OSHDB: a framework for spatio-temporal analysis of OpenStreetMap history data
Earlier we published several blogposts introducing the ohsome platform and its parts (e.g. the ohsome API for example, which was often showcased here in the blog) and its backbone the OSHDB (very recently version 0.5 was published). A recent open access journal article gives even more background to the system, as shown below: Raifer, M,…

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…
