Unfortunately the Web based report builder UI doesn't seem to have been updated very well to reflect the data on the worldmap tables.
I wrote up a SWQL query that does find what you wanted though, the key is to left join it to the worldmap.point table and look for null entries
select n.caption as [Node]
,n.detailsurl as [_linkfor_Node]
,'/Orion/images/StatusIcons/Small-' + n.StatusIcon AS [_IconFor_Node], IP_Address, Vendor, MachineType
FROM Orion.Nodes n
left join Orion.WorldMap.Point wm on wm.InstanceID=n.nodeid and wm.instance='Orion.Nodes'
Where wm.latitude is null

Thank you for the SWQL query, this query worked for me. Appreciate the help.
