Re: [Flightgear-devel] Aerial images
In the wild, nobody keeps the grass, so you will see more brown rather than green.

Re: [Flightgear-devel] Aerial images
Actually, my grass is green all summer, and so are most of my neighbors and most businesses. I'm in Michigan and we have no shortage of water so people like to keep things green. I sometimes tell my wife not to water so much and that it's OK to let it brown a little, but it's still green. Look at the "blue marble" images from NASA and you'll see that the midwest is much greener than other parts of the US. There are really maybe 2 months when the "wild" grassy areas really turn brown at all around here. -Paul Erik Hofman wrote: It's actually quite understandable. Grass is green in spring.

Only in places like The UK and The Netherlands where there can be quite some rain even during the summer grass _might_ stay green a little longer.

I've yet to find a nice green photo. Do the aerial photo, surveyor guys pick the dry seasons to do all their work in or is USA really as dry as it appears on Terraserver? Seems a little odd to me and I'm curious. :) Is it that important at all ? I mean, it's like Erik said: usually the green areas aren't even green most of the time ... so, essentially "green" imagery wouldn't be suitable for other seasons anymore ... Unless of course one intends to apply some basic color-based filtering: Of course, having colorful imagery in the first place would theoretically enable you to try to approximate the color-changes per season based on the simulator settings, and possibly also country-/region specific profiles - maybe even based on contributing factors such as the relative position of rivers/lakes in the proximity ;-) One would then need to tell FlightGear in what season an image has been created, so that it can generalize spring, summer, fall and winter settings by deriving corresponding changes in color strength, and -density ... sounds a bit like rocket-science, doesn't it ? ;-) -- Boris ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
