Hello,
I'm developing a website that uses the google maps API. The objective
of the site is to have users (which can login) to submit different
types of geographic data(markers).

I have a mysqlphp database to store the users information, however i
have been trying to find the best way to store the geographic data and
i'm having problems deciding. Even if this question is not directly
linked to the google maps api, if you could spare some minutes to help
me it would be very nice :).

In my first approach each user had an xml file for the geographic data
( so i wouldn't pass the limit of 1mb file of the api), but i wanted
to implement a function where users could select an area and all the
geographic data from all the users in the system which was on the that
area bounds would be displayed. This would imply i would open all the
xml files which is not viable.

I could put the geographic data on a database and this problem would
be over, however if i wanted to add the possibility of the user to
submit new kinds of geographic data (e.g a polyline or a polygon or
even other kind of object defined in a xml) i had to alter my
database, whereas using an xml this would only mean a new node.
Do u guys have any suggestion on how could i solve this problem?






 data where users can login and submit different types of data. They
can submit text comments about geographic data or simply insert
geographic data.
The inserted geographic data can be a simple gmarker or an array of
markers, for a gpolygon.
My main doubt is how to represent the geographic data in a php mysql
database or using an xml file per user.
>From this description it would seem a database would be the best
option for this problem. However if i would want to add a new type of
geographic data, e.g. a polyline, with a xml this would be very easy,
it would be just adding a new node. Whereas using a php/mysql approach
this would be a task that would require me to alter my database.
My question is if anyone has got a better sugestion


My question is not directly connected to the google maps api but if
anyone can help me i would be greatly
