One of the first things they did when searching for Jim Gray's boat
was find a satellite
image of the boat
in its berth. So there it is. At MODIS's highest resolution (250m) boats of this size would take up less than 1/10th of a pixel. Hopefully Friend of Nina has access to a much higher resolution and some way to scale it down to a low-res first look.
I had a quick look at landserf and whitebox but both seemed to require ShaktiGurl
's level of GIS expertise to get started. I'll keep looking.
I am guessing they will be hi-res but the imaging sensor
has not been mentioned yet. I am hoping for 10m or less or it will be quite difficult to see something of Ninas size. It will take many images
to get the entire area and hopefully we can get multiple dates.
I don't know of any good open source image processing tools that aren't specific to a sensor
. But I think this will be a visual seach using images
like you see on google earth
. In fact, I could save them as KML files and then anyone could view them using google earth
I could also try to run some target detection to find possible targets in the image and export this to a vector file for others to search and weed out the false positives. It would be helpful to have an ftp account where we could upload/download data for sharing.
I would certainly like to help if I can.
