Preview: Spatial Joins using the OpenStreetMap History Database OSHDB
Max is two and loves spending Monday afternoons with his Dad at the playground. Finding a suitable playground however isn’t easy, since a few criteria must be met: there should be a bench and some trees nearby to get shelter from the sun and an ice cream shop within the neighbourhood. Using the new spatial…

Neues mFUND Project: Temporal Access Restrictions for Dynamic Ultra-Flexible Routing – TARDUR
Problemstellung Bis dato wird eine wichtige Eigenschaft infrastruktureller Straßennetzdaten wie OSM in noch keiner frei verfügbaren Routing Anwendung voll ausgenutzt: zeitliche Restriktionen auf Straßen und Wegen, wie etwa tageszeit- oder saisonale Fahrbahnbeschränkungen. Dies ist unter anderem für Transport-Logistik-Firmen für ein effizientes Flottenmanagement (z.B. zeitlich variable Fahrverbote für Lastkraftwagen) von Bedeutung, aber auch im Hinblick auf eine…

Using Openrouteservice in the data science platform alteryx
You can also use Openrouteservice via the self-service data analytics plattform alteryx, when you are a user of that data science product. Pablo Sáenz de Tejada (The Information Lab) has shared some macros on the alteryx public gallery using the Openrouteservice API that allows you to geocode addresses, calculate routes and create isochrones using the alteryx…

OpenStreetMap history explorer – ohsomeHeX published
The exploration of the history of OpenStreetMap data presents an important step to uncover semantic connections, regions of interest and their contiguity in time and space at varying scales. Therefore, the HeiGIT Big Spatial Data Analytics team presents a first beta version of the new OpenStreetMap History eXplorer (ohsomeHeX). It resembles the idea of the OSMatrix¹,…

Solve routing optimization with VROOM + openrouteservice
In a Vehicle Routing Problem (VRP, an example is the Traveling Salesman Problem), we are concerned with finding optimal routes for a fleet of vehicles having to reach given destinations, e.g., in order to deliver goods to customers. Due to its high computational complexity, this task requires dedicated VRP solvers, such as VROOM. In collaboration with…
