Step #1

Run cp env.sample .env and adapt the content of the .env file to your environment.

It must at least have the following environment variables:

DB_NAME='<db_name>'
DB_HOST='<host_name>'
DB_PORT=<port_number>
DB_USER='<user_name>'
DB_PASSWORD='<user_password>'
APP_HOST_PORT=<application_port_on_the_host>

Step #2

Create a config.yml file with the informations you want to display for each collection. You can take example on config.example.yml.

Step #3

Install the dependencies running the following command:

npm ci

Step #4

Start the server running the following command:

node index.js

Note: For development purposes, you can use nodemon to automatically restart the server when a file is changed. To do so, run the following command:

nodemon index.js

Step 5

If you want to have geopose information, add the entries is_azimuth (in case you have an azimuth instead of a yaw, the boolean must be true. In this case, we convert your azimuth to yaw), yaw_field, roll_field and pitch_field to your configuration file, as in the following example:

    providers:
      - type: feature
        name: PostgreSQL
        data:
          schema: public
          id_field: id
          table: images
          geom_field: location
          is_azimuth: true
          yaw_field: azimuth
          roll_field: roll
          pitch_field: tilt
