Chile in GeoJSON format
Taken from http://siit2.bcn.cl/mapas_vectoriales/index_html/
To convert from a shapefile object to GeoJSON use
ogr2ogr -f GeoJSON -t_srs crs:84 [output].geojson [input].shp
You can also simplify the input:
ogr2ogr -f "GeoJSON" -t_srs crs:84 -overwrite -progress -simplify 2000
and crop the precision of the waypoints:
sed -E -i 's/([0-9]{2}\.[0-9]{1,4})[0-9]*/\1/g'
4 decimals will give you ~11 meters of precision.
To pretty-print a Json file:
cat [input].geojson | python -mjson.tool
To pack a pretty printed file I'm using Underscore:
underscore print --in [input].geojson --out [output].json --outfmt dense
