WWII Map Coordinate system

Postby 199Punch » 07 Oct 2009 15:12

Hello,
I'm trying to translate some US WWII Europe maps so I can find some locations on Google Earth.
I'm not sure if they're NAD27 UTM or what. Maybe someone can help me out.

Here's two examples: 43.44 - 96.32 and 31.6 - 88.6 My guess is they're within 20 miles of each other based
on the artillery locations in my research.

Thanks

Check the margins for lattitude & longitude marks There may also be note for LL in the map legend.

Whats the interest in the map?

I have all the coordinates for the battery positions and German guns and with proper know how I could
find them on a period map. From there I could place them with Google Earth.
All I have are examples like I had in my first post. Other than that there's hand drawn battery position maps.
I'm concerned the projection they used was different.

Projection probablly was different. Let me check some notes for leads.

If they are British or US maps from World War II they are using the Modified British Coordinate System found on the GSGS maps that were issued at scales from 1:10,000 to 1:100,000 during the war (copies of the originals may be obtained through NARA, TNA, or IWM). Most of the locations in Normandy are in the French Lambert Zone 1, although some may be in the Nord de Guerre Zone. See http://www.echodelta.net/mbs/eng-welcome.php for a complete explanation and coordinate "translators" that allow you to convert to Lat/Long or plot on MapQuest.

Hope that helps.

Thanks a lot, this is a start. The maps are Lambert Zone 2 1:25000. Makes it a bit tougher than the examples they use.
How do I manage the decimal points?

Hope that helps.

The grid remains the same regardless of the scale. In this case it looks like the XY are 4344 9632 and 3160 8860. However, you need to find out what sheet is being used, which should be indicated somewhere on the original document.

My 1944 map sheet is 16/32 S.W. 1:25,000 within the larger 3H/4 sheet.

I have a 1961 map of the general area under Lambert Zone 2 but the map has a different system it's VII-19 Plouay 7-8.
