This scripts drops all extended map_style keys in redis and regenerates
|
|
|
|
|
the XML caches in all the base ones to target the configured mapnik_version.
|
|
|
|
|
|
|
|
|
|
Optionally (with --convert) it also re-writes the CartoCSS if needed
|
|
|
|
|
to target the configured mapnik_version.
|
|
|
|
|
|
|
|
|
|
It is recommended to make a backup of the redis database before using
|
|
|
|
|
this script.
