• L1/L2 - Trajectory Subsetter - SMAP special casecase - Gridded outputs
  • Enable in existing code base for Cloud deployment
  • Gridded outputs to .h5 (Cropped grid, Revive un-merged branch?  Not-GeoTIFF as is current)
  • GeoTIFF formatter (COG, HGA) - chaining
  • Reprojection special case? (HGA?, chaining)
    
    
• L1/L2 - Trajectory Subsetter + general chaining for formats (ICESat-2, SMAP, other?) √
  • Projection - use Swath-Projector (minor updates likely)
    
    • (Potential use cases for Oblique Equal-Area, Oblique Mercator, or Oblique EquiDistance projections)
    • (Not an existing on-prem feature)
  • Reformat: Vector Data: Shapefile, KML, NetCDF, multi-file: ASCII
    - as micro services, lifted mostly from on-prem implementations (or port/rewrite)
    • (Note size constraints, e.g., ICESat-2 files)
    • NetCDF: CF, metadata upgrade from .h5 
    • ShapeFile, KML format output (.shp, .kml, .kmz) 
    • ASCII format output? - rewrite to Python, chaining - single file per variable
      • CSV
        • Choice of delimiters? (Comma, tab)
        • “Row of vars” per time-stamp? (see Tabular ASCII)
        • “Time, Name, Value” format
          or “Time, Value” per variable (name)?
        • GDAL standard?
      • “Tabular-ASCII” - lifted from on-prem, or rewritten to Python
        • Textual layout
        • “Row of vars” per time-stamp
        • Blocked per group and/or frequency (count)
      • OPeNDAP / GDAL (HGA): various ASCII format choices ?
        
        
• L3/L4 - HOSS + chaining (ICESat-2, SMAP other?) √ (some reconfig, perhaps tweaks to code?)
  (Note will be .nc4 output not originally scoped .h5, but hopefully not significant)
  • • ICESat-2 has some notorious quirkiness - Lower-Left orientation, Edge-Aligned dimension scales
    • Possible support for missing dimension-scales - use CF-ish config entry for grid-parameters (SMAP)
      - see: GeoTagging for a Geo-Located Grid Array
  • Reprojection - TBD (I suspect not HGA, rather PyResample based, Data Reprojection Wizard)
  • Reformat - GeoTIFF/COG (HGA?), other standard Cloud formats, Zarr
