Tracing of altered natural features would also be useful, although
infrastructure is of more importance for the moment

Any further questions, please ask.

[1] we're not sure where or how yet - perhaps someone can assist here

likes of 'date_on' be appropriate here? please advise if you can
suggest the most suitable tags to use
