GDALers: What is the most efficient way, given a "reference raster", and an arbitrary raster (we'll call it "unsynced") synced together to allow them to be stacked: the output of this should be the unsynced raster with the same number of rows, columns, pixel size, upper left coordinates, and projection as the reference raster.
Here are the assumptions: - both rasters already have the same pixel size and projection, but the offset of the upper left coordinate may not be "perfect" - for each pixel location defined by the reference raster, the output should have the closest (nearest neighbor) pixel from the unsynced raster. It should have some NA value in regions where the reference and unsynced do not overlap. Thoughts? The application of this would be e.g. taking a set of Landsat images from different time periods (each image has slightly different numbers of rows and columns), and stacking them together to perform time series analysis.
