I have a thousand raster tiles in un-projected decimal degrees from which to build a seamless mosaic in a metres-based coordinate system. The final image will be about 70,000px by 50,000px. Which is the better approach, thinking in terms of processing (time) efficiency and quality of result:
أكثر...
- mosaic into a single image and then transform to the finalprojection?
- or transform each tile and then mosaic?
- (or don't mosaic at all and use a virtual raster table in thefinal projection?)
