You said "So I have an image corresponding to this symbol in ms_tmp". Do you actually have a valid png image at /ms_tmp/502a9927_2bc4_10.png?
The way KML output works is that the temp symbol images are generated and the the kml is written and the kml refers to those images. If the images are, in fact, valid, then its a path problem as I suggested earlier and the IMAGEURL is not absolute and pointing to your IMAGEPATH directory location. If the there is no file in /ms_tmp then its probably more of a permission or space problem. You should be able to see exactly whats happening with LAYER and MAP level debugging. See http://mapserver.org/optimization/debugging.html and set the DEBUG level to 5.

But, the images itself are blank. So making the paths absolute has no difference. When the output format is png, I get all the layers rendered correctly. But when the Output format is set to KML only, the image outputs from each layer are coming blank :(. So any inputs regarding this? Has anyone else ran in to the same situation?

And please, reply to the list, there are others that can learn and respond that way.

It looks fine. But the Images which have been generated in the ms_tmp files are blank. There was an image for each layer, which came out to be blank and for my layer 'ControlPoints' I gave under class ->Symbol-> Circle. So I have an image corresponding to this symbol in ms_tmp which is being used as the styleUrl in the KML. yet I am seeing a cross mark for that place mark in the Google earth. For the layer 'sbet' - it is a line, so there is no image generated at all and this layer is being displayed good on the Google earth. LAYER NAME ControlPoints #Photogrammetric points DATA Photogrammetric_Point STATUS OFF TYPE POINT CLASS STYLE # Symbol to be used (reference) SYMBOL "circle" # Size of the symbol in pixels SIZE 8 COLOR 190 20 190 # Outline colour (RGB) - black OUTLINECOLOR 0 0 0 END END PROJECTION "init=epsg:2246" END END KML : <Style id="style_symbol_circle_8.0_ffbe14be"> <IconStyle> <Icon> <href>/ms_tmp/502a9927_2bc4_10.png</href> </Icon> </IconStyle> </Style> <Folder> <name>ControlPoints</name> <visibility>1</visibility> <styleUrl>#LayerFolder_check</styleUrl> <Placemark> <name>ControlPoints.0</name> <styleUrl>#style_symbol_circle_8.0_ffbe14be</styleUrl> <Point> <coordinates> -84.61444330,38.04278949 </coordinates> </Point> </Placemark> -Thanks, Sowmya. _______________________________ Sowmya Tiramdasu QCoherent Software 9668 Madison Blvd., Suite 202 Madison, AL 35758 (256) 461-8289 Telephone (256) 461-8249 Fax www.geocue.com<http://www.geocue.com/> From: Smith, Michael ERDC-RDE-CRREL-NH [mailto:[email protected]] Sent: Tuesday, August 14, 2012 10:37 AM To: Sowmya Tiramdasu Subject: Re: [mapserver-users] KML generation-partially working Have you looked inside the KML file? You can also set a DEBUG value on your layer (and mapfile) and look for anything that might be interrupting your KML write. Mike
