The GIS Guide to Public Domain Data explains sources and quality of spatial data
This week sees the publication of The GIS Guide to Public Domain Data. Available in both hard copy and as an e-book, the guide provides GIS users with detailed information about the sources and quality of spatial data available in the public domain and the policies that govern its use.
When co-author Joseph Kerski and I started this project, the open data revolution was well under way. Many individuals and organisations were advocating for improved access, preferably at no cost, to the vast reserves of spatial data collected by governments and organisations at local, regional, national, and international levels. At the same time, recent technological innovations, such as crowd sourcing and cloud computing, were also having a major impact on how people access, collect and work with spatial data.
Together these technical and organisational changes have had, and will continue to have, a significant influence on the availability of data in the public domain.
