To run analysis:
git clone https://github.com/morganherlocker/nepal-damage-analysis cd nepal-damage-analysis npm install node conflate/index.js
This will create roads.geojson and buildings.geojson files in ./data. These large geojson files can be sent through tippecanoe for creating vector tile datasets.
cd data cat buildings.geojson | tippecanoe -o buildings.mbtiles cat roads.geojson | tippecanoe -o roads.mbtiles
Processing the entire impact area will take several hours on a typical laptop, so a large multicore ec2 is recommended.
