AddressPoints is a statewide dataset that contains address point data from all 29 Utah Counties. This dataset is a work in progress and some counties are more complete than others. One person in each county has been identified as the Master Address List (MAL) Authority to eliminate duplication of address point data and clarify the main person of contact. AGRC is working with each MAL Authority to continually improve this data and work toward quarterly updates.

The Address Points dataset shows Utah address points for all twenty-nine Utah counties. An address point represents a geographic location that has been assigned a US Postal Service (USPS) address by the local address authority (i.e., county or municipality) but does not necessarily receive mail. Address points may include several pieces of information about the structure or location that’s being mapped, such as:the full address (i.e., the USPS mailing address, if the address is for a physical location [rather than a PO box]);the landmark name; whether the location is a building;the type of unit;the city and ZIP code; unique code identifiers of the specific geographic location, including the Federal Information Processing Standard Publication (FIPS) county code and the US National Grid (USNG) spatial address;the address source; andthe date that the address point was loaded into the map layer.This dataset is mapping grade; it is a framework layer that receives regular updates. As with all our datasets, the Utah Geospatial Resource Center (UGRC) works to ensure the quality and accuracy of our data to the best of our abilities. Maintaining the dataset is now an ongoing effort between UGRC, counties, and municipalities. Specifically, UGRC works with each county or municipality’s Master Address List (MAL) authority to continually improve the address point data. Counties have been placed on an update schedule depending on the rate of new development and change within them. Populous counties, such as Weber, Davis, Salt Lake, Utah, and Washington, are more complete and are updated monthly, while rural or less populous counties may be updated quarterly or every six months.The information in the Address Points dataset was originally compiled by Utah counties and municipalities and was aggregated by UGRC for the MAL grant initiative in 2012. The purpose of this initiative was to make sure that all state entities were using the same verified, accurate county and municipal address information. Since 2012, more data has been added to the Address Points GIS data and is used for geocoding, 911 response, and analysis and planning purposes. The Address Point data is also used as reference data for the api.mapserv.utah.gov geocoding endpoint, and you can find the address points in many web mapping applications. This dataset is updated monthly and can also be found at: https://gis.utah.gov/data/location/address-data/.

Update information can be found within the layer’s attributes and in a table on the Utah Parcel Data webpage under Basic Parcels."Database containing parcel boundary, parcel identifier, parcel address, owner type, and county recorder contact information" - HB113. The intent of the bill was to not include any attributes that the counties rely on for data sales. If you want other attributes associated with the parcels you need to contact the county recorder.Users should be aware the owner type field 'OWN_TYPE' in the parcel polygons is a very generalized ownership type (Federal, Private, State, Tribal). It is populated with the value of the 'OWNER' field where the parcel's centroid intersects the CADASTRE.LandOwnership polygon layer.This dataset is a snapshot in time and may not be the most current. For the most current data contact the county recorder.

Salt Lake County Municipal Boundaries, including Cities, Metro Townships and Unincorporated areas.

Geospatial data about Salt Lake County, Utah Waterways. Export to CAD, GIS, PDF, CSV and access via API.

This dataset represents current county boundaries in Utah at 1:24,000 scale. Includes changes to the Salt Lake & Utah Counties (Draper Ridgeline) in 2005, changes to the Emery & Grand Counties (Green River) in 2002, and changes to Salt Lake & Davis Counties (NSL exchange). Potable, secondary, and supply water estimates for 2015 were joined to the county polygons by the Utah Division of Water Resources (April 2018).

NOTE: This dataset holds 'static' data that we don't expect to change. We have removed it from the SDE database and placed it in ArcGIS Online, but it is still considered part of the SGID and shared on opendata.gis.utah.gov.

This datasets contain a statewide coverage of contours.

• 500 foot contours derived from the 10 meter National Elevation Dataset’s (NED) Digital Elevation Model (DEM).

• 2 meter contours derived from 2 meter LiDAR for Salt Lake County. No smoothing has been applied to the contour data but a ‘Smooth Line’ in ArcMap with a ’50 meter Smoothing Tolerance’ cleans the data up nicely. Although the data is refered to as 2 meter, the contour intervals are .5 meter. SLCo_2m_Index is a shapefile that can be used to determine what files to download. These contour shapefiles cover 4,000 X 4,000 meter blocks. This data has a UTM NAD83 meters projection.

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). This file is georeferenced to the earth's surface using the Universal Transverse Mercator, Zone 12, Meters, North American Datum 1983(NAD83), projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000. The Vertical Datum of this data set is North American Vertical Datum 1988 (NAVD88). The specifications for the vertical control of DFIRM data files are consistent with those required for mapping at a vertical accuracy of 2.4 feet or better.
