The Tasks of the Crowd: A Typology of Tasks in Geographic Information Crowdsourcing and a Case Study in Humanitarian Mapping
In the past few years, volunteers have produced geographic information of different kinds, using a variety of different crowdsourcing platforms, within a broad range of contexts. However, there is still a lack of clarity about the specific types of tasks that volunteers can perform for deriving geographic information from remotely sensed imagery, and how the…

Exploring the Missing Maps Project – Tasking Manager statistics
The HOT Tasking Manager is the tool where most of the work of the Missing Maps community and members happens. The projects created tell us a lot about the current mapping efforts and also show where we already succesfully mapped basic infrastructures like roads and human settlements. Tools like OSMatrix or OSM Analytics try to…

Beyond 3-D: The New Spectrum of LiDAR Applications for Earth and Ecological Sciences
Capturing and quantifying the world in three dimensions (x,y,z) using light detection and ranging (lidar) technology drives fundamental advances in the Earth and Ecological Sciences (EES). However, additional lidar dimensions offer the possibility to transcend basic 3-D mapping capabilities, including i) the physical time (t) dimension from repeat lidar acquisition and ii) laser return intensity…
