Pedon PC Support Data

Download a new/empty pedon database whenever you want to start data entry for a new pedon database. This new/empty pedon database comes preloaded with up-to-date domains, ecological sites, geographic areas, and geomorphic features, but you will have to reload whatever plant lookup data you need into this new/empty pedon database.

Please note that the format of ALL Pedon PC support data files has been updated for Pedon PC 5.0. Therefore you will not be able to import any support data file that was created for a version of Pedon PC prior to 5.0.
