Export Placemarks Data

Hi
There is no export features, you can easy to do it.
All data saved in database tables.
As for my GoogleMaps extension it names like '%_zhgooglemaps%' start with prefix.

You can install my extension to the other site, check that versions the same.
After that just use MySQL to export appropriate table (without DROP table) for example in SQL format. After that import this file into new database (by MySQL too).

* _zhgooglemaps_maps - table for map definition
* _zhgooglemaps_markers - table for placemarks
* _zhgooglemaps_routers - table for route definition
* _zhgooglemaps_paths - table for paths
* _zhgooglemaps_markergroups - table for groups
* and so on

You can edit your sql-files to change/remove some data. For example, you want to change reference to the other map.
It is text files and it is very easy to change it.
