A question from a user:
From this it appears that:
1. Hist data must be geodetic/geographic, or
When one first adds a table/column to the map view, GR checks if the data is planar. If it is planar the actual extent of the data to extracted from the header record of the rtree index (stored in the mdsys index metadata). But this data is not useable for geodetic/geographic data so GR has to go to the user_sdo_geom_metadata entry to get the diminfo values.
In addition, if the data is not point data then GR automatically implements the sdo_filter pixel filtering. This can be turned off in Preferences.
Finally, to create a decent map extent for the layer, right mouse click, properties for the layer. Then tick the box marked “Recalculate MBR (next draw)”. This makes GR compute an MBR that covers only the data returned via the next draw query.
