I'm starting a couple of large modeling/analytical projects and believe it's time I understood when and how to store data in postgres and when to use postgis. For the past dozen or so years I've applied GRASS to projects all data have resided in the internal data formats. This is new territory for me and I'd like to do it right from the beginning.
My base data sets (statewide) include a postgres table with 110,852 rows holding water well log data, and a set of (soon-to-be-imported) hydrography/hydrologic units .shp files with associated .dbf attribute tables. When it is appropriate to put all attribute data in postgres tables and associate GRASS with those? When is it advisable to use postgis?
