Developed Object detection framework using Pytorch and fastai, and trained it to detect dirt work, drill pits, and Frac Ponds in Sentinel 2 satellite imagery. The resulting frozen inference graph is then fed into Detect Objects using Deeplearning geoprocessing tool in ArcGIS Pro to then generate shapefiles for all detected features in any given extent.
