Orchestrate WASP (Weighted Average Synthesis Processor) to create monthly syntheses of cloud-free reflectances for sentinel-2 or Venus Level-2A products distributed by the Theia Land data centre.

For more details about WASP: WASP github repo and cnes website.

Installation

1. Download WASP binary zifile, unzip and copy it into the root of this repository.

2. From the root of this repository in terminal, run

   docker build -t wasp .

Usage

First, you need to download Level-2 products of your choice or prepare by yourself using MAJA. If you don't know how, have a look at WASP github repo and maja_peps repo. Make sure they are unzipped. Then put them in a working directory(/path/to/imagery) e.g. l2a_maja. Then choose a centered date(date) and the half time interval for synthesis (synthalf. Then run:

docker run \
  -v /path/to/imagery:/mnt/input-dir:ro \
  -v /path/for/synthesis:/mnt/output-dir:rw \
  -it wasp date synthalf

Note that the folder mounted at /mnt/input-dir needs to contain all Level-2 imagery will be used for calculation. Results are written to the folder mounted on /mnt/output-dir.
