Coordinates of Named Features on Io Updated to Voyager/Galileo SSI

08/20/2012

In 2012, the coordinates of the named features in the Io portion of the International Astronomical Union Gazetteer of Planetary Nomenclature were updated from values from historical sources to values in the Voyager/Galileo SSI control network. The purpose of this work was to facilitate the identification of named features on Io. Dots representing the center coordinates of named features should fall in the centers of the features when displayed on any map product based on the Voyager/Galileo SSI reference frame. The extents and sizes of the named features were also updated; these data are approximate and are intended solely to give the user sufficient information to identify named features and their rough extents.

This new set of coordinates was derived using ArcMap version 10.0 and the 2011 Geologic Map of Io by David Williams et al. Vectors describing feature extents are based on the geologic contacts shown on this map. We are also grateful for help and advice provided by Dr. Rosaly Lopes and Dr. Jani Radebaugh.

The Io portion of the Gazetteer of Planetary Nomenclature web site now defaults to showing feature coordinates in the frame of the Voyager/Galileo SSI control network. The original coordinates (from unknown sources) are still retained in the gazetteer and can be viewed by selecting the desired coordinate set from a dropdown menu on the feature pages. The "Unknown" coordinates are now considered archival and will not be updated with new names or changes to approved names.

Martian Crater Coordinates now in MDIM 2.1

Wed, 17 Nov 2010 10:11 MST

In October 2010, the coordinates of the named craters in the Martian portion of the nomenclature database were updated from values from the Mars Digital Image Mosaic (MDIM) 2.0 control network to values in the MDIM 2.1 control network. The purpose of this work is to facilitate the identification of named Martian craters. The locations of the craters in the KML and shapefiles will correspond to the crater locations on any map product that was created using the same MDIM 2.1 control network.

The extents and sizes of the named craters were also updated; these data are approximate and are intended solely to give the user sufficient information to identify the craters and their rough extents. A link to a more precise global crater database by Stuart Robbins will be provided when available.

This new set of coordinates was derived using ArcMap version 9.3.1 and the Mars Digial Image Mosaic 2.1. Some small craters are not resolved well in the MDIM 2.1 image; for these cases, feature coordinates were derived from the Thermal Emission Imaging System (THEMIS) Day IR 100m global mosaic. We would like to thank Stuart Robbins (University of Colorado, Boulder) for sharing a portion of his forthcoming global crater database, which provided a valuable and time-saving starting point for this work.

The Martian portion of the Gazetteer of Planetary Nomenclature now defaults to a new set of coordinates; the craters match MDIM 2.1, and the non-crater features are still in the MDIM 2.0 control network. The craters were updated first because they are the smallest features and therefore the mismatch between MDIM 2.0 and MDIM 2.1 was most obvious. Named non-crater features will be updated at a later date. The data set that contains all of the features in the MDIM 2.0 control network is still retained in the gazetteer, but is now considered archival and will not be updated with new names or changes to approved names.

Coordinates of Named Lunar Features Now Available in LOLA Reference Frame

06/04/2012

In 2012, coordinates of the named features in the lunar portion of the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN) Gazetteer of Planetary Nomenclature were updated. Previous coordinates were based on maps using the Unified Lunar Control Network (ULCN) 2005 coordinate reference frame. The new coordinates are derived from maps made in the Lunar Reconnaissance Orbiter (LRO) Lunar Orbiter Laser Altimeter (LOLA) coordinate reference frame. These reference frames are referred to the mean Earth/polar axis reference coordinate system for the Moon. The updated coordinates will facilitate the identification of named lunar features on images derived from LOLA topography. Dots representing the center coordinates of named features should fall in the centers of the features when displayed on any map product based on the LOLA reference frame.

The extents and sizes of named features were also updated; these data are approximate and are intended solely to give the user sufficient information to identify named features and their rough extents. A link to a more precise lunar crater database (now in preparation) by Dr. Nadine Barlow will be provided when available.

This new set of coordinates was derived using ArcMap version 10.0 as a display tool, a lunar hillshade image based on LOLA topography (LDEM_128.jp2, 128 pixels/degree or 237 m/pixel, released December 2011, http://pds-geosciences.wustl.edu/missions/lro/lola.htm), and a LRO Wide Angle Camera (WAC) image mosaic (released November 2011, http://wms.lroc.asu.edu/lroc/global_product/100_mpp_global_bw). Feature boundaries were determined using both images, but the features were aligned to the LOLA hillshade image where there were slight discrepancies.

The lunar portion of the Gazetteer of Planetary Nomenclature web site now displays feature coordinates in the LOLA reference frame. The original coordinates (from unknown sources) and the ULCN 2005 coordinates are retained in the gazetteer and can be viewed by gazetteer users by selecting the desired coordinate set from a dropdown menu on the feature pages. The “Unknown” and ULCN 2005 coordinates are now considered archival and will not be updated with new names or changes to approved names.

