Aerial photos for nav?? availability
Hi,
I often see many opportunities for aerials pictures for the navigation.Example: during winter pines are green and the rest of the forest is transparent.
Any feedbacks or stories about this??
Thank you

Never used them for that purpose, too difficult and they have no grid reference or directional guide.
May be of value for route selection, definitely useful for targeting.

How about this? Up to 1m panchromatic resolution. A bit pricey, though. 
TR, ask the right people and you can have your grid lines at just about any scale you want.

I don't share that info with people I don't know.
I also prefer the contour intervals of a map for nav purposes till you get very close to a target.

Hi,
I am in an Arty unit, and we often use aerial imagery with grid and contours. But I am not sure it is availlable easily and fast.
But I dont think it would be very useful, until conventional maps offer enough information for normal nav.

Aerial Photos
Virtually all of the USA is at this web site:
http://terraserver-usa.com/
Play with it a while. When you get a zoomed-in image (up to 1 meter resolution) you can print, with an optional grid overlay.
For example, here's an interesting spot, about 6KM east of Hoffman, North Carolina:
http://terraserver-usa.com/image.asp...19396&z=17&w=2
Click on "PRINT;" and then "11" x 17" and click on "SHOW GRID."
You will get a gridded photo in Latitude/Longitude (In Deg-Min-Sec and Decimal Degrees) as well as UTM grid in meters (easily converted into MGRS). That should get you close enough for targeting purposes.
You can zoom out (to about 4 meters/pixel) and see some interesting triangular runways.
