[ka-Map-users] Handling large raster data sets

[Lorenzo Becchi]

Sten, sorry I maybe sent you in the wrong way,
today I've visited your site in heavy traffic (maybe) and it was  
doing totally different things than tonight.

I've seen what you describe in your first mail, it seems really  
strange to me.
Did you change any part of the code?

your GMap works perfectly
http://www.cmis.no:8080/index.html/index.html?map=gmap

Cmis map works fine, heavy but fine
http://www.cmis.no:8080/index.html/index.html?map=cmis

but if I call
http://www.cmis.no:8080/index.html/index.html?map=cmis_raster
it start doing the mystic part...

It gets a "layer has no properties" error on kaMap.js line 1441
that means:
1440    var layer = this.aMaps[this.currentMap].aLayers[0].domObj;
1441    var img = layer.childNodes[0].style;


now from your init.php:
...
aszScales=new Array 
(750000,500000,250000,125000,75000,35000,15000);var map = new _map 
( 'cmis_raster', 'CMIS_Raster', 0, 3, aszScales);map.setDefaultExtents 
(-730393,6442169,1523378,8132498);map.setBackgroundColor('rgb 
(255,255,255)');map.addLayer(new _layer( 'GRIDS', false, 100,  
'jpeg',false, new Array(1,1,1,1,1,1,1) ));map.addLayer(new _layer 
( '__base__', true, 100, 'jpeg',false, new Array 
(1,1,1,1,1,1,1)));map.resolution = 72;this.addMap( map );
...

the only thing it seems strange to me could be the GRIDS layer  
visibility set on false.

I'm quite tired (going to bed), not a  great fantasy, but try to put  
in on. Maybe that old bug Tim solved?
or try to change position in the mapfile at  layers (first place to  
second place)

Best: try with new CVS, remember to change config.php map array to  
the new format

ciao
Lorenzo
