Hi,
I tried Udig. It is good, but the repaint of the map is very slow.
What datasets are you using, we are finding ourselves competitive on
such things as shapefiles.
I would like to know, if this problem is caused that Java is used, or bad
algorithm and if this problem will be solved.
Lets be more specific? Our painting pipeline can incorporate some high
latency data sources.
I noticed that all map is repainted.
Oh that, we did experiment with repainting just the content revealed
after a pan operation, but for things such as labeling the result is not
very good. A solution to draw just part of the screen (and still look
good) a tile cache or somesuch .... a good research project.
But I tried for example software Map Window GIS (http://www.mapwindow.org) and
this software paints only a missing part of map, when I use function pan for
moving map.(This software is not written in Java.)
Far enough, Java is not the problem here, only lack of time and a desire
to work with a range of content while drawing nice images.
