11:08 * mashi yawns
11:36 * nhv brews a pot of fresh coffee
11:38 >> #punt JOIN mazop (n=mazop@dsl-67-61.utaonline.at)
11:43 * mazop yawns back
11:44 * mazop renaming #punt to #yawn ? ;)
11:45 < nhv> pictures from the bottom of the sea  http://www.vso.cape.com/~nhv/files/MOSAIC_2B_50.jpg
11:46 < mazop> wb norman !! .... saw the scans you posted in #worldwind - have fun by stitching 400.000 pics together ;)
11:46 < ShockFire> can't wait to see those in WW/Punt ;)
11:46 < mazop> yea....first 0.01m res pics ;)
11:47 * nhv thinks someone will have to write an osgPlanet to WW converter
11:47 < nhv> oh waait   osgPlanet uses OGC  WMS
11:47 < mazop> mashi maybe ??
11:47 < nhv> :-)
11:47 * mazop tries to wakeup mashi .....
11:48 * mazop KNOCK KNOCK
11:48 < nhv> mazop  maybe you could pass that link along to George  "pleora from the deep"
11:48 < mazop> so you had fun out there norman ?
11:49 < nhv> felt right at home
11:49 < mazop> i will !! ... still working on your award norman
11:49 < mazop> btw. the most important pleora issues are solved now ?

11:56 < mazop> norman: "bottom of mthe sa" means how deep ?
11:56 >> SignOff: nhv (Read error: 104 (Connection reset by peer)) [#punt]
11:56 < mazop> "bottom of mthe sa" = bottom of the sea .....
11:57 >> #punt JOIN nhv (n=nhv@dsl0-1.cape.com)
11:57 * mazop ...has to ask quick now
11:57 < mazop> norman: how deep ? ...
11:57 < mazop> ...the scans i mean...
11:58 < nhv> ~25 fathoms  approx  150 meters
11:58 < nhv> er  I mean  50 meters
11:58 < nhv> or 150 feet
11:58 < mazop> but sure you need extra-light down there ?
11:59 < nhv> oh yes
11:59 < nhv> it is all artificial lighting  esp at night
11:59 < mazop> and it takes how many pics/min ?
11:59 < nhv> I was taking 4 frames per second most of the time
12:00 < nhv> ~250 pics per minute
12:00 < mazop> and the res is ? ... i mean how big is one pic
12:00 < nhv> those snaps are quarter resolution in that mosaic
12:00 < nhv> 1280x1024 12 bit GBRG Bayer space
12:01 < mazop> so all the 400.000 pics are how many GB ?
12:03 < nhv> pics are about 2.5 meg  each
12:04 < nhv> or about 6 gig a minute
12:05 < mazop> hmm... so all together ca. 1 TB
12:05 < nhv> oops  about  629,145,600  or 600 meg a minute
12:06 < nhv> 1280*1024*2*4*60*60 = 37,748,736,000  or 37 GB an hour
12:07 < nhv> raw data
12:07 < mazop> ok... better stop calculating now ;) ..... one thing is sure anyway: big load of data
12:07 < nhv> 3 times that large as RGB Tiffs
12:08 < mazop> about 26h scanning = ca. 1 TB data ...
12:08 < mazop> = ca. 400.000 pics...
12:08 < nhv> you got it
12:08 < Nowak> nhv: 2 * 4 ? why do you waste 25% ? :D
12:09 < nhv> would be great if the Pleora could do RealTime Jpeg2000 compression
12:09 < mazop> one day i woulod like to know how you do that 'stitching together.......
12:09 < mazop> i will poke george about that ;)
12:09 < nhv> Nowak  what do you mean waste
12:09 * nhv hasn't had any coffee yet
12:09 < nhv> so be easy with me  :-)
12:09 < Nowak> 12 bit data extended to 16 bit
12:10 < nhv> ah
12:10 < Nowak> 4 bands so 2 bytes
12:10 < nhv> true
12:10 * mazop has a frech cappuccino next to him ;)
12:10 < nhv> ah  this is beyond my control
12:10 < nhv> the hardware does this
12:11 < nhv> I have a hardware jp2k board  but I need to do this after I get the data from the GigE
12:12 < nhv> woul dbe great to cut down the bandwith needed and do this before the GigE conversion
12:12 < Nowak> hw j2k hmm how fast is it ?
12:13 < nhv> in hardware I can currently do 2k x 15 k 16 bit @ 30 fps  lossless
12:13 < nhv> almost lossless
12:13 < nhv> 2k x 1.5k
12:14 < nhv> this is another project  and is an expensive custom built  board
12:15 < nhv> but there are FPGA cores for this
12:15 < Nowak> Maybe i should make dstile hw board then ? :D
12:15 * nhv has been working on doing jsut that  well the equiv of that  :-)
12:16 < nhv> oh my board is a decompressor also  :-)
12:16 < nhv> same bandwidth
12:18 < nhv> ah new link for 'scallop mosaic'   http://www.seascallop.com/
12:22 < nhv> going to make my colorizer adaptive wrt to altitude when i get Endor setup
12:22 < nhv> oos wrong channel
12:23 < mazop> --> "HabCamGang66" = looks lik a nice crew ;)
12:27 < nhv> that is me on the right
12:30 < mazop> capt. norman .... i thought thats you ;)

18:42 < nhv> mazop   http://www.vso.cape.com/~nhv/files/MOSAIC_2B_A.jpg
18:43 < mazop> nhv: thats originals ? i mean : not compressed ?
18:43 < mazop> res= ??
18:46 < nhv> right ful scale
18:46 < nhv> color corrected
18:46 < nhv> revised color correction scheme
18:47 < mazop> one shell is how big in nature/reality...
18:47 < nhv> originals look a little better then jpegs but are much larger
18:47 < mazop> ...or better.....how wide are the stripes the camera scans ?
18:47 < nhv> the large ones are a little bigger then your palm
18:48 < nhv> eg they fit in your hand
18:49 < mazop> ok....so the stripe the camery scans is ca. 0.5m-o.7m wide i guess
18:50 < nhv> probably  we were aimig for a meter
18:50 * mazop wonders how many square-meter /feet all those 400.000 pics covers ....
18:50 < nhv> I haven't calculated that exactly for thes images yet
18:50 < nhv> 300,000
18:50 < nhv> :-)
18:51 < nhv> we figure we do about 6 km an hour approx a meter wide
18:51 < mazop> yes...i see. they do not overlap like areals (areals overlap about 60%)
18:51 < nhv> I need to up the camera frame rate
18:51 < nhv> I hope I have enough overlap in these
18:52 < nhv> we had more the earlier cuise
18:52 < nhv> must have been towing a little slower
18:52 < mazop> =pleora issue ;)
18:52 < nhv> no
18:52 < nhv> just my brain fart
18:52 < mazop> hehe
18:53 < nhv> these are pretty amazing though
19:00 >> dpatton_away is now known as dpatton
19:01 < mazop> norman, how do you to the mosaic / stiching together ?
19:01 * dpatton waves
19:02 < mazop> hi dave
19:02 * dpatton no pun intended ;-)
19:02 < dpatton> nhv: I was just going to ask you a question or two about mosaicing images, if you have a moment
19:04 < dpatton> nhv: you use ossim for mosaicing, correct? And you said it's better to use it for mosaicing than GDAL, correct? Does that hold true for doing processing in a single-processor environment?
19:05 < Nowak> dpatton: gdal is just data abstraction / reprojection library
19:06 < Nowak> dpatton: whine ossim is that + 100 things more :P
19:07 < dpatton> I have imagery that covers Canada - one 'layer' at 1:250,000 with complete coverage, one at 1:50,000 with partial coverage
19:08 < dpatton> That could produce two layers, or one at 1:50,000 with voids filled by 1:250,000 imagery
19:08 < dpatton> would 'filling the voids' be easy/difficult?
19:08 < Nowak> if the voids are marked somehow
19:08 < Nowak> like 0,0,0 pixels
19:09 < Nowak> then simple as adding one param to gdalwarp
19:10 < dpatton> here's the coverage maps:
19:10 < dpatton> http://members.shaw.ca/cismaps/toporama/cover-canada-250.jpg
19:10 < dpatton> http://members.shaw.ca/cismaps/toporama/cover-canada-50K.jpg
19:11 < dpatton> There are a total of 980 of the 1:250,000 scale map images, and 6,992 of the 1:50,000 scale map images
19:14 < dpatton> Nowak: do you have a rule of thumb for how you select the LZTSD value? It changes in northern Canada, but the 1:250K images cover 2 degrees longitude by 1 degree latitude, and the 1:50K cover 0.5 longitude by 0.25 latitude
