I don't have any formal education in GIS so I'm thinking that I'm looking for something that exists, I just don't know what it's called.
I basically have a large raster data set that will get re-sampled into a pyramid of various resolutions (1m, 2m, 4m, 8m, etc) Is there a way to generate the pyramid with gdal using a custom projection?
And once that's created, is there a way to run operations on specific tiles and save them in a new pyramid in an organized way that can be referenced later?
I'll likely have multiple derivatives and will need to be able to check for the existence of a tile in a derivative pyramid, if it's not there, then create it based on the original pyramid. the tiles that get selected from the derivative pyramid would be based on a polygon overlapping an index for the pyramid of some sort.
I hope this makes sense. If this is something that I need to build from the ground up, then maybe someone can at least point me in the right direction so I know more about whats already available along these lines.
I should also mention that the derivative tiles will be made up of data of a dataset with tiles of different boundaries. (Such as combining a hillshade with aerial imagery) all the pyramids will all need to be built with tiles of exact same boundaries as the original dataset.
