# Bulk convert shapefiles to geojson using ogr2ogr
# For more information, see http://ben.balter.com/2013/06/26/how-to-convert-shapefiles-to-geojson-for-use-on-github/
#
# usage: geojsonize *.zip
#
# Note: Assumes you're in a folder with one or more zip files containing shape files
# and Outputs as geojson with the crs:84 SRS (for use on GitHub or elsewhere)

# geojson conversion
function shp2geojson() {
  ogr2ogr -f GeoJSON -t_srs crs:84 "$1/$2.geojson" "$2.shp"
}

# unzip files and convert all shapefiles
for zipped in "$@"; do
  FOLDER="/tmp/${zipped%\.*}"
  unzip -o "$zipped" -d $FOLDER;
  cd "$FOLDER"

# You'd probably want to `mv *.geojson [path-to-git-repo]/` at this point
# so you could commit the file to GitHub
# Happy mapping!
