MapSnack – your fast map viewer

I’ve tested AJAX based approach for displaying maps on web page. I took sample area north to Brno  20x 20 km covered by various geodata including VHR IR images. I had to intercept HTML requests to  map server to see what it takes to generate map of particular range and layer. (I had no access to map server, nor I took care what mapping engine serves maps, but it was not in format of WMS). I found quite simple prototype of AJAX display on mike page and I bend it little bit to work with geographicaly referenced maps (actually I needed JTSK system used here in Czech Republic). Conclusion is that AJAX approach for map display has lot of potential since is is elegant, extensible and transparent for end user (just save your page and you may run locally your client or include your client on your own page. Also more about AJAX vs. Flas approach for map displaying see David Blasby’s blog On my sample you may zoom in/out and pan. In zoom level 4 you will get IR aerial images. tested on IE6 and NN6.
enjoy it…
