    February 3, 2016
    The Image Grabber utility program has been upgraded to Version 1.8.2. This minor revision permits retrieving files from internet sites in which there is an embedded comma in the URL (for further details, see "Image Grabber Directions.txt" in the program download package).

    December 18, 2012
    The basic dot files for Mercury, Venus and Mars have been updated to incorporate changes to the IAU nomenclature and control networks through December 15, 2012. The basic and specialized lunar dot files have also been updated to reflect minor changes to the "origin" field for a few features.

    Links has been added to the end of the Additional Textures page to several LTVT-compatible global lunar texture files assembled by Jean-Charles Bouget from various Lunar Reconnaissance Orbiter Camera - Wide Angle Camera data sets.

    June 16, 2012
    A new version of the basic lunar dot file for the IAU-named features on the Moon is available on the LTVT download page. It incorporates the new LOLA-based lunar positions and diameters announced by the IAU on June 4, 2010, as well as new minor crater names (one introduced on March 29, 2012 and twelve on June 15, 2012). The specialized lunar dot files have also been updated as well as those for Mercury and Mars.

    Here is the 16 points per degree LDEM_16.IMG from 16 Mar 2010 of LOLA data transformed to a JPEG grayscale image, which can be used as an LTVT texture. The intensities of "0" and "256" corresponding to the extremes of the altitude range given in the DEM info. The map has been adjusted so that it spans the LTVT default range -180° to +180° in longitude and +90° to -90° in latitude (the original spans 0° to 360° in longitude, which, in LTVT, can be used only as "Texture 3"):

    French amateur Jean-Charles Bouget has assembled LTVT-compatible global lunar texture files from several Lunar Reconnaissance Orbiter Camera datasets. Although they are too large to upload to the LTVT Wiki, Jean-Charles has kindly made them available on his Dropbox site.

    With both sites it is wise to check that the final image size corresponds to what you requested. For example, at 10 pixels per degree the image should be 3600 pixels wide (360°) and 1800 pixels tall (180°). Occasionally the downloads terminate prematurely giving an erroneous display size, and in those instances features will not display in their proper positions.
    LTVT can also display the texture files that come with many other Moon mapping applications, such as the Virtual Moon Atlas, and one of the texture buttons can be set to display simple cylindrical reference maps covering less than the whole Moon (such as the USGS Warped Clementine tiles). See the program help file for further information.
