DeLorme challenges are based on finding caches on the various map pages of a road atlas. Most of the checker taggers are not from Oregon (many are not even in USA), so would not have access to the specific road atlas. We would need information about what areas are covered by each map.
Since the maps will be rectangular, it should be sufficient to provide north-west and south-east corners of the map. If there happens to be any page with two map segments on it, both would be required and can be combined by the script.
