Ocalasix:
I can guarantee that you are not alone....
I have talked to TH'er Store Owners who did not know!
AND!
These are the guys, people go to, to get information/equipment!
I once asked for a
Geological Survey Map, of a certain area,
This Store is in Arizona.
And!
The owner brings out a
Topographic Survey Map!
Nope!
No where close, to being a
Geological Survey Map.
In doing so, He
only demonstated(s) his level of expertise/knowledge.
But!
Back to your Questions
1... Basically, An Orthophotoquad Map, is a large, regular Topo Map
sized Black & White Aerial Photograph
It is GREAT! for showing the works of man, almost or even better than an
IR Map
2...An
IR Map is an
Infrared Map, which come in B/W & Color ...
b]
IR [/b] is great for showing
any surface area that has been
distrubed...
ie: A road, a mine/tailings, a trail, a cabin, a burial/cache, etc...
OR!
Anything that has
broken or disturbed the orginal surface !
On a B/W IR Map, ( And! Also on an "Ortho") the distrubed area shows up as a "white" or very light colored area/spot.
OR!
As in the Military, some "dude" walking around or hiding in a covered "FoxHole" / Gun position !
This just a very general explaintion...
I hope that it helped ?
Do you, Need more details ?
AND!As some people actually, believe...
Asking questions
Is certainly
Not! a Sign of
"Dumbness" It Is In Fact, QUITE The Opposite!Being that
no one,
and even tho my middle name
IS! wRIGHT :
I MUST Include myself, FOR! as my wife likes to point out !
"No one knows everything!"BUT!The Intelligent (& Open Minded) Person does/will
ASK Questions!
