HI everyone.
I've been following MSL's meanderings since Day One, but I still find myself going to HiRise. I just realized that on the HiRise image info pages they list the map-projected & non-map projected North Azimuth at some angle other than 0 degrees; e.g., 'Map Projected North Azimuth - 274'. 'Non Map Projected North Azimuth - 103' And yet, when I overlay either HiRise image on Goggle Mars, a line drawn parallel to the sides of the imaged surface will extend up to the North Pole. Does this mean that Map Projected North is located toward the left side of the image instead of toward the top, and Non-Map Projected North is toward the right side of the image? And if so, what's up with the GM overlay? I hate to bother ya'll if this is a really 'duh' question, but my google-fu just isn't as strong as I thought it was. TIA Bobby R. |

for draping the hirise images over a mesh
there is a blender plugin just for that also depending on what you are using for terrain ( MOLA will not work well !!! ) the set of programs that make up " stereopipeline " can drape the image over the point cloud |
