WhooTS : Rack, Ruby + mini WMS → TMS Proxy

Whoots is the tiny public wms to tms proxy

Its a simple WMS to Google/OSM Scheme TMS proxy. You can use WMS servers in applications which only use those pesky “Slippy Tiles”

Installation

You need :

• Ruby!
• Rack (gem install rack)

Usage

• Gives OSM/Google Tiles, not true TMS (maybe later)

http://example.com/tms/z/x/y/{layer}/http://path.to.wms.server

defaults to png. Optionally pass in ?format=image/jpeg for jpeg e.g.

http://whoots.mapwarper.net/tms/z/x/y/{layer}/http://path.to.wms.server?format=image/jpeg

Notes

• Gives OSM/Google Tiles only, so make sure the WMS server support EPSG:3857
• Doesn’t do any caching.
• See public/index.html for more examples and help!
