I have been thinking about Surveys and the standards people set to release them. Currently, it seems that maps are handed out based on feelings. Would it make sense to add a section to a survey report to compliment the section that describes the map quality. This would enable people to see the rational purpose of the cartographer. If the cartographer states that the map will not be released for other purposes, a person seeking a map of the cave may decide whether they have another purpose that is significant enough to warrant re-mapping, or whether the current map with distribution requirements meets the needs of the community at large.
Example
Cave Name: Example Cave
Description: The following is the map of Example Cave as surveyed by the Science Team.
Cartographer: Mapmaker Extreme
Map Quality: This map has a quality of XX as defined by NSS mapping standards.
Notes: The owner of the private entrance has (or has not) requested that this map not be released for recreational purposes. (Note: this would require that the cartographer has good enough ethics not to lie about this.)
Release Authority: The map may be re-released only for the following groups/purposes
1) Builders needing to ensure they don't build buildings on top of caves
2) Rescue teams who will use the map only for the purpose of a rescue
3) ...
Agreements required for release:
1) All recipients of the map must agree to destroy said map after the completion of their approved task
2) All recipients must agree, under penalty of law, not to copy or distribute the map without cartographer permission.
