Scaled and Curved   Leave a comment

With excellent help from a reader of mathgroup here is a scale model of the Northern Imbrium Basin.  30 degrees x 60 degrees, 4 pixels per degree data.

15 degree x 30 degree rectangle, 16 pixels per degree data.

Taruntius and Cameron   Leave a comment

The LOLA Science Team released more data to the Planetary Data System in March.  This is Taruntius with Cameron on its rim.  1024 pixels per degree data, reduced to 256, or 118.45 meters per pixel.  95km rectangle.  The lower-resolution strips are still present in the high-resolution data near the equator.

Imbrium Basin   1 comment

Imbrium Basin cropped from ldem_16.jp2 produced by the LOLA Science Team.  Autolevels in Photoshop has the effect of exaggerating heights and depths in the grayscale image.  The inner ring of Imbrium is easily seen.

From the cylindrical projection, a flat Imbrium.  1500km rectangle.

North and South   Leave a comment

North and South hemispheres of the Moon.  Resolution 1 degree per pixel.  Vertical exaggerated 4x so the texture is not washed out in the lighting.

Hevelius   Leave a comment

Cavalerius and Hevelius craters.  Rimae Hevelius at the lower right.  800 x 800 at 236.9 meters per pixel.  189.5 km rectangle.  The data is not consistent near the equator, so low-resolution strips appear.

Cassini   Leave a comment

Cassini Crater, edge of Imbrium basin and Caucascus mountains.  Aristillus and Autolycus craters in the bottom left corner.  128 pixel per degree source reduced 50%, 473.8 meters per pixel.  12.5 degree rectangle, 379 kilometers. There is a nice ghost crater north of Aristillus crater.

Clavius   Leave a comment

Clavius.  780 x 780 image using 400 meter per pixel data.  312 km.

From December, 2009.

Rutherfurd crater on the southern rim of Clavius generated using 100 meter data.  An 81 km rectangle.   At this scale the lower resolution stripes as well as some pointy artifacts (see Aepinus) are now visible.
