Geospatial data

Geospatial data are explicitly defined across geographic space. Coordinates define where they belong.

The geospatial data landscape is complex and constantly evolving. The Map and Geospatial Hub is here to help you navigate that landscape to aid your research and other projects. Need to request geospatial data?

With ASU GeoData, you can discover and explore multiple forms of geographically-referenced data, including vector layers, maps, aerial photos, and more.

ASU GeoData shares the data, map, and imagery resources managed by the ASU Library Map and Geospatial Hub, but it also compiles and provides direct access to other organizations' geospatial data sites too, including data sites for major ASU research initiatives and various government agencies in Arizona.

 


AZGeo Data

AZGeo Data Hub is a cooperative data platform project sponsored by the Arizona Geographic Information Council (AGIC). AZGeo is hosted by the Arizona State Land Department and staffed by the Arizona Land Resources Information System (ALRIS).

 

 


 

LiDAR (Light Detection and Ranging)

LiDAR (Light Detection and Ranging) is a remote sensing method that involves shooting pulses of light to determine ranges (distances) of objects. Raw LiDAR data come in the form of dense point clouds. Derived LiDAR products include a wide range of three-dimensional data outputs, including digital surface, terrain, and other extracted features.

Metro Phoenix LiDAR Data

LiDAR and LiDAR-derived data initially acquired in 2014 from the USGS. Data were pre-released to ASU for public consumption in 2017.

The USGS Metro Phoenix LiDAR Data Index provides an interactive web map for viewing the available data. Information about the index layers and tiles can be found in the Details tab of the web map. Please use the Map and Geospatial Hub Service Request form to request LiDAR data. More information about the data can also be found here.


OpenTopography

The OpenTopography project facilities community access to high-resolution, Earth science-oriented topography data and related tools and resources. It is one of the largest open access repositories of LiDAR data in existence.

Users can access both raw (point cloud) and derived (raster) surface layers for various regions, as well as generate lower-resolution digital elevation model data from other sources (e.g., SRTM) for the same region on the fly.
