Latitude is your position north or south of the Equator. Lines, or parallels, are drawn around the Earth at intervals. The North Pole is assigned the latitude 90Âº north and the South Pole latitude 90Âº south. Lines of longitude, or meridians, are drawn a little differently.

I am using latitude and longitude as well as Landsat data as predictors in my random forest model that aims to predict presence or absence of black spruce trees across a landscape. Latitude shows up as having high importance and you could see the impact of the sharp latitude lines in the mapped predictions. Also, using tunerF the mtry is optimized for only 2 predictors, latitude being one of them. Is my model underfitting?
