i've attached a clip from the 1943 army corps/usgs topo sheet from Oahu (Waianae). Does anyone know what the circled symbols are? They appear on the 1928 and 1943 series maps, typically along roads, trails, and powerlines, and sometimes between two buildings, but not always connecting to other segments like a telcom network would. There could be a military component too, as what i'm looking at goes over Kolekole pass and connects Schofield Barracks with Lualualei. I can't seem to find any reference to them in the current DRG symbology. If you know that would be dandy.

P.s., my best guess is a telegraph cable.

Look here for aeronautics: http://www.sddot.com...ory_symbols.asp - Powerline

For marine: http://www.fao.org/d...0E/T0390E33.gif - Telephone Line

Verdict? :blink:

Nah, that's pretty good. Telephone seems more likely is guess, only b/c there are the standard dot, dash dash dash dash powerlines already all over that map.

can you verify whats up and over that ridge on top left (circled area) today?
Is there still any sign of overhead cabling? I wouldn't imagine it would be underground then.
Maybe some old poles/ pole stumps still in ground.
Obvious question is there reference to them on a legend?

no, no legend. it's a USACE/USGS product that doesn't have legends on the map. just as the USGS DRGs don't today. that would be too simple. <_<

i'm going with telephone lines, and assuming that since it's 1928, they weren't part of a connected network, but rather functioned from one point to the other.

Hi Rob

Your guess is correct, it is buried and overhead cable. I am attaching two files. One the original 1944 USGS bilingual legend for Military maps and the second is the cut out of the specific symbol. Have a look.

Sorry I could not get the original file uploaded. An error on big file size pops up and the upload gets aborted. I have uploaded the file on my website, click on the link http://www.mapsandlo...m/maplegend.jpg to view the full legend of USGS Military maps of 1944.
