GIS Data and Applications: GIS and Map Data

widely-used historical climate database: Soil-Water Balance , SRTM digital elevation, Evapo-Transpiration and Global Aridity

a large amount of land use data collection by the United State Geological Survey worldwide

Open Source European geographic information, infrastructure. Have to join (free) and request data.

The Food & Agriculture Organization (FAO) GeoNetwork provides Internet access to interactive maps, satellite imagery. Its hard to find open data, but there are some spatial databases.

Access various GIS datasets, including gridded data for climate and land use. Datasets can be subsetted or summarized before download using several algorithms, and these algorithms can also be applied to other datasets hosted elsewhere.

The GEO portal is a gateway to global Earth Observation data, information, and services developed by the European Space Agency (ESA)and the Food and Agriculture Organization of the United Nations (FAO) as part of a set of contributiona to the Global Earth Observation System of Systems (GEOSS).

Geospatial informationfor addressing global challenges. Raster elevation, Vegetation, Land use, and Land cover are available. Vector data is harder to find.

Map Library is a source of public domain basic map data concerning administrative boundaries in Africa. Formats available are: Map Maker DRA, ESRI Shape file, MapInfo MIF, and GoogleEarth KMZ.

A public domain map dataset. Includes cultural vectors such as administrative boundaries (countries), as well as physical vectors. Raster files include: shaded relief, bathymetry (ocean-depth), and natural earth. Nice interface.

files extracted from the OpenStreetMap [ www.openstreetmap.org ] project, an open source Wikipedia-like resource. Note that these are huge data sets; data is crowd-sourced and not necessarily accurate

Search satellite images, aerial photographs, elevation data and cartographic products from several sources. Includes data from the Landsat missions and a variety of other data providers.

Free climate data for ecological modeling and GIS, generated from average monthly climate data from weather stations, variable include precipitation, temperature, and bioclimatic variables.

The EDG is a gateway for searching for geospatial and non-geospatial data resources made available by EPA's Program Offices, Regions, and Laboratories. At the core of the EDG is the metadata catalog, a repository containing metadata records describing the information resources.

The EPA collects information about facilities or sites subject to environmental regulation. The EPA Geospatial Data Access Project provides downloadable files of these facilities or sites in the following formats: Extensible Markup Language (XML), Keyhole Markup Language (KML), ESRI Geodatabase, and Comma Separated Value (CSV).

the US govt open data source for all kinds of data (not just geographical)

Libra is a highly usable Landsat imagery browser. It allows you to browse, sort, and download more than 275 Terabytes of open Landsat imagery as easily as booking an Uber. NGOs, journalists, and researchers use Libra to find recent imagery or to track changes over time.

Chapters of the National Atlas with topo and other data

A distributed archive of standardized geoscience information for the nation.

aggregated census data and GIS boundary files for Census administrative areas between 1790 and 2011

Basemaps for US census including some basic census data, and shapefiles for linking to census data.

A lot of the regional data analysis in Texas is conducted bythe local council of governments; so, much of the available datasets are available from the councils

The Texas Commission on Environmental Quality (TCEQ) is the environmental agency for the state. This site has Environmental data and records available from the TCEQ

This is a focal point for the production, interpretation, and distribution of demographic information for Texas. The Center produces and disseminates population estimates and projections for Texas, as well as other demographic information. Special emphasis is placed on data that may be useful to policy makers in dealing with issues regarding the demand for State services.

Besides historical maps, research, and data, the land office today uses GIS, GPS, and CAD systems to compile, analyze, and distribute the most accurate information possible about the location of natural and human-made resources. The website contains a collection of dynamic interactive mapping websites that give Texans access to the vast collection of spatial data available at the agency.

This site is Texas' primary source for Education statistics. It contains reports, statistics, queries, interactive tools, and downloadable data, with links on enrollment and success, course and facilities inventories, interactive institutional locator maps, and degrees offered. Many data tables are available by race/ethnicity and gender.

A reliable and unique state resource that provides high quality historic and current geospatial data products, education and training. It is a centralized clearinghouse and referral center for: 1.natural resource data; 2.census data; 3.data related to emergency management; and 4.other socioeconomic data.

A relatively new platform with data for the Houston area. The Kinder Institute Urban Data Platform (UDP) is a secure data repository and an analytical computing environment that provides research-ready urban data for the Houston Metropolitan Area. The UDP facilitates cross-disciplinary research and community studies to advance knowledge and information about Houston's people, government, and built environment. Some open source data is available, some will require registering for an account.
