I have a simple array (not geo-referenced in any way) in Matlab (which is not a language I know a huge amount about...so I can export it to other languages if needed) which has the dimensions 180 x 360 and contains data for each 1 x 1 degree area of the globe. I need to calculate the area of certain cells in this raster.
Obviously the area will vary based on longitude, but I have no idea how to calculate this area, particularly as my array is not georeferenced. I saw a reference online to the
area function in the R
raster package, but I'm not sure how to get my matlab data into a
Raster object within R.
Does anyone have any suggestions as to how best to calculate these areas?
