[Geoserver-users] Problem with Geoserver forcing WGS84 on image pyramid

Hi all:

I created a image pyramid using gdal_retile.py on a series of 3642 images creating many thousands of geotiffs at 4 levels. I then created a datastore using the ImagePyramid plugin in Geoserver. I am having a couple of strange issues I can’t figure out:

  1. I’ve created a large image pyramid (30000+ tiles) in EPSG:26918 which is NAD83/UTM Zone 18 N. Using gdalinfo the individual tiles have the correct SRS as do the index shape files. The geoserver layer also has this same SRS defined in both the native and declared SRS. However, when I add this to ArcGIS as WMS it only displays in WGS84. This issue does not happen when I use a smaller set of tiles.
  2. ArcGIS won’t display the WMS layer from geoserver at the default extent, it only appears once I zoom in.

The WMS layer works in google earth but again not at the default extent of all tiles. I need to again, zoom a bit and manually refresh the layer.

I suspect this may have something to do with the pyramid that was built using

Any ideas would be appreciated.

Thanks

Mike
