Hi Andrea,
Thank you for your response.
Here is an example of a placemark which isn’t in the right place:
The lookat and the point coordinates are different (I would think they should
both be in the lat long range of 49->60-124->-117.
The layer config is listed below after the KML output..
Thanks again!
Michelle

Hi All,
I have an issue with the KML Reflector in Geoserver 2.8.1.
Is there any way to get the KML Placemarks to work properly in this instance…
The data is SDE 10.2.2 in Oracle 12c, EPSG:3005….
The raster output displays properly (zoom in as there is scale dependency) and
the placemarks are returned but they are not located properly.
Can you be more specific about the location error? How big is it, does it look
like a translation?
With a datum change in the middle, from NAD83 to WGS84 (used by Google Earth),
some offset is to be expected, althought
normally between those two is really small.
According to epsg.io<http://epsg.io> the best transformation accuracy would be
4m:
http://epsg.io/3005
If you have some sample points to test, one can check the transformation made
by GeoServer, using
the transformation console (in the demo section) with the proj4 one.
E.g., I've tried a random coordinate in the valid range of EPSG:3005 (according
to the epsg.io<http://epsg.io> page),
first using cs2cs (based on libproj4, e.g., the same used by QGis):
> cs2cs +init=epsg:3005 +to +init=epsg:4326 -f %2f
1000000 2000000
-126.000000 62.994224 0.000000
and then the same coordinates with the GeoServer reprojection console, which
returns:
-126.0 62.99422426150637
Seems to me there is a very good match with the two tools, does not look like
there is a bug here.
Sometimes a large offset is due to the data being advertised in one CRS, but
actually stored in another.
Cheers
Andrea
