WebJan 4, 2024 · When dealing with large amounts of raster spatial data, you will often find that operations become very slow to perform or just won’t run at all. Often this is the result of single-core processes or simply running out of RAM. Fortunately, in most situations, there is a solution to this issue. WebThe procedure is slightly long-winded, but. 1. Set up the two Spatial Reference systems. 2. Open the original dataset, and get the geotransform. 3. Calculate bounds of new geotransform by projecting the UL corners. 4. Calculate the number of pixels with the new projection & spacing.
