It is a little bit more complicated than it looks.
Game map is very large and so it can't be converted in real-time fast enough.
Generated map tiles are not as heavy as the map itself, yet they are updated constantly and so we decided to use server-side solution to display map.
After all this tool has been created for internal use and we share it as token of good will. Some of the features are accessible only for our guildmates.
I understand that it may not be convenient for use to use it with network connetion but that is how it works right now. There is no way to convert it to ASP.net web page yet. Sorry
