Thank you for your reply.
I use lo2isis (http://isis.astrogeology.usgs.gov/Application/presentation/Tabbed/lo2isis/lo2isis.html
) to convert Lunar Orbiter ISIS2 cube to ISIS3 cube, then as you said, I use map2map to reproject the image using a map file as follows:
Group = Mapping
ProjectionName = Mercator
CenterLongitude = 326.0
CenterLatitude = 44.0
I downloaded gdalwin32-1.6, and translate the ISIS3 cube to TIF file. However, when I load it into ArcGIS 9.3 and defined its projection as the map file above indicated, the coordinates are not right. I mean, its latitude and longitude in ArcGIS are not the same with Google Moon at the same region. More worse, the distances measured by ArcGIS and Google Moon are not the same.
I hope to use the images to do crater counting.
Another question: I have another PC with Redhat 9 desktop, but when I enter "rsync -azv --delete isisdist.wr.usgs.gov::isis3_x86_linux/isis . ", it shows:
rsync: connection unexpectedly closed (697 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(150)
