Hi(gh)!

A new attempt at getting a simple cylindrical elevation bitmap of Vesta suitable for generating a mesh2 with POV-Ray...

Whenever I try the USGS cloud processing of file Vesta_Dawn_HAMO_DTM_DLR_Global_48ppd.cub, I only get a ridiculously small zip file (only a few kilobytes!) containing either a strange XML description or a tiny little bitmap about 10 by 5 pixels... what do I wrong?

I first click the blue "Process button", then log in, then choose options as following:

Name or Label/Job Name: Dawn HAMO DTM Global 93mp: Apr 2, 2015
Name or Label/Job Description: PNG conversion of Dawn HAMO DTM of Vesta
Image Options/Single Band Image: yes
Image Options/Output Resolution (meters/pixel): 92.72061651 (default)
Projection/Projection: Input Projection
Projection/Extents/Max Latitude: 90
Projection/Extents/Min Longitude: 0
Projection/Extents/Max Longitude: 360
Projection/Extents/Min Latitude: -90
Download File Format/PNG, 8 bit (for the time being - later on I would also try out GEOTiff)
Download File Format/Percent Stretch/Minimum: 0
Download File Format/Percent Stretch/Maximum: 100
Download File Format/Graticule, Grid Lines: No Grid

Then I click on the blue "Add Job" button and wait about 5 to 10 minutes...

...this time (!) it almost worked well (possibly because I chose "Input Projection" rather than "Simple Cylindrical"), I in fact got a zip file of about 6.5 MB, containing a huge greyscale PNG of 17280 bx 8641 pixels... but...

...right through the center, from pole to pole runs a white gap, 17 to 18 pixels wide. As fixing this manually would be a no-go, I ask you now what I can do to get rid of this... could it be because of the non-default stretching?

See you in Khyberspace!
