Re: Scaling/size of geographical entities

I have added geographic modeling support to our ontology development 
tool [1].  This uses the W3C geo namespace but can be configured to use 
other lat/long properties as well.  In the absence of a "standard" for 
radius-like information to determine zooming, I had to introduce an 
optional property

http://www.topbraidcomposer.org/owl/2006/07/tbcgeo.owl#zoom

so that the map is moved to a suitable scaling if a user clicks on an 
entity.

This is not meant as a suggestion on how to solve this issue, but just 
an intermediate work-around based on the Google zooming.  I hope there 
will be a better solution in the near future.

Thanks
Holger
