Exploring OSM history: the example of health related amenities
Introduction Exploring how OpenStreetMap data developed over time across different administrative untis might reveal interesting insights into the self organizing approach of the OSM communities and can potentially be used to derive intrinsic data quality indicators. It might even be possible to estimate the completeness of OSM for a specific key-value combination as done by…

How to become ohsome part 5: Measuring numbers of users editing different OSM features
Besides dealing with a snake, making quality assessments, or generating comparable statistics, one needs to know how to handle the whole functionality provided by the ohsome API to really become ohsome. And to achieve exactly that, this blog presents the last missing entry point to the API from the current toolkit, namely the /users resource. With its help you can receive aggregated…

Projekt “TARDUR” startet: Open-Source-Routenplanung mit zeitabhängigen Beschränkungen
Zeitabhängige Sperrungen und Nutzungsbeschränkungen von Straßen werden bislang in keiner frei verfügbaren Software zur Routenplanung genutzt. In dem im März gestarteten Projekt “TARDUR – Temporal Access Restrictions for Dynamic Ultra-Flexible Routing” gehen die Universität Heidelberg und die Firma GraphHopper dieses Problem an. Das Projekt wird im Rahmen der Förderrichtlinie Modernitätsfonds (“mFUND”) mit insgesamt 100.000 Euro…

meinGrün Umfrage: Wofür nutzen Sie städtische Grünflächen?
Alle Jahre wieder blühen die Kirschbäume vor unserem Institutsgebäude in voller Pracht und laden Passanten allen Alters ein zum Verweilen. Städtische Grünflächen wie diese leisten einen wichtigen Beitrag zur urbanen Lebensqualität, indem sie viele Funktionen wie Naturerfahrung, sozialen Austausch und Erholung ermöglichen. Jedoch eignet sich nicht jeden Grünfläche gleichermaßen für jeden Einzelnen und jede Aktivität.…

Project “TARDUR” starts: Open-source routing with time-dependent restrictions
Time-dependent restrictions and temporal road closures are so far not considered in any freely available software for route planning. Heidelberg University and the company GraphHopper aim to address this issue in their joint project “TARDUR – Temporal Access Restrictions for Dynamic Ultra-Flexible Routing”. The project started in March and is supported by the Federal Ministry…

OpenStreetMap History Database – version 0.5
The OpenStreetMap History Database (OSHDB) is what powers most of the functionality of HeiGIT’s ohsome platform. The ohsome API for example, which was often showcased here in the blog, is built on top of the OSHDB. Just recently, an open access software article about the OSHDB was published. Check it out to find out more…
