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”…
