Hi everyone, I have an forest fire intensity asci file with 200m resolution which i need to be smoother and at 30m resolution. i convert the asci to raster then resample to 30m using a bilinear interpolation, but the resulting raster doesn't make any sense. what am i doing wrong? here is the original asci file if anyone wants to try for themselves...
Bilinear resampling usually works well when you are creating a more coarse resolution from a higher resolution. You are doing the opposite at a quite large difference (200m vs. 30m). Please try using the cubic convolution resampling method which might help. Note here that you might be merging two concepts: one is a resampling used to create the new pixels, the other is a display resampling mechanism. The geoprocessing tool you run will still create square pixels and when you zoom in you will see square pixels if your display resampling is nearest neighbor. So, in addition you can change the display resampling to bilinear which might give you a display that you are looking for. I hope this helps.
