Dear all, here I am with one question which I'm sure has such a simple
answer that I already feel embarassed in advance! Here goes anyway... I'm
trying to calculate the area length on a GeoTIFF file using GetArea()
method of OGRPolygon class and i'm not sure which is the unit that returns.

This is the information about the raster dataset

"GEOGCS[\"WGS 84\",DATUM[\"WGS_1984\",SPHEROID[\"WGS
84\",6378137,298.2572235630016,AUTHORITY[\"EPSG\",\"7030\"]],AUTHORITY[\"EPSG\",\"6326\"]],PRIMEM[\"Greenwich\",0],UNIT[\"degree\",0.0174532925199433],AUTHORITY[\"EPSG\",\"4326\"]]"

Thanks for your patience
