Thanks

What do you mean by KML content i/o for OSG?

Kernel Mailing List is the only acronym I can think of for KML...

Most likely the google earth format is meant by this:

http://code.google.com/apis/kml/documentation/

might be interesting to see ...

OssimPlanet can parse/render a sizeable subset of KML

He's probably referring to the Google Earth mark-up language:
http://en.wikipedia.org/wiki/Keyhole_Markup_Language
http://code.google.com/apis/kml/documentation/

(Why K for "Keyhole"? Well, because that is the product that google
bought to make Google earth.)

I suppose it could be useful to have an OSG application read these
directly but I've always sort of seen it as an interchange format for
dealing with Google Earth, ie: you had something else and turned it into
KML. Seems to me that the "something else" is what you'd want to bring
into OSG. Of course, I know of at least a few places that are actually
developing geospatial content in KML. So it happens. <shrug> And is
probably off-topic anyway.

KML -> Keyhole Markup Language springs to mind

If I remember right, John Rohlf is the author of KML.
He, along with Jim Helman, are the fathers of the modern day Scene Graph
(i.e., Performer).
Ah, Geek Trivia!

We load GPS-like data (tracks, POI) through GPSBabel in our application:
http://petit-poucet.org and use VPB to automatically generate terrain
from Landsat,SRTM,DRG,... around it.

It tends however to overload our app because each track point has a
caption text.

If somebody wants to contribute, you are very welcome.

Also there can be confusion with KML and COLLADA as these at times are used
interchangeably by some and it confuse the heck out of me

And KMZ files support both KML and DEA and lets not forget wonderful OGC and
its adoption of CityGML

Confusion rains on down .....................

So the question is does OSG have KML support currently or just COLLADA ??

[Mike Weiblen]

Yep, I was referring to the google earth fileformat. Just exploring the
options for geospatial content. Thanks for the leads everyone.

OGR has a driver for KML: http://www.gdal.org/ogr/drv_kml.html

I believe someone just submitted in a new OGR plugin. Check osg-submissions. -gw

Yes, Cedric Pinson kindly submitted an OGR plugin, to use it you'll
need to preload the plugin via.

osgviewer -e shapefile.shp

I don't know if it'll handle KML though.

For those who love trivia, Don Burns used to work at Keyhole, in
between working at SGI and setting up Andes Engineering. I also
almost went to work at Keyhole... but decided to set up OpenSceneGraph
Prof. Serv. instead...

If I had you'd all have to be using Vega Prime, OpenSG or one of the
game engines by now!

Funny how the wobbly world goes around ;-)

 osgviewer -e shapefile.shp

I believe that should read:

osgviewer -e ogr shapefile.shp
