The Koppen Climate Classification is basically a shapefile that says what is the nature of the climate in a certain grid on the map in the world (e.g. for latitude A and longitude B, the climate is tropical). This can be downloaded from here: Data Catalog (for years 1976-2000).
I also have a dataset dividing Nigeria into 774 regions, called LGAs. This can be downloaded here: Shape file of Nigeria - Shape file for Nigeria - openAFRICA
Each of the 774 LGAs in Nigeria will have many grid points from Koppen. Therefore, every LGA may have one type of climate (if all Koppen grid points in the LGA have the same climate), or more (if different climate grid points in the LGA have different climates).
I need help coming up with a dataset that says for each of the LGAs what the climate is. If an LGA has more than one climate, then choose the climate with the most grid points within the LGA.
Any help is appreciated. Thank you!
