<font color="yellow">What we can do is take the orthorectified map that RCH used and make a new map w/ the new data. We should be able to eliminate much, if not all, of the 5 degree error that I said would be there from the beginning. (lolol, well at least to within Plait's 1 degree of error.) </font><br /><br />Reasonable? Yes. <br /><br />Can we do it? Look at the "anchor point" post above of the "D & M" (Which, BTW, was tongue in cheek...I was making a good natured point about alignment of higher res with that photo.). How are we supposed to determine, with any degree of accuracy, the location of features to properly align the "pyramid"? That's the key to the geometry...we've agreed on that.<br /><br />That was my point...do you want to try and overlay the high res features on that photo? Do I? It would be painstaking and time consuming....and since only one of us apparently has PhotoShop <img src="/images/icons/wink.gif" /> I guess I know who's going to be the one spending hours making sure its aligned properly. <br /><br />Here's a question we haven't answered, and, perhaps it is the key to the whole "rectified/non-rectified" question. What was the difference between the two photos? Did positions change? Did it make a 1 degree difference? A two degree difference? No signficant difference? I would think someone at TEM should know - especially since they apparently believe it's significant..<br /><br />And, lastly, I have to ask...if the rectified photos are of such importance, why does TEM use photos you contend are "non-rectified" (i.e., anything other than '76) to demonstrate the geometry of the "D & M" and its relationship to other features? Seems to me, and I'm not trying to be argumentative here, just making a point - you can't have it both ways. Unless, of course, they've already produced what we're talking about doing....or have aligned any photo they use on the site with the '76 data....<br /><br />Why not use the same material RCH uses on TEM to ma <div class="Discussion_UserSignature"> <strong><font color="#3366ff">Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild.</font> - <font color="#3366ff"><em>Tennyson</em></font></strong> </div>
