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 plain [...]

Airborne light detection and ranging (LiDAR) data provides reliable information on forest structure. Related forest inventory approaches recently evolved into operational tools. Today, further optimization of existing approaches is pursued to ensure high data quality of the inventory information and cost-efficiency over varied environmental and silvicultural conditions. Synthetic LiDAR data has been suggested as useful [...]

Die Fachtagung Katastrophenvorsorge wird jedes Jahr vom Deutschen Roten Kreuz organisiert, mit dem Ziel eine Dialogplattform für verschiedene Akteuren der nationalen und internationalen Katastrophenvorsorge zu schaffen. In Kooperation mit dem Bundesamt für Bevölkerungsschutz und Katastrophenhilfe (BBK) und dem Zentrum für satellitengestützte Kriseninformation (ZKI), haben wir vom HeiGIT den Workshop „Geodaten in der Katastrophenvorsorge“ durchgeführt. Anhand konkreter [...]

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 [...]

This blog post is the start of a series of posts, which describe what you are able to do using the ohsome framework developed at the Heidelberg Institute of Geoinformation Technology (HeiGIT). OpenStreetMap (OSM), the biggest open map of our world, offers not only the current state of the data, but the whole historical evolution [...]

F-B Mocnik participates in the Complex Networks 2018 conference, presenting work about the impact of space on network representations.  Street networks have been examined in respect to their structure.  F-B Mocnik has previously examined networks from various domains, thereby demonstrating that the polynomial volume law applies to many of them.  The presentation at the conference [...]

Christmas is just around the corner and the disastermappers heidelberg are organizing another workshop on the use of OpenStreetMap data. As last year they will present different ways to craft personal Christmas gifts based on OpenStreetMap features. Additionally they will also show how to use open satellite imagery archives captured by Sentinel and Landsat mission. Together we [...]

We are happy to hereby share latest information about the 5th HOT Summit- the annual gathering of the Humanitarian OpenStreetMap Team community- which after great events in Washington, Brussels, Ottawa and Dar es Salaam, will next year come to the picturesque city of Heidelberg, September 19th and 20th. HOT Summit 2019 as well as the [...]

A mechanistic understanding of human activity patterns lays a foundation for many applications. The majority of the current research aims to outline human activity patterns mainly from spatiotemporal perspectives (i.e., modeling human mobility patterns), lacking of understanding of the motivations behind behaviors. The aim of a recently published study is to model and understand human [...]

Nowadays, several research projects show interest in employing volunteered geographic information (VGI) to improve their systems through using up-to-date and detailed data. The European project CAP4Access was one of the successful examples of such international-wide research projects that aimed to improve the accessibility of people with restricted mobility using crowdsourced data. In this project, OpenStreetMap [...]
