# Note that you'll need a recent version of innoextract
# http://constexpr.org/innoextract/, one that can work with files
# created by version 5.5 of Inno Setup, the one in Ubuntu universe is
# not recent enough.  The version available at
# https://launchpad.net/~arx/+archive/release is good enough.

# sudo add-apt-repository ppa:arx/release
# sudo apt-get update
# sudo apt-get install innoextract
# chmod +x download-mapa-digital-shp.sh

# If you use a mac you should probably 'brew install wget' first
# The script will create a directory called 'mapa_digital' where all
# the shapefiles are located, if something goes wrong when dowloading
# be sure to delete it and try again

# Projection compatible with Google Maps
PROJECTION="+proj=longlat +ellps=WGS84 +no_defs +towgs84=0,0,0"
# wget command
WGET="wget -w 5 --random-wait --tries=2 "

# The mapa digital is available as 4 files
