[Geomoose-users] Auto-refreshing

Matej,
You need to:
1. Add a script reference to your gemoose.html:
<script type="text/javascript"
src="extensions/AnimateLayers.js"></script>
2. Create an animation object (in your geomoose.html is ok):
<script type="text/javascript">
var WeatherLayersAnimator = new AnimateLayersExtension([
'iastate/nexrad-n0r',
'iastate/nexrad-n0r-900913-m05m',
'iastate/nexrad-n0r-900913-m10m',
'iastate/nexrad-n0r-900913-m15m',
'iastate/nexrad-n0r-900913-m20m',
'iastate/nexrad-n0r-900913-m25m',
'iastate/nexrad-n0r-900913-m30m',
'iastate/nexrad-n0r-900913-m35m'
], 1000);
</script>
The above object uses Geomoose's 'mapsource/layer' syntax.
3. Add the mapsource to your mapbook:
<map-source name="iastate" type="wms" tiled="false"
projection="EPSG:900913" width="512" height="512">
<url>http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi</url>
<layer name="nexrad-n0r"/>
<param name="format" value="image/jpeg"/>
<param name="TRANSPARENT" value="TRUE"/>
</map-source>
4. Add a layer the animation to your mapbook:
<layer title="Weather Radar" src="iastate/nexrad-n0r"
status="off" legend="false"/>
or add a tool to stop/start the animation:
<tool name="animate_layers" title="Toggle Animation"
type="javascript" selectable="false">
ImageLayersAnimator.toggle_animation();
</tool>
Best Regards,
Brent Fraser
