Thanks for providing the zone names! Exploration Determination is already in the map system, and the following code will add Temple Crater. I personally don't have access to Temple Crater so I couldn't get the zone name on my own.
Code:
<ImageStyle Name="exp21_dun_western_wastes_raid_02" displayname="Western Wastes: Temple Crater [Raid]" zonerect="-1582, -1148, 1408, 1075">
<ImageFrame Source="images/maps/map_exp21_rgn_western_wastes.dds" SourceRect="0,0,800,600" />
</ImageStyle>
