Hi Barry
I need help with the following.
1. I need to plot markers in google earth approx 10 000 lat and longs from an XML format will be great if the icon can be changed along with color
2. For each marker I need it to be representative of a 250meter circle
3. When plotted will give me a form of coverage map
4. How could I then break it up into segments where if x numbers of markers exist in a segment then can color the region in as red , yellow, orange for high med low .
5. Appreciate your help on this

Thanks for maintaining this site – it’s been really useful for my walking group, in which some members like to be able to convert an OS grid reference to a postcode for their satnav.
Also, since multimap.com has been unilaterally replaced by bing.com by microsoft, there isn’t now an easily accessible mapping web site that accepts a grid reference directly (bing.com can’t cope!), and your site gives us a fall-back method for providing map links for people.

Hi,

I’ve tried to use your very useful KML Placemark Sorter tool but unfortunately, my KML file is larger than your 500KB limit.

Please let me know if you have any alternative ideas how I might go about sorting the waypoints in this file.

Thanks!

Hi Barry your co-ordinate converter is brilliantly simple, I have been using it to convert my GPS locations degrees/mins/secs N/W to SE numbers for my finds locations suitable for my FLO on the PAS scheme, but it seems to have stopped working? is there a problem with it at the moment? Cheers Dave.

Hi, been working on Google Maps to create a bird count map for two counts I now manage in Wisconsin (umm, no, not part of Great Britain). Your circle map maker is a lifesaver, as I need to draw a circle to encompass our count area. The tips say such a map can merged into another My Map. For the life of me, I cannot figure out how to do so. Any help much appreciated by me and the other volunteers!
Thanks,
Brad

AFAIK that is deliberate. Google dont cache the ‘loader’ because it’s used for stats tracking etc. But its a small bit of code anyway so shouldnt really be an issue. The actual full API that it goes onto load should be cached tho.

Just to clarify – I would have thought the browser would use a cached version of the maps file?

But it doesn’t (seems to be the case across all browsers too)

Thanks!

Hi there, I have employed your dyanmic script loading example (number 4 I think)


 var script = document.createElement("script");
        script.setAttribute("src", "http://maps.google.com/maps?file=api&v=2.75&key=&async=2&callback=" + callback);
        script.setAttribute("type", "text/javascript");
        document.documentElement.firstChild.appendChild(script);

For me the client is forced to reload the script each time, any idea why? Is it something to do with dynamically adding script to the body
