Summary
A number of proposed changes to data fusion were mentioned and a request for requirements and ideas was made.
- Yiwei was curious about the speed and memory efficiency of the new design.
- tjohnson requested that it be possible to specify offset and scale for layers which do not have georeferencing or tie point information.
Decisions
- Add a requirement to data fusion to maintain or exceed the current memory and speed performance
- Add a requirement to data fusion to allow fusing of data without georeferencing information or tie points using offset and scale.

2010-07-26T11:00:10 <tclarke> please review and make any necessary corrections
2010-07-26T11:00:12 <tclarke> we'll start with SoC updates
2010-07-26T11:00:37 <tclarke> both students continue to make progress...I won't go into details, if anyone would like to discuss andything in particular, I'll leave the floor open for a moment
2010-07-26T11:01:02 <tclarke> ok, if there's nothing more to discuss, we'll move on
2010-07-26T11:03:06 <tclarke> as part of 4.5.0 I'm planning a number of improvements to data fusion and I'd like to take a moment to solicit some ideas and requirements
2010-07-26T11:03:39 <tclarke> my current plan is to streamline to procedure so that many of the fusion and linking processes occur in the Session Explorer instead of in a separate GUI
2010-07-26T11:03:51 <tclarke> users will be able to create new layers for existing raster elements via drag and drop and context menus
2010-07-26T11:04:06 <tclarke> also, the user will be able to change layer stretch and offset from the GUI
2010-07-26T11:04:24 <tclarke> the data fusion plug-in will primarily consist of an algorithm to perform the warping needed when the datasets do not have the same projection and GSD
2010-07-26T11:04:43 <tclarke> I also plan on implementing OPTICKS-530 which creates porthole and swiper tools in addition to the transparency adjustment
2010-07-26T11:06:22 <tclarke> that's a brief description of the planned changes, are there any ideas or requirements I should be aware of?
2010-07-26T11:07:07 <Yiwei> How about the speed/memory efficiency of this new scheme?
2010-07-26T11:08:31 <tjohnson> If the elements lack geocoords, the user should be able to set the offset and scaling of the layers.
2010-07-26T11:08:36 <tclarke> the warp algorithm will be essentially unchanged so it will have the same execution speed and the option to trade speed for memory efficiency
2010-07-26T11:08:49 <tclarke> tjohnson: that is planned...I also plan to use tiepoints for the manual alignment step so if there are no geocoords, you can still perform warping
2010-07-26T11:08:59 <tclarke> I'll likely implement scale and offset via mouse modes which move and stretch the top layer
2010-07-26T11:09:11 <tclarke> I'll ensure those requirements are in the feature analysis
2010-07-26T11:09:25 <tclarke> ok, if there are no others, we'll move on to open questions
2010-07-26T11:09:29 <tclarke> first, the release schedule:
2010-07-26T11:09:45 <tclarke> an issue (OPTICKS-962) has been reported which effects a number of 4.3.3 deployment
2010-07-26T11:09:52 <tclarke> this is a major issue for those deployments so it has necessitated a v4.3.4 release
2010-07-26T11:09:57 <tclarke> this release will only contain a fix for OPTICKS-962
2010-07-26T11:10:08 <tclarke> the exact schedule has yet to be determined but the rollup will take place sometime in the next couple of weeks
2010-07-26T11:10:18 <tclarke> also, this issue and another issue will necessitate an 4.4.0rc2
2010-07-26T11:12:37 <tclarke> as of now, the 4.4.0 release is still on schedule as there is some time set aside for the rc2 already
2010-07-26T11:12:48 <tclarke> more details about the exact release dates will be made available when they have been established
2010-07-26T11:12:52 <tclarke> anything else on the release schedule?
2010-07-26T11:12:56 <tclarke> if not, I'll leave the meeting open for other questiosn
2010-07-26T11:13:35 <tclarke> ok then...the meeting is over
2010-07-26T11:14:50 <tclarke> watch the email list for notes and the agenda for next time
