2 Asteroid Resource Assessment Geologic Mapping

3 Cradle-to-Grave and Beyond Mission Support PDS Imaging Node PILOT RPIF Data Archival Processing Analysis ISIS3 SOCET SET Adds Value to Mission Data Cartography Calibration Data Fusion Software and the Data available and usable post-mission PDS Annex ISIS3 PDS Annex accepts higher-order products Geologic Maps

4 USGS Small Body Mission Support: Integrated Software for Imagers and Spectrometers Current Missions OSIRIS-Rex OCAMS Hayabasa-2 Optical Navigation Cameras NIRS3 New Horizons LORRI MVIC LEISA Dawn FC2 VIR Past Missions Rosetta (Steins & Lutetia) OSIRIS VIRTIS Hayabusa-1 NIRS AMICA NEAR/Shoemaker Voyager/Galileo

5 ISIS3 Needs: Raw Image Camera Model Telemetry (SPICE) Shape Models S/C Images Ingression S/W SPICE/Ephemeris Camera Model Shape Model/Coordinate System Map projected Images

6 How is ISIS3 Funded? NASA Interagency Agreement (IAA) ISIS3 Maintenance & General Support Active US Missions Cover New Camera Models & Ingestion S/W New Shape Models Foreign Missions Covered By Participating Scientists PMDAP (Legacy Program) Archived Missions/Data PDART PMDAP/DDAP/RDAP IAA

7 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 Raw Smear Calibrated Smear-removed Slide provided by Vishnu Reddy, Univ. of Ariz.

8 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 Slide provided by Vishnu Reddy, Univ. of Ariz.

9 ISIS3 Update ISIS 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 (Windows needs VMWare to run ISIS3)

10 Mapping Improvements pixel2map now has options to map the full field-ofview (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

11 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

12 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. Credit: Images are from NAIF: 27_shape_model_preview

13 PILOT: Phobos, Deimos, Vesta

14 Nomenclature: Current Small Body Focus Ceres Pluto System

15 Regional Planetary Image Facility Phobos

16 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
