Problems with bilinear interpolation of a grid
...offered would be much appreciated! Firstly I'll describe my dataset. The data is a grid of the planet at 1 degree spatial resolution, with each grid cell containing a value describing a particular variable (e.g. population density) for coordinate pairs. The dimensions of the grid are 360col x 180row. The x-coordinates of the values within the grid are longitudes (from -179.5(W) to 179.5(E)) and the y-coordinates of the grid values are latitudes (from 89.5(N) to -89.5(S)). What I want to do is convert this 1 degree dataset to a finer resolution of 0.5 degrees, thereby quadrupling the number of...
