Dan Slayback Fritz Pollicelli Edward Masuoka
Karen Michael Diane Davies Gang Ye Gregory Ederer | Progress on Phase 1: Granule Module |
- Gang Ye to send Dan recommendations for logging code
- Edward Masuoka to check with SAs re: python version. He will get back to Dan if the latest (ver 3.5) is not acceptable.
- Fritz to follow up on other flood portals / viewers to get a sense of what will be done and the likely timeline,

Karen Michael Diane Davies Gang Ye Fritz Pollicelli Dan Slayback | - Dan: Tests show that the GDAL prototype is as efficient as ENVI / IDL
- Dan to finalize code to generate the granule level water detection data (intermediate file). Estimated time frame 1 month
- Next steps:
- Dan to finish code for the final daily products (2,3,14 day products). He may need input from Gregory Ederer/ others to make this code as efficient possible - approximately another month taking us to mid September.
- After that we need to consider final formats for end users
- Fritz sent Dan some feedback from end users. Diane to create short set of questions which will go to a broader audience.
|
Action items- @Dan Slayback to report back to Edward Masuoka that he won't need the additional ENVI license
- @Dan Slayback to finalize code to generate the granule level water detection data and deliver it to Gang Ye
- Gang Ye to send Dan sample ESDT file names
- Diane Davies to contact additional users, in collaboration with Fritz, to draft user requirements doc

Diane Davies Gang Ye Edward Masuoka @Frederick Pollicelli @Dan Slayback | Phase 1: Granule Module | - Flood product is currently run using IDL and ENVI and it uses 10 x 10 degree tiles (MOD09, MOD35 and MOD06) as input and generates MODIS Water Detection (MWD) and MODIS Cloud and Shadow (MCS) data files in same format.
- Dan will modify code to use granule data as input so the MWD and MCS can be processed as soon as the data are available
- Dan will assess whether the to use IDL / ENVI or GDAL / Geo Tools
- no licenses are required for the GDAL option but if it is going to take longer, Ed is willing to buy another ENVI license
- Dan to provide feedback the week of 10th July
- Dan will then deliver his code to Gang (by 17 July)
- Gang and LAADs team will take the code and wrap it in to PGEs for NRT processing
|
Phase 2: Mapping and Compositing module This module creates products on a global 250m grid | - Who: PI staff can prototype, but TBD who will build and operate this component (LANCE or PI staff). Schedule: Start after stage 1 complete.
Estimated completion: TBD |
Phase 3: Post processing module for distribution | - Generate final distribution format files (geotiff, shapefile, KMZ, graphics) from the master product and publish to web, ftp, GIBS (if possible), etc.
- Diane to review information Fritz collected from user survey and to develop additional questions (as appropriate) and contact users to develop end user requirements.

Next Meeting: | 17 July 2017 |
Action items
- @Dan Slayback: Test granule approach with ENVI / IDL
- @Dan Slayback: Prototype GDAL to see if it is as efficient as ENVI / IDL option & report back to Edward Masuoka, Gang Ye, Fritz, Gregory Ederer and Diane Davies the week of 10 July
- Edward Masuoka will purchase additional ENVI license if Dan thinks it will be more efficient to run code using ENVI
- @Dan Slayback to provide granule input code to Gang Ye / Gregory Ederer for PGE integration
- Diane Davies to meet with @Fritz Pollicelli next week to discuss end user requirements
- Diane Davies to contact additional users and draft user requirements doc
