Routing optimization in a humanitarian context
Routing optimization generally solves the Vehicle Routing Problem (a simple example being the more widely known Traveling Salesman Problem). A more complex example would be the distribution of goods by a fleet of multiple vehicles to dozens of locations, where each vehicle has certain time windows in which it can operate and [...]

Farm Shops are ohsome
Posted in Services on Jul 5th, 2019
Welcome back to another ohsome blog post. Today, we will present the results of a recent analysis performed by our student assistant Jascha, who took a look at the distribution and development of farm shops (in German: Hofläden) at different scales in OpenStreetMap (OSM). This analysis is based on previous work within the global climate protection [...]
IT IS HOT! So you are looking for a more shady pedestrian route through the urban jungle? You might then prefer some routes that go through public green spaces with trees and bushes. Thank goodness we are working already on such green and also shady routing together with some partners in the mFund project meinGrün. [...]
Today, June 5 is the #WorldEnvironmentDay. World Environment Day is the United Nations day for encouraging worldwide awareness and action to protect our #environment. Above all, World Environment Day is the “people’s day” for doing something to take care of the Earth. That “something” can be local, national or global. This is a good opportunity to [...]

The progress of the implementation of the targets set by the Sendai Framework for Disaster Risk Reduction (DRR) have been key discussion points during this years Global Platform in Geneva. [...]
OpenRouteService with waypoint optimization
Posted in Services on May 22nd, 2019
As promised earlier this year, we are very happy to finally announce the unveiling of our new route optimization endpoint!
We deployed an instance of the popular Vroom open-source engine, which is capable of solving complex Vehicle Routing Problems (VRP) in record time. This type of problem always occurs when multiple locations need to be visited in [...]
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 [...]
MapSwipe for Change Detection Analysis

The Humanitarian OpenStreetMap Team (HOT) , the Heidelberg Institute of Geoinformation Technology (HeiGIT) , and the wider MapSwipe Community started working on an MapSwipe extension to monitor changes in satellite imagery. The goal of the two-month project is to extend the app with new functionalities that would allow the users to compare two satellite images [...]
OSHDB: a framework for spatio-temporal analysis of OpenStreetMap history data
Posted in Publications, Services, Software on Apr 24th, 2019
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:

Projekt “TARDUR” startet: Open-Source-Routenplanung mit zeitabhängigen Beschränkungen
Posted in OSM, Press release, Research, Services, Software, Traffic on Apr 23rd, 2019
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 [...]
