Next Plans

• Get admin areas for affected areas of TC Ompong - AOI
• Grab nightlights data for 20180912 (Date of entry of “Mangkhut” into par)
  • grab ’*.rade9.co.json’ for all data in s3://globalnightlight/npp_201809
  • parse ’*.rade9.co.json’ and convert to geojson
  • find files intersecting affected areas of TC Ompong -
  • fetch files ’*.rade9.co.tif’ for files intersecting AOI
  • fetch files ’*.vflag.co.tif’ to mask for no data/cloud cover.
  • check if there is enough data for analysis – no data < 5 percent
• Repeat process for 20180916 (Date of exit of “Mankhut” from par)
• Compare variance of nightlights over AOI
