# Bash script to create a new postgis database and prep it with GADM

|
# Basic workflow:
|
| 7 |
|
|
# 1. Create postgis-enabled template db
|
| 8 |
|
|
# 2. Create postgis-enabled db from the template
|
| 9 |
|
|
# 3. Create required tables in postgis-enabled db
|
| 10 |
|
|
# 4. Load gadm2 and geonames.org data into database
