[mapserver-users] Need examples of UTFGrid Mapserver + Ol3

[Seth G]

Hi,

I also tried to get an example of the UTFGrid working with OL3. I was 
using MapServer running under IIS on a Windows Server, and after 
debugging it looks like there is a problem with MapServer/Windows and 
text encoding that causes the UTFGrid output to be corrupt.
I have created a pull request with a fix for this issue at 
https://github.com/mapserver/mapserver/pull/5342
Are you also using Windows?

You should be able to see the browser requests/responses using Chrome 
developer tools, Firebug for Firefox, or Fiddler. At least then you will 
know if MapServer is returning useful output.

Regards,

Seth