No More Provisional Names

09/06/2006

There has been an important change in the approval process for planetary feature names; the designation of "provisional nomenclature" is no longer used. As soon as the IAU Working Group for Planetary System Nomenclature (WGPSN) has successfully reviewed a name, it is considered approved and can be used in publications. Immediately after WGPSN approval, names are entered into the Gazetteer of Planetary Nomenclature. Any objections to these names based on significant, substantive problems must be forwarded in writing or email to the IAU Division III president within three months of the names being published in the gazetteer.

This new policy will allow for much more efficient use of planetary feature names for the scientific community, and it will streamline and simplify the use of planetary feature names in the publication process.

Mercury Feature Coordinates Updated to MESSENGER

Mon, 07 Mar 2011 09:43 MST

In late 2010, the coordinates of the named features in the Mercury portion of the nomenclature database were updated from values from historical sources to values in the preliminary MESSENGER control network. The purpose of this work was to facilitate the identification of named features on Mercury. Dots representing the coordinates of the centers of named features will fall in the centers of the features when displayed on any map product that was created using the same control network.

This new set of coordinates was derived using ArcMap version 9.3.1 and the global map of Mercury. Because MESSENGER does not yet have global coverage of Mercury, Mariner 10 data were used to fill in areas where MESSENGER has not yet collected image data. In order for the two data sets to align, the preliminary MESSENGER control network was tied to the Mariner 10 map using several ground truth points.

The Mercury portion of the Gazetteer of Planetary Nomenclature web site now defaults to showing feature coordinates in the frame of the preliminary MESSENGER control network. The original ‘unknown’ source coordinates are still retained in the gazetteer, but this data set is now considered archival and will not be updated with new names or changes to approved names.

Martian Crater Coordinates now in MDIM 2.1

Mars Feature Coordinates Updated to MDIM 2.1

Thu, 11 Aug 2011 14:37 MST

The Mars portion of the Gazetteer of Planetary Nomenclature now defaults to a new set of coordinates; all of the Martian features now match the Mars Digital Image Mosaic (MDIM) 2.1 control network.

In late 2010, the coordinates of the named craters in the Martian portion of the nomenclature database were updated from values from the MDIM 2.0 control network to values in the MDIM 2.1 control network. In the spring of 2011, the remaining Martian features (i.e., all the named features that are not craters) were also updated to MDIM 2.1. Since the MDIM 2.1 network was tied to local Digital Elevation Models (DEMs) generated from Mars Orbiter Laser Altimeter (MOLA) data, this implies the features now match MOLA data products and other products in that reference frame. The GIS download that contains all of the features in the MDIM 2.0 control network is still retained in the gazetteer, but is now considered archival and will not be updated with new names or changes to approved names.

The extents and sizes of the named features were also updated, and vectors describing feature boundaries were drawn; these data are approximate and are intended solely to give the user sufficient information to identify named features and their rough extents.

This work was accomplished using ArcMap version 9.3.1 and theMars Digital Image Mosaic 2.1. Some features are not resolved well in the 2.1 mosaic; for these cases, feature coordinates were derived from the Thermal Emission Imaging System (THEMIS) Day IR 100m global mosaic. We would like to thank Stuart Robbins (University of Colorado, Boulder) for sharing a portion of his global crater database, which provided a valuable and time-saving starting point for the crater portion of this work.

Lunar Coordinates Now Available in ULCN

Mon, 18 Oct 2010 12:27 MST

In 2010, the coordinates of the named features in the lunar portion of the nomenclature database were updated from values from historical sources to values in the coordinate frame of the Unified Lunar Control Network 2005 (ULCN 2005, see http://pubs.usgs.gov/of/2006/1367/). The purpose of this work was to facilitate the identification of named lunar features. Dots representing the coordinates of the centers of named features will fall in the centers of the features when displayed on any map product that was created using the same ULCN 2005 control network.

The extents and sizes of the named features were also updated; these data are approximate and are intended solely to give the user sufficient information to identify named features and their rough extents. A link to a more precise crater database (now in preparation) by Dr. Nadine Barlow will be provided when available.

This new set of coordinates was derived using ArcMap version 9.3.1 and the Lunar Orbiter Digital Photographic Mosaic (http://www.mapaplanet.org/explorer/help/data_set.html#moon_lo). Where data gaps exist in the Lunar Orbiter image, the features were aligned with the USGS airbrushed shaded relief mosaic, which was warped to the same control network as the Lunar Orbiter mosaic (ULCN 2005) (see http://www.lpi.usra.edu/meetings/lpsc2008/pdf/2245.pdf).

The lunar portion of the Gazetteer of Planetary Nomenclature web site now defaults to showing feature coordinates in the frame of the ULCN 2005 control network. The original ‘unknown’ source coordinates are still retained in the gazetteer, but this data set is now considered archival and will not be updated with new names or changes to approved names.
