Latitude and Longitude of gridded dataset
Q: Do latitude and longitude points represent the center of each grid or one of the corners. What part of the grid these coordinates represent? Do the .RDS data sets (which are matched to these points) contain different information from the raster grids (GeoTiff?).
A: The coordinate point locations do not have a specific relationship within a grid as the raster layers were created from the .RDS files and many of the raster grids draw on more than one point.
The .RDS and GeoTIFF are not identical two different formats of the same data. The .RDS contains the original values extracted from a model at both the locations of Meteo stations and a 1km unprojected grid. The GeoTIFF combines the data at these locations of extraction and uses a projection to create a spatial raster
