Can one turn on and off the "reload upon reprojection status of a

I don't see a checkbox there:
It's not in the Display Properties (but could be). In discussions with SSEC,
clicking OK/Apply on the Properties causes lots more things to happen than just
changing a property. So, we put it under the View menu.
But there it applies to all displays equally.
If I created a PR display, can I convert it to a fixed display that does NOT
reread?
Yes. Go to the View->Use Progressive Disclosure menu of the display
control and uncheck it.
Or do I have to go create another, identical display, but this time without
using the
convenience of "Match Display Region"?
See above.
It would only serve for a whole new use style: always navigate the map
before loading anything.
Who does that? No current user.
That's the default behavior in NMAP2 - subset and load data into the projection
of the currently displayed region.
I could get used to it.
I think that's what Jim and Kevin (and maybe others) were requesting.
This eliminates the need to do manual subsetting of different datasets
loaded into the same view.
Here's my use case. I make a bundle over Colorado of satellite, radar,
observations and model data. I use that for looking at the weather over my
area on a daily basis. On a particular day, there is some interesting weather
(e.g. a Cat 5 hurricane hitting Miami). I want to look at the weather over
Florida using the same displays I have over boulder. I could load in the
boulder bundle, and then change the projection to florida and that would work,
but I'd be loading data twice.
You can reproject/move the bundle before the initial loading has completed,
right?
Or is that hazardous?
There is no support for this currently. I've got it partially working
in my development code, but only for grids. There are some caveats to
this, however which I'll detail at a later date.
So - to avoid the auto-reload, do I need to uncheck the box during
display creation?
(TOO HARD TO REMEMBER EVERY TIME)
Or can I just need to create a display without using the Match Display
Region?
That's what I would do. Then it will always be at the resolution you picked
when you loaded it in.
Which one?
To repeat the question:
Does the user have to uncheck the PR to get a fixed display?
Right now, you have two options to turn off PR for a display:
- turn it off for the view (uncheck Projections->Use Progressive
Disclosure) before you create the display.
- Create the display and then uncheck the display control's View->Use
Progressive Disclosure menu.
Or will any display created without Match Display Region be of fixed area?
The default for all displays is whatever is set for the view they are
created in.
The global preference sets the default on any view created. Each display gets
it's preference from the view it is being loaded into. If you turn off PR
before you create the displays, they will not be reloaded if you change
projections or use the RBB.
You seem to be saying I have to "turn off" PR under Projections,
in order to get a non-reloading display -- even if I don't use the
Match functionality. Is that right?
Yes to make that the default behavior for all displays created in the
view, or turn it off afterwards for each individual view.
Thanks for much clarification!
Does that make it clearer?
