# Bash script to download geoscrub_input table dump (created by AMK) from the

# vegbien database, and load it into the geoscrub database (i.e., the

# postgis database prepped with geonames.org data, GADM2 data, and

# associated mapping tables).

#

# Won't be necessary if we end up injecting all of the geoscrubbing and

# geovalidation functionality directly into vegbien itself. And if we

# end up implementing this stuff as a standalone service instead, we'd

# need to rethink (and generalize) how the input data is handled. But

# for now, this should at least serve as a placeholder that could be

# tweaked manually to load any arbitrary geoscrub input data table.

# before running this script.
