[mapserver-users] Color temperature control (night-time viewing of maps)

[Basques, Bob (CI-StPaul)]

David,

Night vision is the bigger problem.  Many users will be driving on dispatch tickets, etc.  Don't want to introduce a fatiguing function to the night drivers.

This is purely a demo mode of display for now.  The idea being to put something out for feedback from the end users.

Bob,

Are you thinking of preserving night vision or pumping up the blue to keep people more awake?

All,

So, I've been reading up on nighttime colors for electronic display(s).  I was wondering if anyone has any pointers on information about applying color temperature corrections to displays for nighttime viewing.  I'm in need of providing this functionality to some night crew workers.

My first thought was to apply some sort of RGB algorithm to the mapfile color settings.  Then I thought maybe a middleware  processor routine (between MapServer and the browser) might be a better approach, or possibly using something in the browser . . .

I'm only looking at setting up distinct color settings at the moment.  Maybe 3-5 ranges to start with.  I do know that some Mac hardware has some display monitoring for color temperature.  I would prefer to do something that could apply globally however.

Maybe there are Browser functions that can be applied to the problem (I haven't found anything specific there yet though.

Thanks

Bobb
