And all those sweet sickly kind words and then you shafted me - banned me without telling me why.

Well, I am NOT going to take the programs down. They are still there, and you can all still use them whenever you like.

I am not going to stoop to your level and you can continue with your forum without any more help from me.

Ok, as a special treat for you all, since it was my dad's bithday today(when he was in a body), I have found sol details and programmed them.

Now the filename decode will give you the Sol number as well!!

If you do not have the website Chandre, you can enter "http://www.example.com/' and then the filename then .jpg and it will work on that. It does not care what the domain name is (the http:// part of the URL). Try the new Sol part anyway, I think I got it right, but it will need some people to use it before we all have confidence in it.

Coming soon - a Date to Sol and Sol to Date calculator.

Whoa gmantoo...you're talking to a non-tech...disbelief

I found a post that 25 June 2005 for Spirit was Sol 525 so I worked out that Spirit Rover 13 June 2005 was Sol 514. (and it was). I do not know the official way but that worked well for me. If we could pull images from the same camera on the same sol it would be wonderful !!!!

Humanoid and Xenon may be able to give more input on this one ?

If we could just input the basic image number as saved to your computer when you download from the official site and it pulled up the details and a sol number than we could actually just go and look at the sol ourselves, we would not need the images of the day...but if we could have them it would be so much easier for all of us to examine our anomalies in more than one image...

If you can describe to me how to do it, I can produce one.
The problem I can see is that we have to know where to look(which site and in what page) to find out the names of the files so that the program can search through them one-by-one. How did you arrive at your solution?

I have done the same thing many times, and I could not go back to the site where I found it. Sometimes the names have been changed or extra things added to the end of the filename which makes a ggl search not able to find other similar photographs. (http://areo.info/mer/opportunity/2172/tn/1P321006692EFFABMIP2386L5M1_L2L5L5L7L7.jpg.html) Sometimes, I even change the name myself to make it more meaningful and then I have no hope of ever finding it again!

Example:
http://marsrovers.jpl.nasa.gov/gallery/all/1/p/2171/1P321007029EFFABMIP2386L5M7.JPG

How do I work out what should be the next/previous photograph in this sequence?

Also....
How do you work out the sol? Thats what I want to know please.... see my Sol post!
If I can work this out, then I can at least give you the photographs taken on the same Sol perhaps?

What would make me dizzy with delight is a programme that allows you to insert one image number and that gives you the images taken immediately before and after it... that would speed up research.

I'll give you an example. I downloaded and image while surfing, number only have no clue what site I used. Found something interesting but could not get back to the same area. Used you programme today to get a date and time then manually worked out the sol so I could go onto the official site to raw images and search the sol for other pictures...what a timely process....bleh

Hope it proves useful. Is there anything else we need? I have been thinking of trying to show the rover pictures in thumbnails rather than just those silly list boxes. You have to click on each one to see what is inside and I think that is a terrible waste of time.

Hi gmantoo, just a question, decode to what? If to detect source, I get that from the URL, if to convert to different format or ??? Whatevevr the answer Ireally appreciate ur effort and time in creating a program. Cheers
Thanks. I wanted to know the date the photograph was taken on and the place where it was taken. Although I have not found a list of codes and places that the Rovers have been, this info is in the filename.

Currently, you need to make sure that you dont have a space at the front of the URL (otherwise it does not recognise it properly). Anyway, the readout looks something like this for the Sol 1 Pancam example URL
=========

This photograph 2P126471510EDN0000P2303L5M1 is version 1 of a photograph produced for M - MIPL (OPGS) at JPL on Sun, 4 Jan 2004 06:57.
It was taken with the PANCAM, through the Left camera, using a 535nm (20nm bandpass) (green) filter on the Mars Rover Spirit.

It is a Downsampled EDR picture which is raw, is NOT liniarised, and is NOT thumbnail sized

The picture was taken at site number 00 on drive number 00, and the command sequence number P2303 to take the picture was instructed by PMA & Remote Sensing instr. (Pancam, Navcam, Hazcam, MI, Mini-TES) and belongs to the group 2000 through 2899 - Pancam sequences

Moderators: Feel free to put this topic where you think it will be useful.

I have written a program to decode the Mars Rover file names. You just have to enter the complete URL of the photograph and it should pick up the bit before the .jpg and decode it for you. Currently it does not work for urls ending in anything other than .jpg, but I am still working on it.

It would help if you could notify me of any problems you find.

Hope it is useful and any feedback is appreciated.
Thanks.
(edited to change url)
