I have recently freaked out a little bit about Martian maps of all sorts. And finally I was astonished with those highly detailed beauties that I list below. Nonetheless. some of them have huge inconsistencies (crater names) easily noticed when we compare the surroundings of Gusev crater. Enjoy:

You're welcome!
Closest measurement from MOLA gives 1626 meters, HRSC DEM with better coverage but with lower precision gives ~1660 meters. Best guess based on published data 1655+/-30 meters. I suppose that I will add elevations for every identified lander in future version of the map. BTW, according to HiView coordinates of Beagle 2 are 90.4303226,11.5270253. These are slightly different than values which Doug Ellison extracted from Google Earth (90.4295E 11.5265N). This very small difference gives location error ~500 meters. But I have no idea how precise HiView is but based on my experience with other landers I suppose that Google is worse than HiView. -------------------- |

I pulled my values from HiView also...which is worrying. From which image? I've used ESP_037145_1915. I tried to extract location again in full resolution and it gives me 90.43036115568,11.52698736394 or 90.43036543916,11.52698314553. And I used wrong number in calculation so it's not error ~500 meters but only 50 meters. That's relatively negligible error. -------------------- |
