Hi All,
We've been working on some tools to perform routing using PgRouting.
Currently we are using a MapGraphic to display the way points the user
has selected and the resulting route.
This works well, however in the tiled rendering system it leads so some
less visual pleasing results. The mapgraphic has to be re-rendered
everytime the user pans. This is not so nice as all the other layers
are cached as a part of the tile and only re-rendered under specific
situations.
So, I've been experimenting with using TemporaryResources to display the
way points and resulting route. I'm creating two TemporaryResources
(one for lines and one for points) and updating the features in the
layers as the user modifies waypoints.
I'm wondering if anybody has any advice for me on using
TemporaryResources vs MapGraphics. Is using TemporaryResources a bad
idea? Are they meant for something else?
Thanks,
Emily
