent. The map contains eight land cover classes, including: (1) building, (2) asphalt, (3) bare soil and concrete, (4) tree and shrub, (5) grass, (6) water, (7) active cropland, and (8) fallow. When compared to the aforementioned, previous (2010) NAIP-based land-cover map for the study area, buildings and tree canopies are classified more accurately in this 2015 land-cover map.

The simplified classification of Maricopa Association of Governments (MAG) land use map is created by combining the original land use categories into 5 major classes - urban, agriculture, recreation, desert, and other. This has been done for land use/land cover monitoring purposes and to compare the 2000 land use map with historic land use layers including the 1995 MAG land use map.

This is the digitized version of a map of the Hohokam canal system in what is now the Phoenix metropolitan area. It is based on the thesis research by J. B. Howard (Howard, J. (1990). Paleohydraulics : techniques for modeling the operation and growth of prehistoric canal systems. Thesis (M.A.)--Arizona State University, 1990). The original paper map is based on previous archaeological data, overlayed onto USGS 7.5 minute quadrangle maps to recreate the canal pattern.
