climatemaps

An interactive web application for visualizing global historical climate data and future climate projections. It show temperature, precipitation, and other climate variables with support for multiple climate scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5) and time periods (2020-2100).

Development

Dependencies

GDAL

GDAL is needed for the gdal2tiles.py script that creates map-tiles from a single image (matplotlib plot).

Install GDAL with conda to prevent the need to install a hugh number of system level dependencies:

conda install -c conda-forge gdal==3.11.0

Tippecanoe

WARNING: tippecanoe 1.19.1 is the latest version that produces valid GeoJSON due to issue mapbox/tippecanoe#652

TODO: migrate to active fork https://github.com/felt/tippecanoe

sudo apt install libsqlite3-dev
git clone https://github.com/mapbox/tippecanoe.git
cd tippecanoe
git checkout tags/1.19.1
make -j
make install

tileserver-gl

npm install -g tileserver-gl

Run

Create contour data

Run:

python scrips/create_contour.py

to create contour and raster mbtiles.

Create tileserver config

python scripts/create_tileserver_config.py

to generate the tileserver config.

Run the backend (FastAPI server)

uvicorn api.main:app --reload

Run the tileserver (tileserver-gl)

tileserver-gl --config tileserver_config_dev.json --port 8080

Run the client (Angular)

In ./client run:

ng serve

Or run against the openclimatemap.org API and tileserver:

ng serve --configuration=production-backend

Tests

Run:

pytest

Build and deploy (to openclimatemap.org)

Everything

Build and deploy client and backend:

bash scripts/deploy.sh

TODO: include create tiles, create config and upload tiles

Client

Deploy the client angular app:

bash scripts/deploy_client.sh

API and TileServer

bash scripts/deploy_backend.sh

Upload tiles (optional)

If you have locally created tiles, upload them to the server with:

rsync -avP data/tiles openclimatemap.org:/home/bart/climatemaps/data/
