tree-lib

This library provides tree recommendations for different climate change scenarios.

Data

Data for tree type projections is provided as a CSV file and needs to be converted into JSON to be usable by the library.

1. Install NodeJS 10, Yarn and Docker Compose.
2. Install dependencies: yarn install
3. Make sure Docker can overwrite JSON files (ie. on Linux chmod 777 data/*.json)
4. Run transformation: yarn run data:transform

NaiS

NaiS data is provided as CSV files and imported into the PostgreSQL database for further processing. New data needs to be converted to UTF-8 encoding with the following command: iconv -f ISO-8859-1 -t UTF-8 [source].csv > [target].csv

Vector Tiles

Spatial data is downloaded from different sources and imported into the database. To add or update spatial data have a look into data/spatial. For the app we generate one vector tileset using the following commands:

1. Start database: yarn run data:start
2. Export spatial data to GeoJSON files (might take a long time): yarn run data:spatial:export
3. Transform GeoJSON files to single vector tileset: yarn run data:spatial:tile
4. Generate font glyphs for Mapbox GL (currently only NodeJS 10): yarn run data:spatial:fonts
5. Deploy tiles to a webserver or to Netlify (currently maintained by geOps): yarn run data:spatial:deploy
