Raster map reprojection (warping) with JavaScript and HTML5 Canvas image

I wanted to create something nice during the FOSS4G Code Sprint, and I ended up programing a prototype of the client-side raster reprojection implemented with the HTML5 Canvas, JavaScript and Proj4js. It is kind of port of gdalwarp into the web-browser environment.

To try it you need a web browser which supports HTML5, it means the latest version of one of the Firefox, Chrome, Safari or Opera.

Have a look at the demo: http://www.klokantech.com/labs/map-reprojection-html5-canvas/

It is just a prove of concept in this moment, but I am sure you will come up with plenty of ideas for practical application… post a comment! ;-)s for practical application… post a comment! ;-)
