This EnviroAtlas dataset shows the Salt Lake City, UT EnviroAtlas community boundary. It represents the outside edge of all the block groups included in the EnviroAtlas Community. This dataset was produced by 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).

Elementary School Boundaries in Salt Lake City.

This dataset represents an ongoing effort to approximate the geographic extents of 5 digit zip codes. The dataset was produced using a combination of methods and is based on several sets of source data. Methods include: 1) using local zip code polygon data obtained from counties and cities contained within these counties; 2) Identifying place locations (city, town, places) from the postal service website and address information system (AIS) and as a last result, building theissen polygons around usps places in unpopulated areas; and 3) editing line work using the 2000 Census TIGER line file's zip code attributes. In addition, AGRC has used the locations of mailing addresses known to be valid to fine tune this dataset.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Face refers to the areal (polygon) topological primitives that make up MTDB. A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face. The Topological Faces Shapefile contains the attributes of each topological primitive face. Each face has a unique topological face identifier (TFID) value. Each face in the shapefile includes the key geographic area codes for all geographic areas for which the Census Bureau tabulates data for both the 2020 Census and the annual estimates and surveys. The geometries of each of these geographic areas can then be built by dissolving the face geometries on the appropriate key geographic area codes in the Topological Faces Shapefile.

The physical location of an interagency, regional operation center for the effective coordination, mobilization and demobilization of emergency management resources. A coordination center serves federal, state and local wildland fire agencies through logistical coordination of resources throughout the geographic area, and with other geographic areas, as well.

The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The Eastern Great Basin Province is located in western Utah, eastern Nevada, southern Idaho, and the northwest corner of Arizona, encompassing all or parts of Mohave County in Arizona, Power, Bannock, Cassia, Oneida, and Franklin Counties in Idaho, Elko, Eureka, Lander, White Pine, Nye, Lincoln, and Clark Counties in Nevada, and Cache, Box Elder, Weber, Davis, Tooele, Salt Lake, Wasatch, Utah, Juab, Sanpete, Millard, Sevier, Beaver, Piute, Iron, and Washington Counties in Utah. The main population centers within the study area are Henderson and Las Vegas, Nevada.; Provo and Salt Lake City, Utah. The main highways, I-80, U.S. 6 and U.S. 50, generally traverse the area from east to west; I-15 travels northeast/southwest on the eastern portion of Eastern Great Basin from Salt Lake City, Utah to Las Vegas, Nevada. The Sevier River, Humboldt River, and Colorado River and their tributaries drain the area. The province boundary was drawn to include the geologic structures generally considered to be in or bounding the eastern portion of the Great Basin.
