Webmap fine-tuning

Posted by robotnic on 20 April 2010 in English.

Hi all

Many of you maybe already know the khtmlib map library.
Some people give me feedback, that some settings are not correct.
The biggest problem is to configure the zoomspeed for mousewheel.

I don't have a usability lab. This is open source software and I can't
invest money in professional testers and hardware.

For fine-tuning I need your help.
Have a look at
http://www.khtml.org/osm/v0.47/config/
There are 9 parameters to adjust. Please try to find settings that work
on your computer. If your settings are ok please press the "Publish Config" button.

The configurations are sent automaticaly to my webserver.
From this informations I can improve the software.

Microsoft presented the first beta of internet Explorer 9.

What das it mean for Webmaps?

Direct2D will speed up map rendering:

opensource map:

(webkit is good on that)

Hardware accelerated SVG will allow to use vectorgraphics as map overlay.

New Zoom Zoom Zoom map

Posted by robotnic on 15 March 2010 in English.

As already announced in the mailing list, I have a new map online. It's a complete new implementation and does not use openlayer map library.

I developed it for webkit browsers including iPhone. For iPhone I had to use hardware accelerated image rendering to do proper moultitouch.
Chrome and Safari offers also hardware acceleration. Firefox and Internet Explorer announced to support Direct 2D.

With faster browsers a smooth zoom is possible. Try to load some images to the browser cache by zooming in and out. The zoom by doubleclick should be an animation with at least 10 frames/sec (fullscreen).

Please try this in an webkit browser. Opera 10.50 has also very nice speed.
It's still Beta and internet explorer and konqueror are not supported.
Firefox works slower but will speedup in 3.7 Version. If you have 3.7 alpha you have to enable the 2d css.

New Slippy Map

Posted by robotnic on 8 December 2008 in English.

Hi all

I made a new Slippy Map.
The new thing is, that it's possible to zoom in an out very fast.
At least at my computer it works excellent.

Turn your mouse wheel at:

http://lamp2.fhstp.ac.at/~lbz/beispiele/ws2008/oomap4/index.php

On my 1 GHz Celeron Laptop it zooms with about 15 frames/second.

I tested it with Firefox 2.0, Internet Explorer 6.0 (Linus/Wine - strange error with missing tiles), Opera, Konqueror (no wheel mouse support) Ubuntu Linux.

Keycodes, mouse scrollspeed, ... are maybe different on different system - it's a beta version.

Feedback is welcome.
