Hi, I don't know anything about how data in NetCDF files are organized, but intuitively, I would think that, for a general 2D array, the data at points [j,i] and [j,i+1] would be contiguous on disk. Is this right? (i is the fastest-varying dimension) I might also suppose that, for an array of size [nj,ni], that the data at points [j,ni-1] and [j+1,0] would also be contiguous. Is this true? If so, is there a method in Java-NetCDF that would allow me to read these two points (and only these two points) in a single operation? (Background: I'm trying to improve the performance of ncWMS by optimising how data is read from disk. This seems to involve striking a balance between the number of individual read operations and the size of each read operation.)
