Processing speed improvements
Processing of MODIS layers after download (i.e., scale and offset calibration, computation of Spectral Indexes and Quality Indicators) is now much faster.
As you can see in the figure, processing time was almost halved on my (not so fast) laptop. This was achieved by modifying all computation functions so to use `raster::calc()` and `raster::overlay()` (more on this in a later post).
Although speed is also limited by download speed and compression options, this will allow to save quite some time when working on large areas and with many MODIS layers.
