Wetland and watershed maps

You can see the location map of the study wetland and its watershed area by clicking on the wetland.geojson and watershed.geojson files on the /inst/extdata folder.

Model validation

A mutiple resolution goodness of fit assessment function mrgf was included in the library and has been performed for each validation year after Costanza 1989 and Kuhnert et al. 2005. We implemented the version modified by Kuhnert et al. in order to exclude NA values from the analysis. The maps needed to perform this assessment can be found on the inst/extdata folder. See resulting graphs:
