Yeahhhhh, right....
Can someone please tell me why Lake Ellesmere (I checked my map) is
green (passed by it only once about 10 years ago on a tourist jaunt to
Akaroa).....?

It may be a false colour created by the satellite cameras. Mind you,
Ellesmere does get pretty soupy at times, they may have caught it during
an algal bloom.

OFF TOPIC :
I don't understand how PHP works - actual ChCh photo full URL is
http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=10923
When I copied and pasted my original (no image id specified) into my browser
just now, I got the Atlantic plankton photo (which has it's own image id) - can
any techies please explain.....?
Thanks,
DS

Which (Atlantic photo) I had previously acccessed as the full link.....

Anyone know what those dark areas above the waimak on the left are
that look like roads with center lines. The bit above them looks like
something from the movie "signs" too :-)
It's called Eyrewell forest.
wtf did *you* think it was :)

Didn't have a clue. Still looks weird. What are all the white dots
(which would actually be quite big) in it?
I'd say those areas are the cleared ones - and the white "dots" are the
large turn around / clear areas for the big logging trucks. Or
possibly, they're the piles of wood. Given they're whiter than the
surround, I'd say it's clear area, hence my former assumption.

No one's probably interested, but the answer might be that the short URL is for
the "image of the day".....

Not bad pic. I grabbed it, then used it as an image_map in POVray
raytracer. The end result looks like a photo taken from 50000 feet
above the Canterbury plains looking down at a 45 degree angle at
Chch. Cool!
I only mapped the image onto a flat object, then angled the camera
down to appear as though its a real location viewed from high above,
but if I could find geographic datasets for height (height-field,
terrain-map etc...) for the area I could render the whole shebang
in true-3D, and do animated flypasts etc...
Kind regards,

Northlands, the Palms, Riccarton etc.

I found this other NASA domain also from the Earth Observatory domain, where you
can do a search for images :

There's data floating around the net for MS Flight Simulator. Can you
use that?
Probably not. I checked out geographx.co.nz and found they had that
data, but the kind of data I'd require for POVray would be akin to
a greyscale elevation map, where the elevation is represented by the
greyscale colour value (black for low elevation, white for high etc...)
I did create a rather inaccurate elevation map by getting the height
of peaks from a NZ Atlas, chose the highest peak on the peninsula
(Mt Herbert, 920m) and drew a 92% grey blob where its peak was, then
drew blobs of varying %grey on all the noted peaks on the entire
peninsula (you're thinking I have too much spare time!) then blurred
the whole thing to create slope leading away from the peaks, played
with colour curves to get sharper peaks and smoother slope definition,
saved it as a PNG file, and used that in POVray to create the rough-as-guts
height field object. With the 2808x2808 resolution of the height-field,
and the 2808x2808 resolution of the image_map (converted from a 1.5MB
JPEG to a 17MB TGA image), POVray still manages to churn out a preview
(640x480, high quality) in less than 20 seconds all up (most of which
is in parsing/loading the maps). My desktop is 1600x1200, and that only
takes about a minute with full-scene anti-aliasing, mostly because
its only image/height_field mapping...
I'd like to get accurate Digital Elevation Maps though, since my map
isn't very accurate (too smooth, not enough detail on peaks/ridges
etc...)
250m DEM data for use in the latest 3D version of OziExplorer?
Expands to 170MB

You also need this file in the same folder

250m cell size is too big. I'm only mapping the banks peninsula
area, so I'll need 50m or 25m (highest possible) DEM. Geographx
guys can convert the data to the format I need, but I'm waiting
for a price for a 25m/50m DEM for the 50x40km area I require...
