February 2020 - 77 articles

Cover Story: Over the past decade, the adoption of open source software and open data principles has accelerated worldwide, with geospatial domain often leading the way. This paper reviews the current state of the Open Source Geospatial Foundation (OSGeo) software ecosystem and its communities, while also highlighting major trends outside OSGeo. Collaboratively contributed, authoritative, and scientific open geospatial data are discussed, along with new developments in open data standards. The openness has changed how geospatial data is collected, processed, analyzed, and visualized. For example, generalized 3D vegetation fragmentation index derived from open lidar point cloud data was computed and visualized using open source GRASS GIS software (see reference [15] in the article).View this paper.
