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…

Erreichbarkeitsanalyse von Haltestellen des öffentlichen Personennahverkehrs in Stuttgart per Openrouteservice
In einer aktuellen Publikation der Stadt Stuttgart wird die Erreichbarkeit von Haltestellen des öffentlichen Personennahverkehrs in Stuttgart untersucht. Für die Berechnung der Isochronen wurde das kostenfrei nutzbare QGIS-Plugin OSM Tools verwendet. Dieses nutzt den seit 2008 verfügbaren Openrouteservice des Heidelberg Institute for Geoinformation Technology (HeiGIT). Das Toolset umfasst Routing, Geocoding, Isochronen und Matrixberechnungen, entweder interaktiv im…

The potential of OSM for landuse, health and humanitarian applications
Recently, Michael Schulz from GIScience Heidelberg gave a talk at the colloquium of Prof. Carl Baierkuhnlein at the University of Bayreuth. During his talk he presented the results on OpenStreetMap usage targeting humanitarian applications, healthy and green routing based on openrouteservice and ecological analysis or the global climate protection map. OSM is harnessed for an abundance…

openrouteservice-js – your JS library for spatial node applications!
And here comes another little Christmas present by HeiGIT: In addition to our previously released and highly appreciated python and R libraries we now offer an additional JavaScript API making the usage of the openrouteservice ecosystem covering the entire globe based on OpenStreetMap in your web applications terribly simple. From now on you will be…

openelevationservice: enrich geometries with elevation
We published a new endpoint within the openrouteservice API ecosystem: openelevationservice. It queries a remote DEM for every vertex of a LineString or Point geometry. The underlying DEM is limited to SRTM v4.1 by CGIAR Consortium for Spatial Information as of now, though we’re working towards integrating more high-resolution datasets. openelevationservice returns the altitude of…

Spatial conceptual compliance analysis with the OpenStreetMap History Database (OSHDB)
In a previous blog post we performed a conceptual compliance analysis between OSM data and several tagging-guidelines using the OSHDB API. The results were visualized in a line chart, comparing the different compliance ratio over several months. The following analysis focuses on a spatial representation of the conceptual compliance. It is conducted for the “iD-editor”…
