DAVALIEN - the DAta VALIdation ENvironment projects provides an environment for validating EO data. It is intended for quality assurance of EO data and data processing software.
There are three major use cases you can use the project for.
You can use it to define the expected output of your processing software and when you have reached the goal the environemnt will tell you.
If you have already developed a processing software, you can use DAVALIEN to ensure that when you refactor the code base or improve processing speed, you do not inadvertently change the result.
You can ensure that third-party software does not change unnoticed through updates.
If you want to try Davalien first you can use the small environement prepared for SNAP. It runs and tests a few processors.
You can download the environment, unpack the zip archive and install also the DAVALIEN plugin in SNAP. Now you can execute the environement from the command line and it will generate two report files, JSON and HTML. For details, please check the Getting Started Guide.
