Find here a new update of the OSMlanduse.org map. By injecting known tags provided by OpenStreetMap (OSM) into a remote sensing feature space using deep learning, tags were predicted when absent thus creating a contiguous map - initially for the member states of the EU. By design our method can be applied when- and wherever [...]

As part of the LOKI project (Luftgestützte Observation Kritischer Infrastrukturen), a first test run of a newly launched OpenStreetMap (OSM) completeness mapping project in MapSwipe has been conducted yesterday.
The aim of the LOKI project is to develop an interdisciplinary system that enables fast and reliable airborne situation assessments following an earthquake. The system [...]

Recently we’ve had the first minor release 1.1 of the ohsome API, which brings several new features and upgrades. In the following lines we want to present to you the most important ones.
Prior to 1.1, when you were requesting data through one of our data extraction endpoints, you would always get the geometries clipped to [...]

The open, flexible and collaborative nature as well as the benefits and advantages of OpenStreetMap (OSM) lead to the creation of a whole new ecosystem evolving around the project. They range from local and global communities of data and software developers to a large amount of tools and services like disaster [...]

A recently published paper provides a bibliometric review between integration of authoritative and volunteered geographic information (VGI) for the specific purpose of cartographic updating of urban mappings. The adopted methodology was through a bibliometric survey of the literature published by Web of Science and Science Direct. The period was evaluated from 2005 to 2020 and [...]

The 3rd edition of the international summer school “Close-range Sensing Techniques in Alpine terrain” took place in Obergurgl, Austria, in June 2019. A group of 40 young researchers (mainly PhD students) participated to learn about various sensors, processing techniques, and analysis methods for different topics in high-mountain research.
A recently published article [...]

Semantically rich maps are the foundation of indoor location‐based services. Many map providers such as OpenStreetMap and automatic mapping solutions focus on the representation and detection of geometric information (e.g., shape of room) and a few semantics (e.g., stairs and furniture) but often still neglect room usage. To mitigate the issue, a new published paper [...]

#OpenStreetMap is turning 16! Happy Birthday from the HeiGIT team.
16 years of OSM activity has created the most feature rich and global free multi purpose map that the world has ever seen.
The ohsome team at HeiGIT has created several tools and technologies to have a closer look into that history of OSM edits (OSHDB, Ohsome [...]
