It's partly perspective (a lot of distant points appear bunched together), and I think it's also related to looking at the north polar region where craters may not be quite as obscured by plate tectonics, vegetation, etc.<BR/><BR/>Note also that the "marker" files in Orbiter are made by users, so it also depends on what source(s) they used and how completely the data was entered. <BR/><BR/>There is an old Google Earth overlay for impact events linked below - I suppose there may be something more comprehensive now.<BR/><BR/>http://bbs.keyhole.com/ubb/showthreaded.php/Cat/0/Number/71111/page/0FlyingSingerhttps://www.blogger.com/profile/12015886527228889332noreply@blogger.comtag:blogger.com,1999:blog-18052302.post-25467373671907073582008-07-04T07:49:00.000-04:002008-07-04T07:49:00.000-04:00Thanks.BTW is it just me or does the distribution ...Thanks.<BR/><BR/>BTW is it just me or does the distribution of impacts on this look non-random? Perhaps it's perspective causing things to look bunched.Mang (433rd)https://www.blogger.com/profile/03917086753736981397noreply@blogger.comtag:blogger.com,1999:blog-18052302.post-68880713398575111632008-07-03T23:14:00.000-04:002008-07-03T23:14:00.000-04:00It's a screen shot from Orbiter, a free space flig...It's a screen shot from Orbiter, a free space flight simulator that I often use for educational outreach presentations (for schools, scouts, libraries, etc.). I also write about Orbiter a lot on this blog. See www.orbitersim.com and also the links on my side bar including my (free) ebook for Orbiter, "Go Play In Space." Orbiter is developed by Dr. Martin Schweiger of University College London with support of many free add-on developers.FlyingSingerhttps://www.blogger.com/profile/12015886527228889332noreply@blogger.comtag:blogger.com,1999:blog-18052302.post-74996306521700115042008-07-03T11:58:00.000-04:002008-07-03T11:58:00.000-04:00Very cool image.How'd you do that BTW?Very cool image.<BR/><BR/>How'd you do that BTW?Mang (433rd)https://www.blogger.com/profile/03917086753736981397noreply@blogger.com
