My take:
-The pokeball turns matter into data, the pokedex scans the pokemon data to identify genetic traits, species family, etc.
-Makes estimate of habitat from the Morphology of the pokemon
-Cross references with local region folklore, studies and academic data on the internet
-Compiles Pokedex entry based on all of this.
This is probably the best answer. Though the question why the people of that world can only turn pokemon matter into data and not all matter will probably never make sense.
