New paper on “improving change analysis with full temporal information”
In recently published work, we show how change analysis from near-continuous 3D time series improves by considering full temporal information. How can it be done? Using 4D objects-by-change! The method was applied to an hourly time series of terrestrial laser scans acquired for snow cover monitoring. In the snow-covered scene at the Zugspitze ski resort,…

Where to map in OpenStreetMap next? Experiences from Mozambique, India, and Tonga
OpenStreetMap (OSM) has been intensively used to support humanitarian aid activities, especially in the Global South. Its data availability in the Global South has been greatly improved via recent humanitarian mapping campaigns and due to the efforts of local communities. However, large rural areas are still incompletely mapped. The timely provision of map data is…

Join our final “SocialMedia2Traffic” project presentation on March 22
Navigation services need time dependent information on traffic speed to generate suitable routes and yield accurate travel time estimations. However, this information is not available free of cost globally. Within the recently completed project “SocialMedia2Traffic”, we have developed a system to model traffic speed of urban roads depending on the time of day based on…
