ESA released new set of HRSC images from orbits 1225 and 1863, which are map projected and radiometrically calibrated. At this moment you have to get them through the PSA interface

Actually - I'm going to pitch for more like 12...and I've not highlighted them but there's potentially another 2 in there as well, possibly more. I used Blue, Green and nIR for these...
Blue START_TIME = 2004-12-25T00:55:56.360Z Green START_TIME = 2004-12-25T00:55:37.866Z nIR START_TIME = 2004-12-25T00:55:04.547Z So - given that the red image is 'leading' the blue by 52 seconds, the full res is 89.5 m/pixel, and I'm getting between 6 and 9 pixels of motion between thsoe two frames...I'd estimate a speed of between 10 and 15 m/sec in a SE direction - one problem would be figuring out how much of that apparant motion is because of the slightly different p.o.v. between filters - but I think 10m/sec is a fair estimation. Look at me, getting all scientific Sadly - they didn't do all the filtes for this obs, but there's a normal red, and an ND filter obs that I've not looked at, so I'll try and do the maths with those later - see how well it ties in with 10-15m/sec Doug |
