State Geographic Information Datasource


What is the SGID

Established by State law in 1991, Utah's State Geographic Information Datasource (SGID) provides a centralized collection of hundreds of GIS data layers developed, aggregated, or acquired by the State. Evolving technologies have allowed us to transform the SGID from a single database to a broad collection of data resources under the SGID umbrella. It contains both UGRC-curated datasets and references to data from a wide variety of state and local agencies. Many resources have both download links and links to web services for direct consumption.

There are many facets, or parts, to the SGID today, with each one addressing specific audiences and technologies. Every facet is organized by SGID data categories. When you know the category of the data you want to use, you can find it in the SGID. Read the following sections to figure out which SGID technology is right for you.

Choosing the right SGID technology

With so many ways to access SGID Data, how do you you know which one to use? We created a guide to help you understand the best ways to access the data based on your use case.

Browsing for data

Desktop mapping (ArcGIS, QGIS, etc)

ArcGIS Online webmaps and storymaps

Custom web app development

Geocoding Addresses

The SGID Index

The SGID Index is the primary source of information for SGID datasets. It includes links to detailed product pages about UGRC-maintained datasets as well as direct links to the authoritative sources for datasets served by other state agencies. The index lists the resource's category, name, and primary data steward, along with a short description of the resource and links to web services (if available). Contact us if you would like your data to be included in the SGID Index.

The Open SGID database

The Open SGID is a publicly available database containing our curated collection of GIS datasets. You can use this vendor-neutral database connection to directly access Utah spatial data in a wide variety of applications, including most GIS programs and common database clients, and programming languages. You can find the most up-to-date information about the Open SGID, including troubleshooting tips and an issue tracker, in the Open SGID GitHub repository , opens in a new tab . Please read, understand, and abide by the terms of use prior to connecting.

UGRC ArcGIS Online

UGRC uploads all the curated datasets to ArcGIS Online , opens in a new tab as hosted feature services. You can access them via their service URLs or directly in Esri products. The name of every SGID item in ArcGIS Online will start with "Utah" (i.e., "Utah Roads") and have an UGRC-branded thumbnail. They are also shared with a Utah SGID group that matches their category.

The UGRC ArcGIS Online organization also acts as the repository for "shelved" and "static" curated SGID datasets. These types of datasets are only available in ArcGIS Online as specified in our SGID Database policy. If you are looking for a specific year of data or a dataset that was replaced, start here.

These services are a great tool if you want to display the data in a web map, programmatically query for attributes or geometry in an application or script, or include the data in an analysis.

The SGID on ArcGIS is a single destination for ArcGIS Online GIS resources stewarded by multiple agencies with ArcGIS Online accounts. Each item in the Hub contains data download links along with web service links for consuming the datasets in web maps and other applications. We share all our curated datasets through the site and encourage other agencies and organizations to share their datasets with the SGID on ArcGIS as well to help spread GIS data to the widest possible audience.

The SGID on ArcGIS is the best place to download data. Every non-shelved ArcGIS Online service is catalogued in the SGID on ArcGIS.

Discover base maps and imagery

Discover complements the SGID vector GIS data with raster imagery and base maps. The base maps are created by UGRC's cartographers, and Discover serves them using WMS image and WMTS tiled image services that anyone can use in a wide variety of desktop and web applications. The Discover base maps are a beautiful reference layer for your daily GIS work, web maps, or printed media. The imagery is a valuable resource for artificial intelligence projects using computer vision to extract difficult to map information or comparing change from year to year.

Raster discovery app

The Raster discovery app allows users to search and download all of UGRC's raster datasets, including publicly-available imagery, elevation, lidar, and scanned maps. You can see the Discover base maps in the app as well as search for and download the tiles that cover your area of interest. If you need local copies of imagery, the Raster discovery app is the place to start.


UGRC's API is an http-enabled service for accessing this valuable geospatial data. From geocoding addresses against the most accurate statewide roads and address points dataset to querying any data layer in the Open SGID, the solutions created by the API are endless. The API powers UGRC’s components , opens in a new tab , Esri locator proxy service, and our API Client which can help you navigate the sea of data within the SGID.

Sharing with the SGID

The Utah State Geographic Information Datasource is one of the premier statewide GIS data resources in the country, providing clean, consistent, and authoritative data across every geography in the state. People have been turning to the SGID for nearly 30 years to support their personal, commercial, academic, and government projects.

Nearly all the data that make the SGID such a valuable resource come from cities, counties, and other state agencies. We offer a heartfelt Thank You! on behalf of both UGRC and all the users of the SGID to everyone who has contributed data.

We hope you'll follow the example of our current contributors and consider sharing your data with a broad audience through the SGID. We have three separate "tracks" to follow based on where your data fits best: the SGID Index, the SGID on ArcGIS, and the Open SGID. There's also a separate process for contributing to or updating an existing SGID dataset.
