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
