I have searched around but cannot find out whether what I want to do
is possible or not.
I have a number of smallish polygons (e.g car parks) in a kml file
which I am displaying fine on a map.
If the user zooms too far out though, it does not provide as good an
experience as if I were displaying
Its probably worth mentioning Google Fusion Tables has the ability to
do this geocoding for you too, and you can export the full results, or
subsets of the results as kml.
This is expecially useful if your cities are each associated with,say,
a state (or any other criteria) so you could query the
Thanks for your reply @bratlif, I shall mull over that during the xmas
break!
I cannot say I know how to implement that but shall have a stab at it
and come back if I cannot work it out, after all, this is how we
learn.
BTW, although I now have the capture and storage of Polygons working,
I note
@Ben Appleton said: "V3 implements something like Douglas-Peucker in
JavaScript. Are you sure you
need to pre-simplify your polylines? "
Ah, you could be correct there, I will look a bit closer at the return
values, I was just trying to work out in advance a problem I had
noticed in my test data.
Hi,
I have some edited polygons being submitted.
It is entirely possible for those polygons to contain a point which
lie on a straight line.
To illustrate my case : if you imagine a square with 4 lines and 4
points, and on the top line there is a 5th point sitting on that line
with exactly horiz
Sorry for the delay in replying to this thread, thanks for the input
so far.
@bratliff - thx, but I dont want an IE only solution.
@Albert_Sun
I have looked into storing the polygon in a Mysql table row as you
suggested, and yes, this looks a really good solution, with lots of
downstream benefit
I have done quite a bit of searching around on this group and just
thought I'd post my initial thoughts just in case someone can share
any heads up on what I am about to attempt.

PHP/Mysql. I'd prefer not to have to go out to G
Are you making sure that the url of the kml file changes on each call?

You could just be getting the same cached file you originally served
up a few hours ago.
It could drive you nuts!

It does not answer any of your questions exactly, but overall I'm not
sure if you need to have "queryable kml" such as can be stored in

I don't know your exact situation, but if your aim is to zoom in on
the kml set of markers so that only a limited number are shown which
equate to about a particular radius, then look at zooming the viewport
in to a known level.

Perhaps I should ask how can I manipulate just the bold text contained

Or, what is the div of the InfoWindow named?
But yes, hardwiring seems the only way round it

I like the simplicity and speed of the native InfoWindows in Gmaps3,
and understand that it comes at a price: a scroll-bar appears
dependent upon the map-size and so on.
However, can someone just confirm my understanding:

I have a number of features in separate kml files, all contained
within a pretty tight area.
I can load them up dynamically and this works fine, think of a road

However I don't want the viewport zooming in and out for these
particular features.

Thanks for the reply Chad.
I will give that a go and report back when I get chance - deep into
playing catchup migrating some features from v2 to v3.

work.

KML files have to be served from a publicly available server, you
cannot do this from localhost.

Hi,
It is pretty simple code which I just got this working, and wondered
if it really is the most efficient way of hiding a kml layer when the
user zooms out too far. I was expecting to see a setting in the kml
layer which would handle this kind of thing.
Given that:

Thanks for your courtesy in explaining all of that to me.
I do admit I am struggling to grapple with some kind of ball I have

anything else.
I'll read again with your comments in mind.
Thanks
