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

Re: [mapserver-users] Color temperature control (night-time viewing of maps)
Hi Stephen, Yes, that looks like the correct route for this, time/location settings, at least to make something work globally. The display is for a mapping interface that will most likely be location aware. I've found a couple of references to some LIBs for finding terminator, and I think a temperature curve could be defined based on optimum settings from day/dusk/night views to make the map readable for all (natural) lighting conditions. At least that's a place to start.

I have even worked out how I can make the changes to a mapfile could work from a config file. I just need the actual RGB conversion routine to try out the idea.

I've found a couple of references to some LIBs for finding terminator, and I think a temperature curve could be defined based on optimum settings from day/dusk/night views to make the map readable for all (natural) lighting conditions. At least that's a place to start.

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

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

Better to just point folks here I think: http://stackoverflow.com/questions/6182451/how-to-calculate-the-sunrise-and-sunset-in-javascript All sorts of links to different things related to sun and location.

[mapserver-users] Use the Filter in a WFS 2.0 server
Hi, I'm try to invoke a mapserver set as a WFS 2.0, putting a filter in the querystring. But the response is always empty. I use a spatialite db ad repository. Is it the filter working on wfs 2.0.0 ?
