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 EDIT 2011.02.25 08:30pm EST 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. |

Very nice! At the bottom of the Celestia page you have the non-tiled false-color topography images. Could b/w shaded relief versions be added to that?
(EDIT - actually what Doug asks for works for me as well) Phil -------------------- ... because the Solar System ain't gonna map itself.

Could b/w shaded relief versions be added to that? I added shaded-relief images from 4 different lighting azimuths. And simple unshaded greyscale 16 bit images (png/tif or similar?) That's very close to the raw IMG files, no? I added grayscale images (PNG, JPG). Erwan |

It'd be great also to know how this community is using the LOLA data, so please reply if you do: Thanks for those, Erwan. I use the RDRs to generate my own surface normal map (see the previous thread). I'm looking into upgrading my network connection, as currently it takes me about a week to download each update! |

Thank you for releasing this early Erwan.
I am using the rdrs to produce datasets, maps and animations. Here is an animation using the LOLA PDS release #5 data. http://www.youtube.com/watch?v=h2GgbcRL0nA |

Its almost certainly bad data. I automatically filter some of the bad data out but it doesn't catch everything.

How are you creating the 3D flybys? JR |

I 'm using the same rendering software I wrote for visualising the Mars HiRISE data. |

UNNECESSARY QUOTING DELETED
I've been looking for a 3D map of the lunar north pole, specifically, a 30km radius centered at 89.55N 30W. I've downloaded the LOLA files and viewed them with LTVT, but that's as far as I've gotten with it. Is your software an adaptation of something that's available online, or is it a custom program?

any dem viewer will work
the lola file is in 16bit singed format the lbl has a off set to use that sets 0.5 Meters increments and in radii in Meters even the old "3DEM" will work check out Virtual Terrain Project http://vterrain.org/ http://vterrain.org/Packages/NonCom/ there is also "Integrated Data Viewer " a java application http://www.unidata.ucar.edu/software/idv/ http://www.unidata.ucar.edu/software/idv/d.../3DSurface.html |

I've tried many of the standalone programs, but I don't know enough about how to manipulate the data to produce images. I'll try the Java program, though.
When I select the LOLA file, I get this error: Reading DEM: D:\My Documents\Space Mining Info\LTVT\LTVT_v0_21_3_1_full_version\LDEM_875N_10M.IMG Data object "D:\My Documents\Space Mining Info\LTVT\LTVT_v0_21_3_1_full_version\LDEM_875N_10M.IMG" not compatible with "dem" data family JR |
