Web Resources for GIS Datasets
GIS datasets are an important part of geographic information science today. Prior to the development and growth of the internet, GIS datasets used to be stored on CD-Roms. Today, they are accessible on various websites throughout the internet. Here are some links:
Data | ESRI
Esri provides a full spectrum of ready-to-use, high-quality geospatial data for your GIS visualization and analysis projects. Whether licensed from renowned, industry-leading providers or built with Esri's proven methodologies, we strive to deliver the most accurate and current data available.
Envirofacts | Environmental Protection Agency
This website provides access to several EPA databases to provide you with information about environmental activities that may affect air, water, and land anywhere in the United States.
EROS Data Center | USGS Includes aerial photographs from 1937 onward and satellite images. Links to EarthExplorer and Glovis to download shapefiles.
Since 2005 Geodata.gov has provided the largest web-based access at a single-point for maps, government data, and geospatial services - the Geospatial One Stop. Data.gov, launched in May 2009, provides access to over 400,000 (primarily geospatial) datasets from 172 agencies across the Federal government. On October 1, 2011, Geodata.gov moved to Geo.Data.gov, within the Data.gov infrastructure.
Geospatial Platform | Federal Geographic Data Committee
Federal agencies and their partners collect and manage large amounts of geospatial data - but these data are often not easily found when needed or accessible in useful forms. The Geospatial Platform provides ready access to federally maintained geospatial data, services and applications. The content of all datasets and services demarcated with the Data.gov globe have been verified by the Agency to be consistent with Federal privacy, national security, and information quality policies. As an additional service to our users, we also provide access to data from our partners across State, Tribal, Regional and local governments as well as non-governmental organizations.
GIS Data Depot
In order to access and download data GISDataDepot users are required to have a GeoCommunity account. Many data types of data (DEM, NWI, DLG, LU/LC, and TIGER) are available for free download (Green icon). Most other data products (DRG, DOQ, DOQQ, FEMA) will require account holders to purchase data "blocks" for a nominal fee using their account.
National Elevation Dataset
The National Elevation Dataset (NED) is the primary elevation data product of the USGS. The NED is a seamless dataset with the best available raster elevation data of the conterminous United States, Alaska, Hawaii, and territorial islands.
National Geodetic Survey | National Oceanic and Atmospheric Administration
The Mission of NOAA's National Geodetic Survey (NGS) is "to define, maintain and provide access to the National Spatial Reference System to meet our nation's economic, social, and environmental needs."
Natural Earth Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software.
TIGER Census Shapefile
The Census Bureau offers several file types and an application for mapping census geographic data based on data found in their MAF/TIGER database.
