This new map provides geologic and structural information on layered sedimentary rocks at a scale comparable to what a field geologist would see on Earth, including a precise illustration of a portion of the “Grand Canyon of Mars,” or Valles Marineris. The map provides new targets for continued scientific investigation of past potentially habitable environments on Mars.

The map is now available for download (Scientific Investigations Map, SIM 3309, PDF and GIS formats).

<![CDATA[Update for ASU THEMIS Day and Night Mosaics]]> Tue, 14 Oct 2014 00:00:00 -0700 ASU has recenty released updates for the THEMIS IR day-time and night-time mosaics. The day-time mosaic is a nice incremental release (from version 11.6 to 12). The night-time mosaic a recommended major release (now at version 14). While the ISIS cube format can be used in GDAL and ArcMap we will make slightly lossy Jpeg2000 versions available as ancillary downloads from the links above.

Note that these mosaics are still only semi-controlled. For the recommended fully controlled THEMIS IR day/night-time quad mosaics by USGS, see this site. This project is still in progress so not all quads are completed.

<![CDATA[New Global Geologic Map of Mars]]> Fri, 18 Jul 2014 00:00:00 -0700 A new global geologic map of Mars – the most thorough representation of the "Red Planet's" surface – has been published by the U.S. Geological Survey. This map provides a framework for continued scientific investigation of Mars as the long-range target for human space exploration. The result is an updated understanding of the geologic history of the surface of Mars – the solar system’s most Earth-like planet and the only other one in our Sun’s “habitable zone.” The new geologic map and GIS database is available for download online.

<![CDATA[THEMIS Geodetically Controlled Mosaics Available from the USGS]]> Tue, 03 Jun 2014 00:00:00 -0700 THEMIS infrared geodetically controlled mosaics, updated spacecraft pointing and orientation information (i.e., preliminary smithed SPICE kernels), and supporting documentation are available for download and public use from the United States Geological Survey (USGS) Astrogeology Science Center.  Nine daytime infrared and eight nighttime infrared mosaics are currently available, with additional mosaics being released each January and July until a global product is completed.  These mosaics are tied to a known coordinate system (USGS Viking Orbiter Mars Digital Image Model 2.1), spatially adjusted to align feature boundaries, and orthoprojected at 100 m/pixel scale.  This process results in sub-pixel registration between images and the daytime IR and nighttime IR mosaics to be well-registered to one another. These products enhance our knowledge (e.g., position, precision, and accuracy) of image placement and the location of small-scale surface features, and will benefit the current and future orbital acquisition of data, the planning of spacecraft and surface operations, and allows for easier and improved intercomparison of all Mars data sets.

 Please see the following website for product download and additional documentation: http://astrogeology.usgs.gov/maps/mars-themis-controlled-mosaics-and-preliminary-smithed-kernels

<![CDATA[Note for NASA Proposers, Geologic Mapping]]> Fri, 21 Feb 2014 00:00:00 -0700 Proposed geologic mapping or topical science investigations of any planetary or satellite surface that are intended to result in the publication of a Scientific Investigations Map (SIM) by the U.S. Geological Survey (USGS) should check the relevant box on the proposal Cover Page and clearly indicate this intention in the Proposal Summary, as well as in the text of the proposal. Investigators who choose to produce a geologic map as a USGS product will be required to follow current guidelines for the production and submission of digital products, including the generation of maps that are compatible with Geographic Information System (GIS) software packages for review, edit, and publication. To support this requirement, the USGS will provide a GIS project that contains the projected, geographically rectified, and scaled mapping base or mosaic as well as other relevant global- or regional-scale data sets (if available and needed). Investigators selected to publish USGS geologic maps will be expected to (1) provide peer reviews for two geologic maps generated by other planetary mappers, and (2) attend the annual Planetary Geologic Mappers Meeting to present map status to the mapping community and receive updates on current guidelines. Proposers are encouraged to contact James Skinner at USGS (jskinner@usgs.gov) in order to obtain further information pertaining to the production of USGS geologic maps (e.g., map bases, scales, extents, formats, guidelines), or visit http://planetarymapping.wr.usgs.gov/Page/view/FAQ

