Visualization of the satellite data
Deployment is done using Docker.
Visualization is dependent on gjtiff processing software that can be found here. It must be cloned into dhr-visualizer root directory:
git clone https://github.com/MartinPulec/gjtiff.gitAlso .env must be created in dhr-visualizer root directory as follows:
FRONTEND_DOMAIN="preferred.domain.cz"
FRONTEND_EMAIL="[email protected]"
APP_NAME="Oculus"
APP_LOG_LEVEL="DEBUG"
UVICORN_SERVER_HOST="0.0.0.0"
UVICORN_SERVER_PORT=8081
UVICORN_SERVER_PREFIX="/api"
DHR_USE_DHR="True"
DHR_CATALOG_ROOT="https://stac.domain.cz/"
DHR_CONNECTOR_HOST_BASE="https://dhr.domain.cz/"
DHR_CONNECTOR_USERNAME="USERNAME"
DHR_CONNECTOR_PASSWORD="PASSWORD"
# DHR (DHuS) is being deprecated in favor of GSS. See: https://docs.metacentrum.cz/en/docs/related/collgs
CDSE_CATALOG_ROOT="https://catalogue.dataspace.copernicus.eu/odata/v1/"
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="ACCESS_KEY"
CDSE_CONNECTOR_S3_SECRET_KEY="SECRET_KEY"
# Guide to obtain CDSE S3 credentials can be found here: https://documentation.dataspace.copernicus.eu/APIs/S3.html
DOCKER_SHARED_DATA_DIRECTORY="/data"
MONGO_USER="oculus"
MONGO_PASSWORD="MONGO_PASSWORD" # Any can be chosen for the initial run.
MONGO_DB="oculus"
MONGO_URI="mongodb://${MONGO_USER}:${MONGO_PASSWORD}@oculus_mongodb:27017/${MONGO_DB}?authSource=admin"
CELERY_BROKER_URL="redis://redis:6379/0"
CELERY_RESULT_BACKEND="redis://redis:6379/0"Final tree will then look like this:
.
├── backend
├── frontend
├── gjtiff
├── docker-compose.yml
├── .env
Then the deployment is matter of running:
docker compose up -dFrontend will be accessible at ${FRONTEND_DOMAIN} backend at ${FRONTEND_DOMAIN}/api.
- Docker
- CUDA capable GPU (tested with NVIDIA GeForce RTX 4080)
- Access to CDSE S3 storage
Currently Oculus supports two data sources - CDSE and DHuS1 with prioritizing DHuS data source if the demanded product is available there. Since DHuS software is being deprecated in favor of GSS, GSS connector will be further implemented and support for DHuS will be removed.
