<div dir="ltr"><div><div>Hi Rabah,<br><br></div>The image size is going to be constrained by the amount of memory on your system, and at 524288**2, I calculate 270G pixels!! While there are a number of other factors that can limit the amount of memory available (user limits, older versions of NCL were 32-bit, etc.), I might expect you could at least double your 16384**2 image size.<i> </i>I suppose you could construct your large image in pieces and then tile them all together into on large image, but not only will that be a bit tedious to manage, I am also unaware of what out-of-core image tools might be available. Finally, I don't know much about Google Map internals, but I would think it could deal with tiled imagery (?)<br>
