Less then that it works fine... 100 is approximate number... i would want to insert more then 2000points... i have checked the data and it looks fine... do you know what could be the reason? nice day Primoz Hi,

I'm going to implement this class into an extension for CMS TYPO3, using rggooglemaps. nice work. I tried different tools – this is still working, THX.

Any suggestions? Thanks, Dianbo Hi, there are 1000 lines in my application (a topology graph) rather than one line with thousands of points. Any suggestions?

The drawbacks I can see is that it's a bit more work to update the information in the database and also if you in the future want to use the data for some other purpose in a context which does not support encoded polylines.

Hey there Gabriel,

I’m working with encoded polygons both using your PHP port and the original Javascript version of the dpEncode utilities.

Everything works great, however am having issues using my complex polygons within Google Static Maps. I may be SOL (Sh*t out of Luck), but no hurt in seeking some advice.

Basically when using a simple encoded polygon things work fine. However when using a complex encoded polyline (72 points used to plot a radius circle) I get nothing but problems.

Pretty sure that the underlyiing issue is that the Google Static Map API does not allow me to supply the encoded ‘zoomLevels’ like the JS API does (using GPolyline.fromEncoded).

This Works

While…

This does not

I’ve also tried passing the points to the static maps but of course the request URI is too long.

Encoded Polyline:

Something tells me I’m trying to do way too much with the Static Maps.

About load times, I am not so sure if polyline encoding really improves performance if you already have zip compression enabled on your server (for example using zlib.output_compression in .htaccess). By the way, on your server there are a few things to be optimized, according to YSlow... Interesting article, and nicely written.
