[ka-Map-users] Drawing routes in ka-map

[Peter Giencke]

Brent,
 
Nice. How easy is it to remove the route after it's created? I can see a
user clicking on an area, highlighting it, and removing the highlight from
the previously clicked entity. Oh PS, the page isn't loading in IE because
you didn't close your style tag <style/>.

hi, i've been tinkering with this, finally got it working--still some bugs:

javascript for polyline class at:
http://128.32.253.220/draw/polyline.js
perl GD script at:
http://128.32.253.220/draw/polyline.pl.txt
example at:
http://128.32.253.220/kamapdev/htdocs/index2.html

i have drawn polylines with 16,000+ pts and it works fine. there seems to be
no problem even if the images are fairly large--though things get a little
slower, it is probably better to use w. zorn's library for extremely large
polylines. or at least break up the image....

also, as it is now, all points are stored in the polyline object. there's a
better way to do it but it involves more accounting and i haven't got around
to that yet.

Paul, et al,

What are the prevailing thoughts on how to draw routes as overlays in
ka-map?

The number of points and be quite extensive, especially if someone
generates a route across the US.
