Road detections from Microsoft- Maps aerial imagery

Published by: Open Development Cambodia

Bing Maps, a part of Microsoft's Bing suite of search engines, is releasing mined roads around the world. With detecting 47.8M km of all roads and 1165K km of roads missing from OSM, Its data is performed with Bing Maps imagery between 2020 and 2022 including Maxar and Airbus.

This dataset of road detections is derived from the project, adopted the Microsoft Open Source Code of Conduct. According to the website source through https://github.com/microsoft/RoadDetections, the source stated that "OSM Missing Data went through a final classifier to ensure that the precision is at least 95% (90% for USA now - to be updated to 95% in 2022). After classifier filters out potentially bad roads we remeasure the precision and make sure that it is 95% before releasing results. The data is freely available for download and use under the Open Data Commons Open Database License (ODbL). Lastly, the data with releasing around the globe is extracted only in Cambodia boundary.

Process Step	The dataset was derived from Southeastern Asia via https://github.com/microsoft/RoadDetections in zip format which using WGS84 coordinate system. The zip format consisting of Cambodia TSV format was reformatting through terminal line code of MacOSX: ""zipgrep -i "type" /path name/AsiaSouthEast-Full.zip \| cut -f2 > europe.geojson" to transform as geojson format. Next, the geojson is saved as Shapefile through QGIS software using WGS 84 / UTM zone 48N coordinate system.
