Script that imports the SRTM data in a PostGIS (PostgreSQL) database.

First run the tests that come with this script:

python test/

Then download the SRTM source files (635 MB for Australia):

$ python continent

(replace continent by Africa, Australia, Eurasia, Islands, 
North_America or South_America.

Second argument (optional) specifies from which tile to resume. 
Use full file name e.g. ''. Set to 0 start at the first file. 
Argument 3-6 optionally specify a bounding box: north, south, west, east.

Verify that the download went correctly:

python test/ continent

Unzip the files (adds 3 GB):
$ for f in `ls *.zip`; do unzip $f; done

Create a PostGIS database (you may need to change some things here depending on 
your system):

$ createdb srtm
$ createlang plpgsql srtm
$ psql -d srtm -f /usr/share/postgresql-8.3-postgis/lwpostgis.sql
$ psql -d srtm -f /usr/share/postgresql-8.3-postgis/spatial_ref_sys.sql

Create a test database:

$ createdb srtm_test
$ createlang plpgsql srtm_test
$ psql -d srtm_test -f /usr/share/postgresql-8.3-postgis/lwpostgis.sql
$ psql -d srtm_test -f /usr/share/postgresql-8.3-postgis/spatial_ref_sys.sql

Run script that reads files and puts them in the database.
Test it first:

$ python test/
$ python continent

Verify the result

$ python continent verify 

All altitude data should now be in the table 'altitude'. Enjoy.
You can’t perform that action at this time.
