Abstract: 

The GeoConnections Discovery Portal provides an infrastructure through which one can search and access geospatial data from many organizations.  The directory contains over 9000 databases from over 600 organizations.  These databases can be searched by data format , geographic extent, and type of geography.  Not all data sources in the directory can be accessed for free, but the queries can be filtered such that only free sources are shown.  Please be aware that some free resources, such as GeoBase, require you to make an account before you can access data.  Although this directory contains data at a global extent, it is a Canada-centric website, and therefore many databases will portray Canadian information.

The following topics and sub-topics are available filters for the geospatial data search:

Atmosphere/Weather: Current weather and forecasts, General climate data, Weather disasters, Winds

Geology: Earthquakes

Land Surface: Agriculture, Forestry, Land use, Snow, Soil, Topography, Vegetation

Water: Freshwater, Hydrogeology, Lake ice, Oceans, Sea ice

 

Metadata: 

In the search results, each item will have a link on the right that says "full metadata", which will take you to a separate metadata webpage.  The search result will also show a checkmark icon next to some items, meaning that the metadata for that item has been verified. Most datasets are for sale - look for an icon indicating those which can be obtained free.
