"obis dataset impact report" vignette

[7yl4r]

I would like to try putting two indicator maps side-by-side:

1. indicator calculation including a particular dataset
2. indicator calculation excluding a particular dataset

I think this would be cool for dataset providers to see. Big datasets like the Reef Visual Census for the FL keys are likely to have significant impact on the maps.
