I've been trying to change the initial default extent of the search map in Geoportal such that it begins at the contiguous US rather than the entire world. I'm using one of Esri's online map services and I've read in other places that adding the following line to the InteractiveMap tag within the gpt.XML file allows for doing this:
initialExtent="<xmin;xmax;ymin;ymax>"
I have tried it with decimal degrees (lat/long) and also with the coordinates reflective of the basemap's WKID. The Geoportal application seems to ignore this entry, though.
