so i have 'save as''d the new project and layer with my new Custom CRS project string being '+proj=laea +lat_0=70 +lon_0=0 +x_0=0 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs'.
However when I calculate area using the field calculator the numbers still don't make sense. Some of them are even in the negative. I have included a screen shot of the layer I am trying to calculate area for. Please note the column titled 'Area_Km2' are the original areas and the column titled 'Area m2' are the new areas which I am trying to calculate.
FYI I am working with a merged layer and I only clipped area in one row namely that titled 'Va2', It should be the only one with changed values. I am assuming the area will be in meters from the definition string.
