I'm a GIS software developer. I would like to adjust manually a KMZ over Google Earth images scaling, shifting and rotating it.
What I'm wondering is a tool like the one in Google Earth to add a raster overlay, but to apply to KML/KMZ polygon, polyline and point tags.
Is there a software to edit KMZ file in this way (elements multiselection and apply scale, shift and rotate)?
Is there a software to import a KMZ, edit it in this way and export again in KMZ?
Or I'm also thinking to develop something myself, but I really don't know where I can start from (Google Maps API?)
