Four key trends have influenced the evolution of open land data since the publication of the original edition of the State of Open Data. The first is the growing number of stakeholders and initiatives that focus on land data as a priority. This development is evidenced by how many community organisations, as well as indigenous organisations, increasingly mobilise around land data issues and stake their claims as data custodians.The second trend involves the ongoing developments to measure and benchmark land data, as well as to develop tools to uncover and open up land data at national and global levels for increased transparency. A third trend has seen the emphasis shifting away from the opening up of data for its own sake to understanding how the use, access, and sharing of data can create value and deliver services that promote equity and justice while protecting privacy, land, and human rights. There is increasing evidence on the use and impact of open land data on social and economic development. The fourth and final trend is that open data standards and infrastructures have continued to be developed and improved specifically for the land data sector.
