Hi All,

Some LOLA products for the PDS release (#5), which will be officially out on March 15, 2011, are now available on the LOLA PDS node !
Label files and documentation are still being worked out, but I thought it'd be good to post (and some of you know we usually put those products online a bit early)

The data released are from July 13, 2009 to January 31, 2011.
There are EDRs/RDRs (individual profiles) for the courageous ones. But most of you will prefer the map products ( http://imbrium.mit.edu/DATA/LOLA_GDR/ ).
In addition to IMG products (int16), there are JP2 files (GeoJPEG2000) which are compressed (lossless) and contain projection information. If you use a GIS programs, that should be helpful. The attached XML files contain the statistics already, which could save you 10+ minutes for the bigger grids upon loading. (Due to PDS filenaming conventions, you need to rename them to file.JP2.aux.xml for that to work properly; tested on ArcGIS).
And keep in mind that in both those formats, the data were digitized at a 0.5m granularity, so you will need to divide the values by 2 to get the actual heights (in meters).

Also of interest for visualization are the updated LOLA texture packages for Celestia.
ZIP files here: http://imbrium.mit.edu/EXTRAS/CELESTIA/
and a few screenshots:







It'd be great also to know how this community is using the LOLA data, so please reply if you do:
1- Experimental Data Records (EDR) [raw telemetry]
2 - Reduced Data Records (RDR) [altimetric profiles]
3 - IMG Gridded Data Records (GDR) [maps]
4 - JP2 Gridded Data Records (GDR) [maps]
5 - Celestia Virtual Textures


Enjoy !!

Erwan

I realized there was a mistake in the level 0 normal map. (The files were the same as the topography texture...)
The ZIP files have been updated. In case you downloaded the "old" version, you can download the two level 0 files here instead of re-downloading the ZIP.
