Tile Imagery:

neo tile --zoom 19 --bands 1,2,3 --nodata_threshold 25 --rasters train/*/*[^-]/*tif --out train/images

Retrieve and tile labels accordingly:

neo cover --dir train/images --out train/cover.csv
neo rasterize --geojson train/*/*-labels/*.geojson --type Building --cover train/cover.csv --out train/labels

Launch training :

neo train --dataset train --epochs 5 --out model
neo eval --checkpoint model/checkpoint-00005.pth --dataset train

Retrieve, prepare and predict on a new imagery:

neo tile --zoom 19 --bands 1,2,3 --nodata_threshold 25 --rasters predict/*/*[^-]/*tif --out predict/images
neo predict --checkpoint model/checkpoint-00005.pth --dataset predict --metatiles --out predict/masks

Compare our trained model prediction against labels:

neo cover --dir predict/masks --out predict/cover.csv
neo rasterize --geojson predict/*/*-labels/*.geojson --type Building --cover predict/cover.csv --out predict/labels
neo compare --mode stack --images predict/images predict/labels predict/masks --cover predict/cover.csv --out predict/compare
neo compare --mode list --labels predict/labels --masks predict/masks --max Building QoD 0.80 --cover predict/cover.csv --geojson --out predict/compare/tiles.json

neo compare --mode side --images predict/images predict/compare --cover predict/cover.csv --out predict/compare_side

Vectorize results:

neo vectorize --masks predict/masks --type Building --out predict/building.json
