specific coordinates to cast charts

[Guest guest]

Dear Professor, SATVA members,

 

Could anyone comment on the virtue of using the actual coordinates of

the place (room) of birth to cast charts? Nowadays, GPS receivers

available to the public can be accurate up to 100 meters.

 

My guess is that for smaller locations/cities, the difference in

coordinates would not be that significant when compared to the

coordinates available in places like www.astro.com.

 

Many Thanks,

 

Jorge
