The size of that map (in 24bit colours) should only be 480 kb uncompressed. Not such a large download. Their maps must be larger and have higher resolution than that?

480kb? per square km maybe


The scale is about 2cm = 1km.
(@ 2.5m /pixel, 400 pixels per km)

A km^2 is 160,000 pixels (and 4cm^2 of map)

If using 16 bit colour we have 320kB per squ km (or 480kB in 24bit colour).

An A4 photocopy (at 100%) covers about 15 x 10 km = 150 squ km.

so: 150 x 320kb = 48,000kb or 48MB

If 24 bit colour: x 3/2 = 72MB
If 32 bit color: x 2 = 96MB

A full chart is about A1, or 8 A4 sheets:
16 bit: = 384MB
24 bit: = 576MB
32 Bit: = 768MB

Imagine re-downloading SPWaW 1-3 times for each map.....

A SPWAW 100 x 200 hex map (representing 5 x 10 km = 50 km^2) would need a file of

50 x 320kB = 4.8MB (16bit colour)

I'm currently working on obtaining a set of CD-ROM's that cover Europe, North Africa and Southwest Asia

Good news! Does the "Southwest Asia" cover any of the pacific island groups? I have a special interest in WW2 from the pacific point of view. These would be very helpful.

In my "Guadalcanal" campaign (to be released in about 3-4 weeks) getting topo maps and photos of Guadalcanal was VERY difficult. Eventually found the data but put me back nearly $50 in cash.

Good job.

If I can ahold of those maps I'll piss my pants. I'll be more than happy to burn 10 copies and send them to people. Damn. Now I'm excited.

Gentlemen: Unless I'm much mistaken and my memory is failing a little, but did not National Geographics have maps available for that period (pre 1939 through 1946)of the ETO area...I know I read it somewhere that some of the invasion maps were from them????
I guess I'll have to go to their site and look around.

Seems that once again, National Geographic comes through. I know that in several other cases the US military has used National Geographic maps in operations. During the thirties when the Marines sent a couple officers into the pacific (sorry don't remember if it was "Bud" Edson or not), the initially used National Geographic maps and then modified them with their observations about harbors, landing facilities, etc. Also, I beleive NatGeo maps were also used for North Vietnam during that time and even as recently as Grenada in the 80's.

Guess those folks make one heck of a map.

Jepp, that makes sense. I was a little bit lazy not to calculate for the WHOLE map. Seems like a fullchartmap will just fit on a CD...

From what I understand from my buddy it is a series of CD-ROM's. I'm not exactly sure how many as I've never seen the entire set. I know they do exist for almost teh whole globe it's just a matter of finind the ones without the military information on them and sending me copies. I'll post more information as I get it.

Wild Bill: Here's the map answer I promised you....go to .....http://www.nationalgeographics.com/reso ... /.....then scroll down to On Line Map store, highlight maps logo, (box)...new screen...below search, hi lite CD ROMS, on drop down Hi Lite Maps...new screen three offers down. I'm sorry this seems simplistic but I don"t know how to send an URL to you....I believe this is what you want. :0

I have a strong suspicion that the maps offered by National Geographic aren't detailed enough for realistic terrain representation.

Tomo

Tombstone: I assumed the requirement for these maps was for features unavailable in modern maps ie: town/city sizes, roads which may or may not exist today. Terrain features are probably close to 1940s even today so a modern map would probably surfice, but if terrain is shown I believe thes maps have a zoom feature. Well either way good luck.
