Thoughts - Oops! Shetlands Ain't The Faroes.
Digitizing from Landsat N-30-60_2000 ETM+ at 1:12,500
As my frequenct readers are aware, the 1:12,500 scale is what I typically use when I digitize EVS quality shorelines from Landsat ETM+ mosaics. I am able to distinguish features without having the image become a montage of different colored pixels. If I have a poor quality image, I might work at 1:25,000 to 1:50,000. A great image allows me to work at 1:6,750 occassionally. But typically, my work is done at the 1:12,500 scale.
I loaded this Landsat image into Global Mapper, zoomed in on an island shoreline, and began work. After three hours of digitizing, I decided to zoom out and look at the entire island group, which I assumed was the Faroes. They really looked strange!
Funny Looking Faroes?
I checked out my WVS map files and these Faroes were in the wrong place. They were right where the Shetlands should be. I checked out Wikipedia and located a MODIS image of the North Sea and there, just above the Orkneys, are the Shetlands and to the northwest of the Shetlands are the Faroes. They kind of look alike, but not really.

So, it looks like I am digitizing Shetland shorelines and not the Faroes. It seems that Landsat has dropped the ball on the Faroes. I am certain that they have imaged it numerous times, but none of these images are freely available to the public.
I'll be content to map the Shetlands for now and tackle the Faroes another day.
Enjoy!