<![CDATA[Contour merging and attribution tools for ArcMap 10.1]]> Fri, 13 Sep 2013 00:00:00 -0700 Ever need to clean and attribute scanned contours? Once the scan has been converted to vector lines (e.g. using ArcScan or GDAL), you may find these two ArcMap 10.1 add-ins helpful for merging and semi-automatically attributing the contour lines. The first tool, Iterative Self Select Intersected, helps to merge lines along the contour path which helps with contour attribution. The second tool, Contour Line Attribution Tool, is designed to allow the user to draw a line (generally perpendicular) that intersects one or more unattributed contours. The user then sets the start elevation value and the interval at which the elevation contours should increment. The lines are then attributed, incrementing the elevation value, as they are intersected. For both tools, the Python code is freely available in the download and can be modified in any way. Just rename the file to a .zip and unzip.

<![CDATA[Magellan SAR and synthetic stereo mosaics by quadrangle]]> Mon, 09 Sep 2013 00:00:00 -0700 The Magellan SAR and Synthetic Stereo Mosaics were created back in 2002 by Vicki Hansen and Duncan Young at the University of Minnesota, Duluth. These are just visual Jpegs and currently do not have geospatial headers for mapping applications. Description: synthetic aperture radar (SAR, cycles 1, 2, or 3) and altimetry data from the NASA Magellan mission (1991 – 1994) can be digitally combined to create synthetic stereo images. Because SAR and altimetry cycles image ~98% of the planet (Kirk et al., 1992), synthetic stereo can be created globally except at the poles. The stereo pairs are viewed as color (red-blue) anaglyphs. Red color projects the combined SAR images from both cycles, and the blue color projects the distorted image to produce a red-blue anaglyph.  You can currently view and download the images from here: ftp://pdsimage2.wr.usgs.gov/pub/pigpen/venus/MagellanSARimages_SyntheticStereo/

<![CDATA[Mapper Tip: ArcMap 10.1 Copy and Paste Symbology]]> Mon, 01 Jul 2013 00:00:00 -0700 In ArcMap, have you ever needed to set the black edge around a ton of images to transparent? We have just released a new toolbox which might help. This new tool can copy the symbology from one defined layer and paste it to one or more other layers loaded in the table of contents (TOC). The ArcMap 10.1 Python toolbox contains tools to work with rasters (images) and feature layers.

The toolbox can be download from: http://www.arcgis.com/home/item.html?id=b282ba43695c401aa75d32336eaca82f

For setting the same color-scale for many images (e.g. DEMs), then I recommend loading them into a Mosaic Datatype. This allows all images in the Mosaic to have one symbology mapping. See: Raster Riser for a Mosaic tutorial: http://astrogeology.usgs.gov/facilities/mrctr/gis-tools

<![CDATA[New website released for the Planetary Geologic Mapping Program]]> Wed, 17 Apr 2013 00:00:00 -0700 Astrogeology's Planetary Geologic Mapping Program is pleased to announce a renovated website. The new site is built to help the planetary community locate completed geologic maps, track maps currently in progress, and find regions which are not yet funded to be mapped. The original website will be available until the new site is fully complete, but will not be updated.]]> <![CDATA[Renovated lunar GIS geologic files released]]> Tue, 26 Mar 2013 00:00:00 -0700 The digital 1:5,000,000-scale lunar geologic map series (I-703, I-948, I-1034, I-1047, I-1062, and I-1162) are now released and available for download. These renovated GIS databases utilized new topographic data and image mosaics to spatially adjust the contacts, structures, geologic and surface units, and map boundaries to the current Lunar Reconnaissance Orbiter (LRO) Lunar Orbiter Laser Altimeter (LOLA) control networks. While these new maps do not represent a re-interpretation of the geologic history presented in the original maps, the locations of some of the units and contacts have been redrawn to better conform to the basemap resolutions afforded by recent data acquisitions. For more detailed information and a quick view, see the abstract and poster given at 44th LPSC in 2013.]]>
