Re: [udig-users] Show features one by one

[Jody Garnett <jody.garnett@xxxxxxxxx>]

I have been wanting to introduce a time slider into uDig for a while :-) Perhaps we can ask a Summer of Code student to do it...

You may also be able to do something from the user interface now - you can try this and let me know:

- open up the style for your shapefile

- change the settings to nothing (ie no fill, no color, etc...)

- open the table view

- select the features one at a time using the table view; and watch the current selection show the features one at a time

To make a user interface to do this kind of thing a little nicer:

- make a ui that changes the layer LAYER__DATA_QUERY in response to next and prev buttons

The programmer documentation for LAYER__DATA_QUERY is here:

Hi people,

 

I need to do like a fire simulator and I have already the shapefile with all the features that tell me how the fire spread among the time. So I have one feature for a particular hour, another for the next hour, and so on. What I am trying to do is, once I have the shapefile uploaded from Geoserver, click on a "Next" button and show the next feature on the map.

How can I draw features one by one from the same shapefile? There's some way to do it?

 

Thanks a lot

Sebastian
