just took a look at

http://imbrium.mit.edu/DATA/LOLA_GDR/
the img's have a sep3 date

PS. for the count files( CDEM_ ) pds2isis tosses en error about the " SAMPLE_BITS = 2" - isis wants 8 ,16 ,or 32
small edit in the LBL solves this

as per Rick Sternbach question there is a MAC isis3

and for just using pds2isis then > isis2raw most of the data dose not need to be installed just the BASE system ( small install ) and some of the data files
CODE
rsync -azv --delete isisdist.wr.usgs.gov::x86_darwin_OSX105/isis .
rsync -azv --delete isisdist.wr.usgs.gov::isis3data/data/base data/

but you can remove the very large maps if space is an issue /isis_3/data/base/dems ~4.8 gig

Thanks; I looked into ISIS some time ago. Way, way, way over my head. - R.

Nice!
From the label LDEM_64.IMG is updated with observation up to June 27 and there is a new LDEM_128.IMG to play with smile.gif

i just imported the 128 into Nip2 and did a simple "emboss " filter
two screenshots from nip

the second is zoomed in a bit
still need some work but better than the last set

give it a year and it will rival the MOLA

Rick Sternbach and a few others i can post the 128 as a 2 gig raw image
500 meg north west,south west,north east , and south east
with 0 long and 0 lat in the center of the map ( -180 to 180)

--- rant ---
raw2isis has a bug, that i am about to report -- i would but the USGS is down for maintenance

16 bit unsigned ( my working format) gets saved as 32 bit REAL but the cubs say they are 16unsigned -- just a bit of an issue
and pds2isis is doing it too map2map is a MESS. telling isis it is 16 bit signed ( from the cube& img )when it is 32 bit float ( the data in the cube)

at least isis2raw IS WORKING the way it should
i have finally a 90north to 40 north ( polar), the same for the south pole and 45n to 45s ( simple cylindrical )
so i can clean them up a bit

John - That's a generous offer; thanks. Even the individual 500MB tiles would be fine in my case, as I'd be exploring smaller areas in Terragen or TG2. Eventually for rapid prototyping a physical globe, I'd be getting with the smart folks who have the computing horsepower to work with the .img files and grow the resin parts, but right now I'm hoping to "look around" the surface in 3D. - Rick

I'd like to see what results you obtain with Terragen. Post some of your picture when you have them.

Oh, and I just noticed a lot of file names *missing*, like all the JPG2000 files. With my limited Mac software here, those were the only files I could get to look at and use in Terragen. I can get a file like LDEM_64.img to open in MacDEM as I did with the MOLA files, but now MacDEM can't figure out the height range (I think). Image comes out where I can see the terrain with directional lighting turned on, but the shades are all super contrasty and black-white splotchy. Probably time to get a new machine and better terrain software. sad.gif


GeoJPEG2000 are forthcoming. We want to make sure they're correct, and we found some strange things happening with the programs used to make the conversion.
Anyway, release date has always been the 15th, if you can wait that long wink.gif

As for the 128ppd being too large, we did not plan on splitting those up, but that could potentially be done in the next release, if enough people think it's worthwhile. The problem is that when we eventually release a 1024ppd, we don't want to break them up 256 tiles (each equivalent to a 64ppd global). 64 "128ppd" tiles will be quite enough already!

not for me but to upload a zip to a service like zshare , they need to be small
so there is a plan to release a 368640 x 184320 pixel image 68 megapixle map ( 1024 px per deg. )

I see the new LDEM files with the "PPD" stuck in the middle, and I can open the 4, 16, and 64 JP2000 versions, but no way can I get the 128 to open in Photoshop, even with almost 1GB RAM devoted to the application and a healthy secondary HD. I get a message talking about trouble with a "file-interface module," which I have no idea how to fix. As before, I suspect I'd need a Mac Pro with 8GB of RAM to play in the bigger sandbox. Anyhow, I'm attaching a view of Copernicus from the 64 file, quick render in Terragen. - Rick

How are you guys processing the RDRs? I have found RDR2TAB and RDR2XYZ but they are for MAC only, has anyone found a win32 version? I have the fortran source code but no compiler.

Thanks for any help.

I'm using custom software to do it - on Mac, so can't really help there. Yes, most people are using the GDRs.
