Mars' Hale Crater -Anomaly!

Extensive image analysis showed, that no image processing algorithm is known, that may have created the said structures systematically or by chance. Cosine transform/inverse cosine transform (DCT/IDCT) artifacts - so called JPEG pixelation - must be disregarded, since uncompressed TIF imagery is available and detail resolution (raw data unit DCT blocksize) is mapped down to about 2x2pixel. Map colorization programs follow given 2D/3D landscape attributes and are not known to create highly organized, distinctive, geometric patterns on their own. Possible patchwork artifacts (mosaics) can be excluded, since the images in question were taken in a single stripe shot by Mars Express' NADIR- and high resolution stereo camera (HRSC).
