[mapserver-users] KML generation-partially working

[Smith, Michael ERDC-RDE-CRREL-NH]

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.

Hi Michael,

  I see your point. 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?

Thanks,
Sowmya.

You probably have to set your WEB / IMAGEURL to an absolute path since otherwise the kml references are relative and not picked up.

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

Hi Michael,

  I looked in to the KML file. 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>

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.
