I just rolled out a new experimental map service.
It will display a map on your device which is locally rendered using OpenGL. This allows you to smoothly scale and rotate the map.
Currently it is considered beta. The map style has some glitches, still being usable. The map area is limited to Thailand with a large buffer around it. So most of Laos and Cambodia is covered as well. It is currently static content.
It should work with every modern browser on the desktop. For Android please use Chrome.
please try it for yourself here:
The site is best viewed encrypted and with the HTTP/2 protocol. This gives you about 10% of speed increase for free.
I had measured this with the assumption of a 4MBit throughput and 250ms of latency. Any recent browser will select this protocol automatically.
I hope the speed increase is also visible for you. The page itself had a Google pagespeed ranking of 100/100 and a security rating of A+ by SSL labs.
Please let me know if this is the track to follow instead of bitmap tiles like on http://thaimap.osm-tools.org/
