diagonal linear features
« on: November 16, 2011, 11:52:07 am »
Hi
I found some lovely linear features today on an image.  (see attached)

ID: AMZ1000eou
Latitude: 20.3422°
Longitude: 30.8404°
Sun Angle: -73.29°

The problem I had was that I couldn't rotate the interesting feature box.  In the end I made a couple of big boxes that covered everything.

Is there a way of rotating the interesting feature box?

Yeah, i believe there is a triangle shaped yellow object which should allow you to rotate it.

You can change its shape with the "handles" but not rotate it. I think some changes might be planned along those lines for a future version.

Also to save you having  to save images you can just right click and paste the image location code between the IMG tags. More info here. :)

How do boulders make tracks?  Is it a heating/cooling thing? similar to that in death Valley?

I've just seen the boulder tracks section in another part of the forum...no need to answer my questions....

Hi Pete

Boulder tracks are formed when an impact occurs and boulders are ejected from the impact site and may roll quite a distance across the lunar surface. Boulders are also sometimes dislodged from crater walls by moon-quakes and roll down the crater slope.
See the boulder tracks Image of the Week posting for more info:  Boulder Tracks

and What causes erosion on the Moon?
