5.3.1 Accuracy Check for Grid Resampling
Exercise Title: Accuracy Check for Grid Resampling
Author: Murray Brown
Version: February 2013
1. In Saga, load the global sediment thickness grid (sediments_global_ngdc_sdat) and the 0.1-degree resolution Liberia dummy grid, or the 1-degree resolution Liberia dummy grid -- either one is fine. Then resample the global grid to the dummy grid.
2. If you used the 1-degree dummy grid, this is what you must see (ignoring the specific colors).
3. If you used the 0.1-degree dummy grid, this is what you must see (ignoring the specific colors).
4. Use of other dummy grids must produce figure like these, with appropriately different resolutions.
