Re: [udig-devel] animation for temporal data
|
Hi Dale, we have considered add "time" to the ViewPort model for a while
(following the guidelines used by the WMS specification). We have not
done this yet - as you are the first person to ask.
Here is how you could do it today:
1. place "time" on your style black board (it is a parameter that will
help choose which resource & renderer to use)
2. make a "style configurator" that has a slider (and a play button
backed by a Job?)
3. associate the shapefiles together using the catalog friends extension
point
4. now that the layer has access to time and all the shapefiles you can
either:
- Choose the correct Shapefile via via a layer resource post processing
hook (jesse has the details); or
- copy the shapefile renderer code and have it ask for the correct
shapefile directly
Having this as an example would help provide the real world experience
needed to place time into the ViewPort model properly.
Cheers,
Jody
Hi
I have a bunch of shapefiles representing temporal data (wildfire
growth on an hourly basis).
How might I go about automatically animating them -- ideally just by
specifying a basename
for the files and a timer for updating the current file. Saving the
animation as a movie
would be a nice bonus :-)
Thanx
Dale
