Presentation Transcript

  1. FEATURE: Basics • Convert Feature X in image Y to Line(s),Sample(s) • Load & display ddd image • Graphical interface: click on feature • Convert Line,Sample to Lat,Long (NEW) • Save information in flat file (ASCII text)

  2. FEATURE: Requirements • Pieces required to run FEATURE • GUI computer • IDL • Image (e.g. MSSS ddd format) • ddd file header • TDI timing • DTM (e.g. from PDS) • SPICE • ICY (IDL interface to SPICE toolkit) • Kernels • Duplicate MSSS kernel directory structure locally id 268697607 time 847429225:96 start 0 cross 5056 down 52224 cam ctx mode 0x0 dac 196 offset 187 185 sram_base 0 start_addr 0 exposure 1.87 msec (19) FPA-temp 18.2 C (2398)

  4. FEATURE: Compatibility • Unix, Linux • PC Win • Mac • From requirements slide: • Pieces required to run FEATURE • GUI computer • IDL • Image (e.g. MSSS ddd format) • ddd file header • Contains S/C, instrument, TDI timing • DTM (e.g. from PDS) • SPICE • ICY (IDL interface to SPICE toolkit) • Kernels • Duplicate MSSS kernel directory structure locally

  5. FEATURE: Status • GUI: working • Click Feature X to Line,Sample: working • Save info to text file: working • Line,sample to Lat,Long calcs: working • Integrate Lat,Long calcs: soon

  6. FEATURE: MRO to LROWhat will be needed for FEATURE to work with LRO? • FEATURE is largely mission-independent • Model: each image pixel is a ray in space; ray intersects surface (DTM) • Pixel image timing (from header)  SPICE lookup  ray geometry • Minor mission-specific modifications to FEATURE code are likely • Ideally the LRO ddd headers will be similar to MRO headers • LRO-specific SPICE files: likely from project • Instrument & Frame Kernels (IKs & FKs) • Ideally the project defines the same SPICE variables as MRO • Leapsecond & spacecraft clock kernels (LSKs & SCLKs) • Trajectory & attitude Kernels (SPKs & CKs; ongoing downloads) • “The achilles heel of SPICE is kernel management” • Lunar DTM: convert to same format as MOLA PDS MEGDRs • FEATURE is currently limited to DTMs that fit into a single image as Radius vs Lat,Lon (32 pixel/degree MOLA data) • This limitation may be removed in the future
