I was looking for the best availble radar images from Pioneer Venus
I think I found them here
http://pds-geosciences.wustl.edu/geo/premg.../pvvenus/radar/

but when I use
NASAVIEW found here it would not open them.

http://pds.jpl.nasa.gov/tools/nasa-view.shtml

Anyone know why?
or know of a better place to find the best/highest res of pioneer radar original images from nasa?

thanks

NASAview ver 3.7 worked fine for me (see attached). Did you download the label file with the image you were trying to open? Each image has a detached label with the same file name but *.lbl instead of *.img.

Best place by far in my opinion:

http://www.mapaplanet.org/

You can define the resolution and the extent of the area you view. Just choose Venus from the picture menu... and of course you can do it for the Moon and Mars and other worlds too.

I downloaded the .lbl in same directory as the image but it didnt work.
Maybe I dont know how to use the .lbl with the image? I am not that experienced with .lbl

If someone can get it to work for them with the latest version of Nasaview 3.8 then I will know it just me. Let me know.
Or direct me how to get 3.7


Yes mapaplanet is great. I wanted to get though the best largest pioneer radar to fill in the gaps especially in the northern polar areas.
that site I dont think gives me the pioneer or the venera 15/16 that I think I need to fill in gaps.


Does anyone know where to get the venera 15/16 radar images taken of venus?
I thought I found them here
http://nssdc.gsfc.nasa.gov/nmc/datasetSear...perture%20Radar

to be used with the viewer found here

http://petermasek.tripod.com/venera15.html


but I just get sent in link circles and cant find them.
Any ideas? thanks

Sorry about that - I was not paying attention. When I suggested Mapaplanet I was thinking of Magellan, not Pioneer Venus.

The other thing to do is open the images in Photoshop or other photoediting software, as Raw images using the dimensions found in the label file.

If you are using Windows the new (beta) version of IMG2PNG can convert this to a 16 bit grayscale PNG image. See this thread for details (in particular the last message in that thread).

a question bjorn dose the new img2png work on the old img and imq from the `90's - i do not use it so ?
now from the label in the link in the ops post
these are 32 bit
http://pds-geosciences.wustl.edu/geo/premg...ar/pven001a.lbl
if all you want is a map
in a link someplace in my sig there is a rgb png map made from the venus radar data ( oops not there )
http://celestiamotherlode.net/catalog/show...p?addon_id=1100

but PDS-map-a-planet is a great source
also ncc1701d keep in mind that nasaview ONLY will export to a indexed 256 8bit gif

--- edit added too ---
however you might do better with the mg_3002 data
http://pds-geosciences.wustl.edu/missions/.../gxdr/index.htm
the gtdr ( topo),gredr,gedr,
the Global reflectivity data record
http://pds-geosciences.wustl.edu/geo/mgn-v.../mg_3002/gredr/
all 32 tiles

Yes, it can convert these old files (it even converts the ancient Mariner 9 and 10 files).
