- SciSQL does not support what we need for searching images
- concerned about indexing (finding fast whether polygons overlap)
- if images of different size, need to pick some coarse level of htm, that is suboptimal
- can store multiple htm levels
- likely need special index, eg 3-d R-tree
- Talk to mysql GIS experts at: http://www.percona.com/live/mysql-conference-2015/
- in Fermi, dealing with "events" that are point, we deal with areas
- science question: what do we need to support in terms of searching / selecting images. E.g., point in image enough? Polygons overlapping images. Jacek will ask Mario Juric. Via JIRA ticket.
- Serge will update JIRA ticket: add notes what to test
Raw images

- SUI can always request the image as FITS
- Returned data?
- Raw pixel plus metadata we obtained from obs control system and telescope control system (which will include "where telescope was pointing" – approx WCS)
- few years later, when we have precise WCS, we might want to return that with image. But might want to call it differently ("augmented raw image")
- Size units?
- typically amplifier level
- ok to request smaller than amplifier (although it is usually not useful)
- There is no such thing as CCD raw image. No plans to do stitching raw images
- Typical uses of raw images? What metadata should go with raw data? Xiuqin will ask Mario Juric. Via JIRA ticket
