Re: [Geoserver-devel] Problem with on the fly projection

[Nutsch, B. D. <bn...@nd...>]

Thanks Justin for the info.

I should have mentioned in my earlier post that after seeing the
correctly calculated extents within the GUI, then clicking Submit,
Apply, Save, when I go back to the FeatureType editor, those calculated
extents are gone, replaced by the original lat-long extents.  So I don't
think that this tool is working like it should.  Unless some other spec
file is storing this information for later retrieval by some other part
of GeoServer.

I did discover that I can manually edit the info.xml, restart Tomcat,
and then display my data in state plane.  However, there are some
issues, since I have to zoom completely out (I'm using the built-in
openlayers from the Demo interface) to see the map, and if I zoom in at
all, the map disappears.  When viewing the map, I cannot click on a
feature to get it's attributes. I can click a feature, but no attributes
are displayed.  It's as if the mouse click location is not being
re-projected.

So, maybe I'm mis-understanding the utility of the SRS stuff in the GUI.
The 'Reproject from native to declared SRS' suggests to me that it
should project on the fly, making the image from that WMS appear in that
projection on a client.  But perhaps it's something along the lines as
you suggest, not sure.

Thanks again, Bob
