ISIS Support for JAXA Missions Hayabusa Mission Goal: Restore data from the Hayabusa spacecraft (NIRS spectrometer and Asteroid Multi-Band Imaging Camera or AMICA) on the Planetary Data System (PDS) Small Bodies Node.
Support: NASA Planetary Mission Data Analysis Program. PI: Vishnu Reddy (LPL/UA) and Co-Is: Lucille Le Corre (PSI), Kris Becker (USGS), Jianyang Li (PSI), and Collaborator: Bob Gaskell (PSI) Results: Calibrated AMICA color images NIRS spectra will be available on the PDS by end of 2017

ISIS Support for JAXA Missions Hayabusa-II Mission Goal: Generate higher level data products (color maps, shape model and SPICE kernels) in near-real time for sample site selection.
Support: NASA Hayabusa II Participating Scientist Program. PI: Lucille Le Corre (PSI), Co-Is: Kris Becker (USGS), Jianyang Li (PSI), and Collaborator: Bob Gaskell (PSI) Leverage existing tools in ISIS from Hayabusa mission including camera and spectrometer calibration pipelines

ISIS3 Update
• ISIS 3.5.0 is scheduled for release on Jan 25 • Major change to third party libraries used by ISIS.
• No mission should put this into production until it has been thoroughly tested in their environment.
• The supported platforms are: • RHEL 7 • Ubuntu 14.4 LTS • Debian 8 • Fedora 21 • Max OS 10.11 • (Windows needs VMWare to run ISIS3)
Mapping Improvements
• pixel2map now has options to map the full field-of-view (FOV)
• Prior behavior was to map the instantaneous FOV (IFOV) at the center of the observation exposure time
• Users can now specify the number of IFOVs evenly spaced within the observation exposure duration for each pixel
• Pixel IFOVs are combined (via GIS unions) and filled with the pixel DN value and mapped on the body using any associated digital elevation model (DEM)
• Hayabusa 1 NIRS camera model developed • The NIRS is a spot spectrometer • pixel2map improvements provides better mapping support for
these types of instruments
New Applications and Features • Developed a new projection called the UpturnedEllipsoidTransverseAzimuthal
• Useful for very oblate bodies
• cnetthinner determines best control point coverage in each image • Used for dense control networks • Thins (removes) points in images using maximal suppression algorithm that computes the
widest dispersed points selecting the user specified minimum points/image
• sumspice improvements • Applies Gaskell control directly to ISIS images resulting from his stereo photogrammetric
DEM production processing techniques • Added generalization properties to support wider variety of instruments and timing
situations
• findfeatures updated to use OpenCV 3 • Previously used OpenCV 2 library • Version 3 provides new feature detectors and extractors • Large effort to provide ability to utilize entire feature matching algorithms as
interchangeable combinations of detector, extractor and matcher
Shape Models Supported
• Triaxle Ellipsoids • Digital Elevation Models (DEMs)
• Planetary Radius
• Digital Shape Kernel (DSKs) • Tessellated plate model • Using the NAIF DSK library
ISIS3 allows use to either use a default shape model or define your own.

USGS Resource Assessment
USGS MISSION • The “Organic Act” of 1879
established the USGS with a few specific obligations, one of which was “the classification of public lands and examination of the geologic structure, mineral resources, and products…”
• In 1962, Congress extended those examinations to “beyond the borders of the United States.”
• In 2015, USGS management recognized that this phrase extends the USGS legal obligation to space.
The USGS Resource Assessment Methodology: • descriptive model. • grade-tonnage model • deposit-density model
Example Results have been submitted as an LPSC abstract • Kestay et al., 2017
