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
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.
