Near realtime OpenStreetMap data and stats: OSHDB and ohsome API are now updated hourly
We have exciting ohsome news! As many of you know, past OSHDB updates happened weekly and led to a delay between the data in OpenStreetMap (OSM) and our database. Basically, you had to wait up to a week to see changes in OSM reflected in the OSHDB. From this point forward, that lag is a…

Human-in-the-loop development of spatially adaptive ground point filtering pipelines — An archaeological case study
LiDAR data have become indispensable for research in archaeology and a variety of other topographic applications. To derive products (e.g. digital terrain or feature models, individual trees, buildings), the 3D LiDAR points representing the desired objects of interest within the acquired and georeferenced point cloud need to be identified. This process is known as classification,…

How to become ohsome part 13 – An ohsome way to check if OSM is up to date
At long last, welcome to another addition of our How to become ohsome-series! This one is special because we’re discussing a third-party application that uses ohsome API as back-end to accumulate historical OSM data. Although this innovation isn’t directly about our API, it’s close enough (and exciting enough) to merit inclusion and just one more opportunity for…
