# First, make a dump of the database without data (-s)
$ pg_dump -h localhost -U username -Fc -s -f db_dump dbName

# Create a list of the functions

Python script to convert DBF database file to CSV

• First download dbfpy: http://sourceforge.net/projects/dbfpy/files/latest/download?source=files
• Then install: sudo python setup.py install

To convert DBF file to CSV:

./dbf2csv database.dbf

Ingredients

• a decent DEM
• gdal
• some computer

compute grayscale hillshade using gdaldem

gdaldem hillshade -compute_edges your_dem_file hillshade.tif

color-ramp to compute transparency (alpha channel)

In another bowl, prepare the following shade.ramp file:
