The google earth app shows the date as 4/11/2011 (US data format I presume, April 11th, 2011). The google earth measuring tool shows both of these boats we pointed to as being about 55 feet long. So you may be right. Sorry for the red herring but this is good practice at distinguishing boats from above. Does anyone know where Nina was April 11, 2011?

[Friend of Nina]

Thanks Rick, still hoping a boat sights them.


Regarding to imagery if can help locate Nina I'm in.

Remember Nina is 70' with bowsprit about 60' w/o.

I believe Nina crossed the Pacific in 2011. I was in Tonga in Nov 2011 and she was there then. My guess is she came south to NZ shortly after that.

[Friend of Nina]

Exactly she left Tonga and then on to NZ!!

Thanks for the link. I have made a small donation. Wish I could give more. Hang in their folks, they are adrift and waiting for our efforts to reach them.

You're very welcome. Its the least I can do but unfortunately it isn't a big donation, as I have a ton of costs myself at the moment. Just hang in there and with prayer and the combined efforts efforts of many we will bring them back for you. I just wish I could get out there and do the physical search too. My days with the South African National Sea Rescue Institute were very rewarding helping sailors/seamen in peril. I'm an older bullet now though so strength and agility have waned somewhat lol.

I chipped in too. The link from Sissy's post doesn't work but Gord May's link is good.

What is the best way to help at this stage? I'm a friend of Kyle's and going to be travelling to australia soon from nz, totally willing to be a contact if people need someone working in australia, making phone calls, searching images etc. Also what is the link for donating money to this search?

Here is some imagery just out.






Hope you can get this! Cherie

Hi all, My name is Mari and I have been working on processing the imagery that was provided to you for the search for Nina. Just a little on my background - I am a remote sensing specialist and work for the company that makes ENVI, a satellite image processing software. This is what I have found so far (please let me know if I am not clear): - the data are from the DMC sensor (UK based) and include 3 spectral bands that include a green, red and near infrared band. Near infrared is useful for finding materials against water because water is very dark in NIR and other materials can stand out. - Images were taken July 11 at 23:50 zulu time. I am not good with time zones but I think this is about 9-10am in the morning - Each image is about 700mb uncompressed. They have minimal processing and are not geo-located. They do come with additional data to put the data into a real projection (such as UTM) which I have done. These can be exported into a variety of formats but GeoTIFF would probably be the most useful for others to view. I don't know how to get them out to others though. I can't host them from my company servers so I need an independent FTP site to upload them to. Perhaps this is where someone in the CF community can come through - I know someone mentioned they were working on an FTP site. - there are only really 3 images here. The reason there are 6 is that DMC has a 'primary' and 'secondary' image array but they cover (essentially) the same area. - the images probably have at least 50% cloud cover which makes target detection difficult because cloud varies across the scene (think and thin) so the typical processes find a lot of false positives in the cloud. I don't know if there is much I can do here but I will continue to investigate. - DMC has a spatial resolution of 22m or over 70ft per pixel. This makes identification of any material not very likely unless they are more than 22m, and more likely would need to be at least 44m or larger. The images mosaicked together cover about 71x30km. I have attached a screen capture of the area coverage in Google Earth for reference. I am not sure where to go from here. I am looking for image viewing options for others if I do export these to GeoTIFF. I don't think the free version of Google Earth allows you to overlay a full resolution geotiff but it looks like Google Earth pro does. There also looks like there are some free GeoTIFF viewers out there that will show the geo- locations of the files. I would be happy to provide what I have but I need a place to put them so that others can get them.

Google Drive or any other online storage?

Perhaps the source image can be split, so that it gives tiles sized so that a less than commercial grade machine can be used to view them. Remember pcx.

Is 22m per pixel enough to find a sailboat?

[Naamah]

If the images can be split I'd be happy to try take a look. I'm unsure if I'd be able to access something so big. When I get to a PC I'll see if I can access anything (currently using mobile phone).
Fingers crossed these images help!
