GeoDeep's AI Detection on Maxar's Satellite Imagery

Summary

GeoDeep is a Python package that can detect objects in satellite imagery. It's made up of 1,026 lines of Python and uses ONNX Runtime and Rasterio extensively. GeoDeep was written by Piero Toffanin, who is based in Florida and is the co-founder of OpenDroneMap. He also wrote LibreTranslate which I covered in a post a while back. Maxar is a satellite manufacturer and constellation operator. They run an open data programme and they often releases imagery from areas before and after natural disasters strike. Below are the locations of their releases to date. On March 28th, an earthquake struck Myanmar and it reached as far away as Bangkok, Thailand. Spyridon Staridas, a cartographer based in Greece, put together this map of earthquake history around the world. Thailand is surrounded by countries that are earthquake-prone but these are relatively rare in Thailand compared to elsewhere in Asia. Shortly after the earthquake, Maxar released historical satellite imagery from the affected areas and later included imagery taken after the earthquake. As of this writing, they've released almost 10 GB of GeoTIFFs. Below are the imagery footprints in central Myanmar. The imagery spans from February 2nd till early April. Below are the satellite footprints for Bangkok. In this post, I'll run some of GeoDeep's built-in AI models on Maxar's satellite imagery of Myanmar and Bangkok, Thailand. My Workstation I'm using a 5.7 GHz AMD Ryzen 9 9950X CPU. It has 16 cores and 32 threads and 1.2 MB of L1, 16 MB of L2 and 64 MB of L3 cache. It has a liquid cooler attached and is housed in a spacious, full-sized Cooler Master HAF 700 computer case. The system has 96 GB of DDR5 RAM clocked at 4,800 MT/s and a 5th-generation, Crucial T700 4 TB NVMe M.2 SSD which can read at speeds up to 12,400 MB/s. There is a heatsink on the SSD to help keep its temperature down. This is my system's C drive. The system is powered by a 1,200-watt, fully modular Corsair Power Supply and is sat on an ASRock X870E N...
