Tutorial demonstrating method of minifying raster data

[benlaken]

We often need to convert raster data from scientific datasets into lightweight versions meant for fast loading tiles. We should detail some standard methods of extracting and minifying (i.e. making the files lightweight).
For example, we can document how we would perform an ad hoc/per project assessment of what information is essential for a dataset to maintain, and what detail is not necessary, and a corresponding description of how to subsequently convert values into different formats (e.g. like mapping continuous temperature measurements into 256 integers), and saving the data as unsigned 16-bit integers, and finally compressing these data.
