I missed that Bob.
It appears that he was doing reconnaissance and was a surveyor, so high spots seem right.
The first line says:
Line Intervisible
That means
Intervisible \In`ter*vis"i*ble\, a. (Surv.)
Mutually visible, or in sight, the one from the other, as

The second line says:
Supposed to be intervisible with high ??
The third line says:
Interrupted by woods_____perhaps where the green dots are
And the last line is what you say:
Routes taken in the course of my reconnaissance
