Analyzing Bikeability
For various reasons biking is becoming a more frequently used mode of transportation. It offers flexibility, is quite cheap compared to other modes of transportation, helps with fitness and is almost carbon neutral. To evaluate how well adapted the existing infrastructure is to accommodate biking, Manuel Kraft of HeiGIT created the “Bikeability-Index”. Analyzing Bikeability There…

Version 1.0 of the ohsome quality API and ohsome dashboard
At HeiGIT and in particular within the ohsome team, we strive to provide valuable insights into OpenStreetMap (OSM) data. The ohsome API offers aggregated statistics on the evolution of OSM elements since 2020. These are made easily accessible by the ohsome dashboard. With the ohsome quality API, previously called ohsome quality analyst (OQT), we continue…

Bachelor’s thesis: Using OSM for location analyses of residential real estate projects – an extrinsic analysis of data quality
In his bachelor’s thesis, supervised by HeiGIT’s apl. Prof. Dr. Sven Lautenbach, Lars Reckhaus examined the suitability of OpenStreetMap (OSM) for location analyses in the context of residential real estate projects. Typically, such analyses require the use of a variety of data sources and are mostly performed manually. For this reason, they tend to be…
