In the first part of this recipe, we looked at the metadata of the prism raster table and a single raster tile. We focused on that single raster tile to run a variety of statistics. The statistics provided some idea of what the data looks like.
We mentioned that the pixel values looked wrong when we looked at the output from ST_SummaryStats(). This same issue continued in the output from subsequent statistics functions. We also found that the values were in Celsius degrees. In the next recipe, we will recompute all the pixel values to their true values with a map-algebra operation.
