WWJ and GeoRss

[vash]

I'm working on a GeoRss viewer plugin for worldwind. It is based on the GeoRssParser class that i found on the sdk but i add a other class to handle point because the base class only handle shape. I render this point as icon on worldwind.

I plan to release a first version today.

My coworker (pred) is working on a GeoRss editor based on worldwind

My first result with this georss : http://earthquake.usgs.gov/eqcenter/...s7day-M2.5.xml

[vash]

I have done a first version of the georss plugin.

How to use it :
1. Download georss_worldwind_plugin_v_0.1.0.jar and 32x32-icon-georss2.png

2. In your IDE, add georss_worldwind_plugin_v_0.1.0.jar to your project and classpath and copy the image file into the src/images/ directory

3. In BasicDemo.java:
- add this line to the layers array definition (line 10)
new BasicDemo.LayerAction(new GeoRssIconLayer("http://earthquake.usgs.gov/eqcenter/catalogs/eqs7day-M2.5.xml","EartQuake","",null), true),
- add this line to the layers initialisation (line 239)
if (action.layer instanceof GeoRssIconLayer)
((GeoRssIconLayer) action.layer).setWwd(wwd);

4. Save and run

notes :
- It can only handle georss stream with <geo:lat></geo:lat> and <geo:long></geo:long> tags. I will add support for <georss:where></georss:where> tags soon.

- It needs Java SE 6 jvm for support of desktop integration, indeed when you click on a georss icon the default navigator is opened with the url of the georss item. I don't know what appends if you try to execute it with Java SE 5

Edit : You can try it with java web start : launch the GeoRssReaderDemo with java web start

Yesterday i started working on a WW icon add-on loader and went pretty much the same route, except i read a local xml file - and i packed everything into one class. I used a couple lines of your code, but tried out another way to launch the browser that seems to work with java 1.5.

Check it out in this thread.

I see this is that line of code

Runtime.getRuntime().exec("cmd /c start " + icon.getUrl())

But this way works only on windows i think.

Yea... i doubt the "cmd /c start" will work cross platform.
It seems overly complicated to strart a browser from java without a helper package though.

In Java 6 it is simply a matter of calling

java.awt.Desktop.getDesktop().browse(new java.net.URI("http://www.worldwindcentral.com/"))

For previous versions of Java I think JDIC can help.

Desktop is what vash used, but i didnt want to add a 1.6 dependency for that feature... well not yet.

Maybe this is just a matter of issuing the right exec command depending on the platform, but from what i've seen of some helper classes it is much more complicated

Java does come with a simple HTML renderer(without javascript support etc.) which I have used in the past to make a simple java based browser.
