GAM kelp forest model Oslo fjord, 2010
Region: the counties Oslo, Akershus, Buskerud, ├ÿstfold, Vestfold
Number of field observations: 4187
Field sampling years: 2005-2009
Prevalence: 0.04
Presence / absences: 168 /4019
Method: GAM analysis in the statistical program language R, using "look up tables" and the "Grasp Extension" to transfer the predictions to ArcView GIS 3.3.
Number of predictor variables: 10
Information about the predictor variables: DEM, slope, curvature at detailed and medium spatial resolution with a 125 and 525 m moving calculating window respectively, based on a 25 m resolution DEM; wave exposure, longitude, optimal radiation index and aspect, all with 25 m resolution; and maximum current speed and slope of maximum surface speed, both with 300 m resolution but resampled to 25 m.
AUC internal: 0.98.
