We are proud to announce the release of the new SwitzerlandMobility mapping website using MapFish Framework
Many functionalities are available:
* ergonomic design
* large amount of pregenerated base layers (aerial and national maps provided by swisstopo)
* around 50 layers that are concatenated with TileCache
* layertree with groups and radio buttons
* advanced tooltips
* high quality print
This website takes advantage of amazon web services as cloud computing infrastructure.
Eric Lemoine has just written an interesting blog regarding the usage of Repoze to secure Tilecache.
Two nice improvements have been made in Tilecache:
- TileCache can now convert the image send to the browser from the original format (defined in the configuration file) to a format specified in the WMS request. This feature has been developed for IE6 because this old browser can’t handle transparent png files. If you want to support this feature, configure your OpenLayers WMS layer to something like:
new OpenLayers.Layer.WMS(”admin”, “http://www.example.com”, {
layers: ['A', 'B', 'C'],
format: OpenLayers.Util.alphaHack() ? ‘image/gif’ : ‘image/png’
});
And don’t set the alpha option to true.
Remember that this feature is time consuming if a format conversion has to be made
- If several layers need to be merged, OpenLayers can do that. But, this merge process is time consuming on the client side. Tilecache is now able to do that on the server side and let you build performant application.
