Squares on Mars pictures

It's the Columbus Crater

I agree they appear to have shadows which are in the same direction as the shadows around other features in the picture. In other words the light is coming from the bottom right corner and shining towards the top left.

Very odd.

If You have seen the weird movie Moon, there were these huge harvesting robots collecting rocks, which left the same looking lines and squares behind them.

Here's a link to Hella's triangles pic,

Those triangle pilots are sure scruffy at parking.

Another view of the triangles:

Artifacts of the process used to capture the images, nothing more.

Always interesting to watch the responces though!

Nice try!

I did find this odd though




weird how often these 'straight edges' crop up on the Mars photos

The images are DTM (digital terrain model) representations. They are created by combining two different images of the same area to create a stereo view to determine terrain elevations.

Yes, it certainly appears to be the case...

Which makes me wonder, Is this the best way we have to create terrain data?

Would it not be more accurate to overlay some kind of radar return data over the original image to obtain topographic measurements?

Surely, Stereo image topography combined with image integration seems a bit.... Shall I say... overly complicated?

Is there any reason why this type of data collection method is used, as opposed to more accurate methods?

Wow, S&F, very interesting images. If it is artifacts (stictching digital) how come there arent such flaws all over the image, different layers - Phage ?

Look at the very bottom right of this one ? Is that a starport/base ;-)
D TEEC

Is there Helium-3 on Mars just like there is on the Moon ?

Hey just looking at Google Mars, not sure if this has been posted before but what is this ?
A lake or a hole...if its a hole whats floating in the middle ?

28°58'35.10"N
174°52'0.27"E

If it's a computer file issue, wpuldn't it be consistent.

According to Skipper, everything that we see has been run through an automated "Intelligent Fogger". An AI that looks for regularities which it then disguises.
If this is true (Mars Anomaly Research) then either the machine was not used or the process failed to make seamless "corrections".

This is certainly interesting.

Bingo!

I was wondering if anyone would see that.

If these are indeed a digital artifact instead of an 'actual' artifact, then why are these not seen all over the craters?

And why in just some of the images...if it is something unique to the posh cameras on HiRise, we should be seeing these things often..which we don't.

Don't know what the hell they are, but i too see shadows from them, so they look as though they are actually there...or perhaps they are accidentally made to look like it.

To explain;

There was rumour floating around a while ago, about the time when McNASA happened i think, that NASA and others were going to implement a new hitech computer system for searching for and automatically editing out any 'undesirable' (unnatural) objects that may show up in in Solar system imagery.

Maybe..we are seeing this thing in action, but with screwed up settings.

The fact that they have terrain texture continuity within the rectangles and cubes, and the shadows from the edges, leads me to speculate that this anomaly is something that has been applied to the images, in post-processing.
The purpose being to cover something underneath, and to appear as though the 'patch' is a continuance of the surrounding terrain, complete with subtle highlights and shadow.

I'd hazard a guess, if this is getting anywhere near to what's what here, they'd NORMALLY certainly not stick out by miles looking like a collection of huge 'plazas' and complexes!

Maybe the settings were incorrect, and we see what we see...due to overcompensation by the algorithm.

Could be something else entirely. But we may have got lucky.

Where did you get that photo? That's an interesting feature for sure, but it would be nice to know how long it is.

The Mars Orbiter does carry a laser altimeter (MOLA) but its maximum horizontal resolution is about 150m. Stereo imaging by use of the high resolution images from HIRISE provides elevation data for much finer scaled features.

Remains of ancient martian farmlands? hehe

Funny this thread shows up, I was just looking at Google Mars last night for the first time and saw some odd things. At first I was thinking it was just a glitch and that maybe my net was slow. Im glad someone else has seen these strange shapes also.

If you look at the original images used in the stereo pair you can see what is "under" the processing artifacts.

As Phage pointed out

- Boxes Some DTMs have square areas that are usually about .5-1 m different in elevation from the surrounding areas. These are artifacts of the processing algorithms used in Socet Set ((c) BAE Systems). There may be goups of these boxes. They are almost impossible to edit out, so the user should look for such artifacts in a terrain shaded relief map before using the DTM for analysis.

Besides we already have WAY to many parking lots on this planet, lets not start putting some on Mars. Next thing you know there will be crazy shoppers waiting for the Olympus Mons Walmart to open.

I thought it was odd too.

Very straight and even line. Take with that, that this was out to sea..when Mars had seas, and one could imagine a harbour wall, or enclosure wall.

Nice one.
