A Top 10 List of Useful Geospatial Data Portals | Spatial Reserves

We have been writing this geospatial data column since 2012, when our book The GIS Guide to Public Domain Data, was published. Over the 5 years that have elapsed, in addition to keeping issues such as data quality, copyright, privacy, and fee vs. free at the forefront of the conversation, we have tested and reviewed many geospatial data portals. Some of these portals promise more than they deliver, some have been frustrating, but some have been extremely valuable in GIS work. We have decided to list 10 of those that we have found most useful, rich with content, easy to use, and with metadata that is available and understandable. In considering such a list, we realize that “most useful” really depends on the application that one is using GIS for, but the following sites should be useful for users in many disciplines. Some allow for data to be streamed from web servers into your GIS software, and all allow data to be downloaded.
