World Countries is a detailed dataset of country level boundaries which can be used at both large and small scales. It has been designed to be used as a basemap and includes an additional Disputed Boundaries layer that can be used to edit boundaries to fit a users needs and view of the political world.

Included are attributes for local and official names and country codes, along with continent and display fields. Particularly useful are the Land_Type and Land_Rank fields which separate polygons based on their size. These attributes can be used for rendering at different scales by providing the ability to turn off small islands which may clutter small scale views.

World Countries Generalized represents generalized boundaries for the countries of the world as of August 2022. The generalized political boundaries improve draw performance and effectiveness at a global or continental level. This layer is best viewed out beyond a scale of 1:5,000,000.This layer's geography was developed by Esri and sourced from Garmin International, Inc., the U.S. Central Intelligence Agency (The World Factbook), and the National Geographic Society for use as a world basemap. It is updated annually as country names or significant borders change.

This polygon layer represents the ten USA and Mexico states addressed by the U.S.-Mexico Border Program. States are sourced from Esri's ArcGIS Online: USA States (Generalized) Living Atlas Layer: https://www.arcgis.com/home/item.html?id=99fd67933e754a1181cc755146be21ca These data support the U.S.-Mexico Border Program Map, which highlights the projects funded through the Border 2020 Program (2013-2020) in both Region 9 and Region 6 of the U.S. EPA, including U.S. Federally recognized Tribal communities and states of Texas, New Mexico, Chihuahua, Nuevo Leon, Tamaulipas, Coahuila, California, Baja California, Sonora, and Arizona within 62 miles (100 kilometers) of the U.S.-Mexico Border. The projects stem from the Border 2020 framework that has five goals to reduce air pollution, improve access to clean water, promote materials and waste management, improve emergency preparedness, and enhance environmental stewardship, and fundamental strategies that includes children's health and environmental education and outreach. This layer is tied to the U.S.-Mexico Border Program with EPA and is relevant to past and future programs.

This map layer portrays the State boundaries of the United States, Puerto Rico, and the U.S. Virgin Islands. The map layer was created by extracting county polygon features from the CENSUS 2006 TIGER/Line files produced by the U.S. Census Bureau. These files were then merged into a single file and county boundaries within States were removed. This is a revised version of the July 2012 map layer.The data and related materials are made available through Esri (http://www.esri.com) and are intended for educational purposes only (see Access and Use Constraints section).

Integrated terrain models covering 16,357 square kilometers of the Massachusetts coastal zone and offshore waters were built to provide a continuous elevation and bathymetry terrain model for ocean planning purposes. The area is divided into the following four geographical areas to reduce file size and facilitate publishing: Massachusetts Bay from the Massachusetts-New Hampshire border south to Provincetown and Scituate and east to Stellwagen Bank; Cape Cod Bay from Provincetown to Scituate and south to Hyannis; Buzzards Bay from the Cape Cod Canal southwest to the State border including the Elizabeth Islands and extending north to Fall River and Mount Hope Bay; and Nantucket and Vineyard Sounds, from Hyannis south to the border of the Massachusetts Coastal zone approximately 8 kilometers south of Nantucket. A Triangulated Irregular Network was created from public-domain bathymetric and LiDAR data using the ArcGIS terrain-model framework and then interpolated into a 32-bit GeoTiff of 10 meter resolution. The grids for each of the four geographical areas are referenced to the Universal Transverse Mercator, Zone 19, North American Datum of 1983 coordinate system, and the North American Vertical Datum of 1988. A polygon shapefile recording the source datasets accompanies each of the four grids.

Three feature layers of Unites States internal state boundaries at different scales: 1:500K, 1:5M, and 1:20M. These layers are intended for use as a cartographic product. It is up to the user to determine which layer is most appropriate for their map.Derived from 2019 US Census Bureau Cartographic Boundary Files for state boundaries using ArcGIS Pro 2.4.3. Process:Original files were downloaded from US Census for the three different scales.Polygons were then converted to lines using the Polygon-to-Line tool.To remove the coastlines, all rows not having a LEFT_FID or RIGHT_FID attribute equal to -1 were then exported to a new geodatabase feature class.The geodatabase was zipped and uploaded to ArcGIS Online.For more information on Cartographic Boundary Files visit https://www.census.gov/programs-surveys/geography/technical-documentation/naming-convention/cartographic-boundary-file.html and https://www.census.gov/geographies/mapping-files/time-series/geo/cartographic-boundary.html.Created by Ryan Davis (RDavis9@cdc.gov) on behalf of CDC/ATSDR/DTHHS/GRASP.

The North Carolina State and County Boundary vector polygon data provides location information for North Carolina State and County Boundary lines derived from the best available survey and/or Geographic Information System (GIS) data. Sources for information are the North Carolina Geodetic Survey (NCGS), NC Department of Transportation (NCDOT), United States Geological Survey (USGS), and field surveys conducted by licensed surveyors in North Carolina and neighboring states that have been approved and recorded in their respective counties. North Carolina Geodetic Survey assists counties on a cooperative basis (NC General Statute 153A-18) in defining and monumenting the location of uncertain or disputed boundaries as established by law. Some counties have completed boundary surveys for at least a portion of their county boundary. However, the majority of county boundaries have not been surveyed and are represented by the best currently available data from GIS sources, including NCDOT county maps (which originally came from the USGS) and updated county parcel maps.

This feature represents the entire area considered as the U.S.-Mexico border region for the U.S.-Mexico Border Program. The extent of the area was agreed upon between the United States and Mexico under the 1983 La Paz Agreement. The framework of this agreement stated that the border area is defined as "the area situated 62 miles (100 kilometers) on either side of the inland and maritime boundaries". This layer was generated by buffering the Homeland Infrastructure Foundation-Level Data (HIFLD) "Mexico and US Border" layer (https://hifld-geoplatform.opendata.arcgis.com/datasets/geoplatform::mexico-and-us-border/about) by [60] Miles. These data support the U.S.-Mexico Border Program Map, which highlights the projects funded through the U.S.-Mexico Border Program (2013-2020) in both Region 9 and Region 6 of the U.S. EPA, including U.S. Federally recognized Tribal communities and states of Texas, New Mexico, Chihuahua, Nuevo Leon, Tamaulipas, Coahuila, California, Baja California, Sonora, and Arizona within 62 miles (100 kilometers) of the U.S.-Mexico Border.
