ENVS 250: Geographic Information Systems

Oregon's authoritative geospatial repository. GEOHub is designed to be a one-stop hub for geospatial data and resources for the public and public bodies for research, business and public services. It is built to organize authoritative data by Framework themes and provide users a searchable catalog to locate and access data.

Oregon's Open Data Program is a new program with executive leadership from the Chief Data Officer, and supports agencies in inventorying, prioritizing, and publishing data assets as open data.

The map and data products are searchable through the Download Application (Training Video Lessons 4a-d). Also, LidarExplorer can be used for advanced searching and visualization for lidar and digital elevation models (DEMs) data. Historical maps can also be explored in detail and downloaded via the TopoView Application (Training Video Lesson 9b and 9c). The National Map Datasets are available to download at: https://apps.nationalmap.gov/datasets/

The National Map (TNM) is a collaborative effort among the USGS and governmental, academic, non-profit, and industry partners to improve and deliver topographic information for the Nation.

Climate Data Online (CDO) provides free access to NCDC's archive of global historical weather and climate data in addition to station history information. These data include quality controlled daily, monthly, seasonal, and yearly measurements of temperature, precipitation, wind, and degree days as well as radar data and 30-year climate norms.

Browse databases, surveys, reports and other statistical products created by BTS. Use BTS tools and apps to build your own statistical tables, graphics and maps. BTS is one of more than a dozen principal federal statistical agencies. It's focus is on transportation within the U.S. as well as transportation to and from the U.S.

Access LANDSAT, IRS, and other imagery that spans the globe, as well as DEMs, LIDAR, Land Use and Land Cover, and topographic maps.

Free vector and raster map data at 1:10m, 1:50m, and 1:110m scales. Designed for creating high-quality maps.

All features that appear in this crowdsourced map can be downloaded in bulk from Geofabrik. For more targeted extracts, add the QuickOSM plugin for QGIS, or download and add the OSMquery toolbox for ArcGIS.

The federal government's central data repository. You can narrow the results down to geospatial layers.

These files are generalizations of the TIGER files that are appropriate for mapping at different scales. Coastal water has been removed from the feature boundaries, and edges have been simplified to varying degrees (see examples above).

Generate daily, monthly, or 30-year normal rasters for temperature (min, max, mean), precipitation, dew point, and a few other measures.

Detailed administrative, legal, and statistical boundaries as well as the features used for delineating them (water bodies, roads, landmarks). Features represent precise boundaries.

Several different apps for accessing elevation, contour, LIDAR, land use / land coverage, and topographic map layers.

ESRI's catalog of data. Can also be accessed from within ArcGIS Pro (Map Ribbon - Layer Panel - Add Data - Living Atlas) and ArcGIS Online.

A directory of websites that provide free GIS data from around the world. Maintained by the GIS Librarian at Cornell University.

A large collection of links to free GIS data.

A community of universities provide access to many of their datasets through this shared spatial-search interface.
