Recently videos with our contributions by HeiGIT to the FOSS4G conference were put online. Did you miss the event? Now you can watch whenever you like 🙂
Benni by HeiGIT explains who to use the ohsome.org framework to develop an OSM Confidence Index to support humanitarian mapping
FOSS4G 2021 Using the ohsome framework to develop an OSM Confidence Index to support humanitarian mapping
Together with Johnny Henshall from British Red Cross Benni also introduces the mobile crowdsourcing App MapSwipe – including the latest project types that we developed and added recently.
FOSS4G 2021 MapSwipe – an open-source mobile app putting communities on the map

OQT, the ohsome quality analyst relies on information from the OpenStreetMap (OSM) that has been processed using the ohsome OSM History Data Analytics Platform developed by HeiGIT. The aim of the ohsome framework is to make OpenStreetMap’s full-history data more easily accessible for various kinds of OSM data analytics tasks, such as data quality analysis, on a regional, country-wide, or global scale.
