Next generation services https://api3.geo.admin.ch for https://map.geo.admin.ch In mid August 2022 the project has been migrated to python3, docker and eu-central-1.

The required environment variables are set in .env.default. They can be adapted or you can use a copy of .env.default, e.g. .env.mine and use that instead.

Install the python virtual environment (still virtualenvat this point)

make setup

Build the Pylons settings files and run the local waitress server

summon make serve

You may want to customize the variables. Copy the file .env.default as .ven.mine, change the variables you want and use them with

summon make ENV_FILE=.env.mine serve

📖 You need some external ressource to run the service, see External ressources dependencies

To run the service locally you need to have access to the following external ressources:

• Postgresql database pg-geodata-replica.bgdi.ch
• S3 bucket service-mf-chsdi3-grid-geojsons-dev-swisstopo (NOTE: this bucket is only required by some of the Identity endpoints)

You can use the ssh port forwarding feature to have access to pg-geodata-replica.bgdi.ch by using the jump host:

ssh ssh0a.prod.bgdi.ch -L 5432:pg-geodata-replica.bgdi.ch:5432

Then set the DBHOST environment variable to localhost (you can do this in your own environment file e.g. .env.mine and run the make file as follow: summon make ENV_FILE=.env.mine serve)

To have access to the S3 bucket, you can either set your AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variable. ⚠️ When using those variables make sure that the command are not saved into history file !

Alternatively if you are using zsh you can use the aws plugin (see oh-my-zsh aws plugin) with the following command:

acp swisstopo-bgdi-dev

This command will automatically use your AWS profile swisstopo-bgdi-dev for any AWS connection services.

make dockerbuild

summon make dockerrun

📖 You need some external ressource to run the service, see External ressources dependencies

First log in to the AWS ECR registry with:

make dockerlogin

afterwards you can push the locally built image to ECR with:

make dockerpush

• PostgreSQL DB pg-geodata-replica.bgdi.ch must be reachable
• Access to AWS services
  • Read access to S3 bucket service-mf-chsdi3-grid-geojsons-dev-swisstopo (can be disable with S3_TESTS=0)

See External Ressources Dependencies for more infos on those prerequisites.

To run the tests enter

summon make test

Or if you use your own environment file

summon make ENV_FILE=.env.mine test

⚠️ If you don't have AWS Access you can disable the S3 tests as follow

summon make S3_TESTS=0 test

In order to download all images of a layer in the correct format and with the correct dimensions, simply use:

make legends BODID=ch.layername WMSHOST=wms.geo.admi.ch

Alternatively, you can also download a WMS legend for a specific scale.

make legends BODID=ch.layername WMSHOST=wms.geo.admi.ch WMSSCALELEGEND=1000

You will need the optipgn tool order to download the legends, use sudo apt install optipng to install it.

We are currently using the FLAKES 8 convention for Python code. You can find more information about our code styling here:
