The USGS has developed many tools and techniques for analyzing data and specialized websites for sharing information and products with the public.
Is the federal government responsible for updating geographic names on non-federal map products? Is the federal government responsible for updating geographic names on non-federal map products?
The U.S. Board on Geographic Names (BGN) is the official source for geographic names for federal use within the United States. The Geographic Names Information System (GNIS) contains geographic names for official use. The BGN, USGS, and GNIS are not responsible for how this information is used, updated, released, or otherwise is managed by end users. Questions about the use, update, or release of...

Does Geographic Names Information System (GNIS) include manmade and administrative features, such as churches, cemeteries, parks, schools, shopping centers, trails? Does Geographic Names Information System (GNIS) include manmade and administrative features, such as churches, cemeteries, parks, schools, shopping centers, trails?
No. GNIS does not include roads, highways, administrative, or cultural features, except for canals, channels, reservoirs, communities, civil divisions, and military features. In 2021 the following geographic features, referred to as “administrative” (cultural or man-made), were removed from GNIS: airport, bridge, building, cemetery, church, dam, forest, harbor, hospital, mine, oilfield, park, post...
What is The National Map Structures Tint? What is The National Map Structures Tint?
The National Map’s Structures Tint dataset represents manmade structures using broad-area tints rather than defining the exact shape of individual buildings. The Structures Tint data was provided by Oak Ridge National Labs and the Federal Emergency Management Agency. This dataset was introduced in 2021 and is designed for use at the 1:24,000 scale (the standard scale for USGS topographic maps) or...
Does the Latest Earthquakes map show non-earthquake seismic events? Does the Latest Earthquakes map show non-earthquake seismic events?
In addition to naturally occurring earthquakes, human activities such as mining and construction blasts can sometimes produce seismic waves large enough to be detected on the USGS national seismic network. These artificially-generated events have a different seismic ‘fingerprint’ from tectonic earthquakes, so they can be discerned by a seismologist when reviewed. Specifically, small quarry blasts...
Does the USGS have photographs of features in Antarctica? Does the USGS have photographs of features in Antarctica?
The USGS does not have a comprehensive photographic collection of geographic features in Antarctica. However, some air photography is available through EarthExplorer by searching the Antarctic Single Frames category within the larger Aerial Imagery category. A limited number of photographs taken on the ground are in the online USGS Denver Library Photographic Collection (be sure to click the...
How do I download layers in The National Map Viewer? How do I download layers in The National Map Viewer?
Base map data layers in The National Map Viewer are for viewing only. This application is designed for visualizing data, combining different data layers, and creating (and printing) your own maps. To download data from The National Map, see the link at the top of the Viewer for the Data Downloader. None of the base map layers in the Viewer are available for download, but some of them can be...
How do you determine the place name for an earthquake? How do you determine the place name for an earthquake?
For the automated naming of earthquakes we use a GeoNames dataset to reference populated places that are in close proximity to a seismic event. GeoNames has compiled a list of cities in the United States where the population is 1,000 or greater (cities1000.txt). This is the primary list that we use when selecting nearby places. In order to provide the public with a better understanding for the...
How should I cite datasets and services from The National Map? How should I cite datasets and services from The National Map?
The USGS does not require a specific format when citing data obtained through The National Map. You should follow the citation guidelines provided by instructors or publication editors as appropriate. The following should help you find the information that you need: Citation for Datasets Author: U.S. Geological Survey Release date: the first four numbers of from dataset metadata for the...
What are the differences between data, a dataset, and a database? What are the differences between data, a dataset, and a database?
Data are observations or measurements (unprocessed or processed) represented as text, numbers, or multimedia. A dataset is a structured collection of data generally associated with a unique body of work. A database is an organized collection of data stored as multiple datasets. Those datasets are generally stored and accessed electronically from a computer system that allows the data to be easily...
Where can I find metadata for USGS products? Where can I find metadata for USGS products?
Metadata links are included with all individual files listed in our Science Data Catalog. USGS data that predate 2000 might not have metadata. Metadata for Publications Metadata for publications (bibliographic information) authored by USGS scientists are in the USGS Publications Warehouse. Metadata for The National Map Products and Services In The National Map Viewer, click on the "Layer List"...
When/Why does the USGS publish research results in outside journals that require a fee to access rather than in the USGS publication series? When/Why does the USGS publish research results in outside journals that require a fee to access rather than in the USGS publication series?
Publishing in outside journals by USGS scientists allows the research—including its scientific and practical contributions—to be disseminated to others in a particular field. This makes scientific researchers and practitioners with similar interests aware of new knowledge in their field, and it helps to advance knowledge and its application. USGS scientists publish in both free open-access...
