Open Urban Mapping

Introduction

This project was mainly aimed at demonstrating "AI-Mapping" leveraging AI technologies to analyse and digitize aerial and satellite imageru. As soon as there are more tools and more open data available we reviewed the concept to share specific datasets with the community. It is dedicated to analysis of urban environment and land resources as well as to the wide range of educational and resesrch projects.

Mapping contribution

If you are an OpenStreetMap contributor, you can use this data to contribute to OSM directly or accelerate your own mapping efforts. Since the data was generated automatically, it should be thoroughly validated before import. You can preview and edit the data using QGIS, the OSM ID editor ("custom Map Data"), or JOSM. We also strongly recommend that you check OSM imports community guidelines. We've created the Open Urban Mapping wiki - you can find some tips on editing and doing imports based on our datasets.

The auto-mapping approach can also be used to help create maps from scratch in times of emergencies such as in Irkutsk region, Russia, that was heavily flooded in the summer 2019, so we appreciate any contribution and/or related data requests.

If you'd like to help us with documentation, integration of datasets into third-party applications like JOSM, RapID, etc., or promote this project, please check out the issues or create one to submit your request. You can also contact us directly at hello@geoalert.io
