Create dot .env file inside root directory. Make sure to add the following content repaced by your actual values
DB_PASS=postgres
DB_HOST=localhost
DB_USER=postgres
DB_NAME=postgres
DB_PORT=5432
git pull

Run sql statements inside open-trees-map root directory
sudo -i -Hu postgres psql -U postgres -h localhost -d postgres -p 5432 < data/baumkataster_schema.sql
Notice, this must only be done when felling of trees dataset added
Note, calling
transform_epsg.pyhas three parameters, first is the source second the source projection EPSG number and last the destination EPSG number. Make sure to verify that your EPSG number are the correct one.

Notice, this must only be done when felling of trees dataset has been updated
Note, calling
merge_fellings.pyhas two parameters, first one is the path the fellings file, most likely a csv file. The second one is the path of the inventory file most likely a geojson file. Make sure to verify that both files are valid and test results.
