dhr-visualizer

Visualizations of satellite data

Deploy

Deployment is done using Docker.

Visualization is dependent on gjtiff that can be found here. It must be cloned into dhr-visualizer root directory:

git clone https://github.com/MartinPulec/gjtiff.git

Also variables_secret.env must be created in dhr-visualizer root directory as follows:

DHR__CONNECTOR_HOST_BASE="https://dhr1.cesnet.cz/"
DHR__CONNECTOR_USERNAME=""
DHR__CONNECTOR_PASSWORD=""

CDSE__CONNECTOR_S3_HOST_BASE="https://eodata.dataspace.copernicus.eu/"
CDSE__CONNECTOR_S3_HOST_BUCKET="eodata"
CDSE__CONNECTOR_S3_REGION_NAME="default"
CDSE__CONNECTOR_S3_ACCESS_KEY=""
CDSE__CONNECTOR_S3_SECRET_KEY=""

Final tree will then look like this:

.
├── backend
├── frontend
├── gjtiff
├── docker-compose.yml
├── variables.env
└── variables_secret.env

Then the deployment is matter of running:

docker compose up

Frontend will be accessible at 0.0.0.0:8080, backend at 0.0.0.0:8081. These ports can be changed in docker-compose.yml at each service respectively.

Configuration

By default application uses local datahub relay specified in variables.env:

DHR__USE_DHR="True"
DHR__CATALOG_ROOT="https://stac.cesnet.cz/"

and variables_secret.env:

DHR__CONNECTOR_HOST_BASE="https://dhr1.cesnet.cz/"
DHR__CONNECTOR_USERNAME=""
DHR__CONNECTOR_PASSWORD=""

If you do not want to use it, set variable DHR__USE_DHR to False:

DHR__USE_DHR="False"
