New paper on OSM feature completeness modelling accepted for AGIT symposium
The availability of data on public transport is a prerequisite for numerous spatial data applications such as routing, accessibility analyses or route planning. OpenStreetMap (OSM) – as a global platform for Volunteered Geographic Information – is one of the options for sharing public transport data. The data completeness on OSM, however, is characterized by heterogeneity. Results…

OSM data quality analysis for different stages of the mapping process
Slums are an important operational area for humanitarian organisations: Because of provisional housing, poor sanitation and difficult socio-political circumstances offers of help from such organisations are important and often necessary. For such deployments, humanitarian actors rely heavily on Volunteered Geographic Information (VGI), as official maps and data are often incomplete. This makes it all the…
