Here you can find the information you need.

The RAD in the name coding stands for "Radiometrically-corrected RDRs calibrated to absolute radiance units"

Unfortunately, unless I have exact corner coordinates, I cannot determine which features craters etc fall withing the confines of the picture. As I said, the Apollo ones promise to have corner coordinates, but I am a few days away from seeing if they live up to expectations. There are some Apollo photos which do not seem to have these corner coordinates too.

Mars pictures: I cannot determine which filters lyle.org is going to use, so therefore it is tricky to predict the file name. Also, if the photos are taken at different times with different filters, the time element of the photo name is unpredictable. Whereas we can determine by looking, the computer cannot 'see' which photos are the same. If you would like to propose a definitive method of determining which official photos go to make up the lyle.org ones, I can produce it programatically.

Excellent effort from your side. Tell us when you have a spot on correspondances.

A suggestion to your Mars Utility images site.

Convert NASA image coding to Lyle.org coding

Example

You input

1P139098156EFF2809P2267L2M1
or
1P139098219EFF2809P2267L6M1 etc ...

And the output is

1P139098156RAD2809P2267L256C1

-- This comes from the fact that at least these urls refer to the same image

The latest project I have been working on is to try and cross reference the positions of the Lunar Orbiter, Apollo metric(from space) and maybe some other photos where the corner coordinates can be estimated or are known.

I have done the Lunar Orbiter part and the Apollo part is going to be added soon. This is all very much an experiment to see if this is possible and is to show which craters/features/etc appear in which photos.

The data for the LO is not really very reliable and so I have 'bodged' it with an estimate from the central position. This will probably need some refining and may not work at all in some cases but the majority of cases can be very roughly calculated.

I have been on the unmannedspaceflight forum and asked a question about the Lunar Orbiter corner coordinates and it appears as if the atlas representation of the LO images and their positions are fitted into the atlas by an extrapolation and warping/morphing kind of process (as I understand it from what they said here). Although there is a diagram with each of the LO images mapped to lunar latitude and longitude, this does not appear to come from any reliable data which available (other than in pfd format which has been scanned from original typed documents). My hunch is that this data is not available because they do not want anyone like me messing about trying to fit features onto images via a calculation. This should be a fairly simple to get a rough idea of which features are on what images (approximate only because I do not understand the real proper calculations involved using spacecraft altitude, tilt, phase etc), but it can only be done if the reliable data is available in computer-readable format.

The Apollo photos do have corner coordinates given but it remains to be seen if the features that are physically on the moon are contained and shown in the photos as NASA say they are.

I have opened up a new web page for you all to go and have a try and the 'contact us' page which previously had a problem and di not work very well, now functions correctly I hope. Please let me know what you think and where this could be improved apon.
