I counted all of the yurts in Mongolia using machine learning (via) Fascinating, detailed account by Monroe Clinton of a geospatial machine learning project. Monroe wanted to count visible yurts in Mongolia using Google Maps satellite view. The resulting project incorporates mercantile for tile calculations, Label Studio for help label the first 10,000 examples, a model trained on top of YOLO11 and a bunch of clever custom Python code to co-ordinate a brute force search across 120 CPU workers running the model.
