The subset tool in SNAP 7.0 (raster -> subset) is generating unusual pixel coordinate values when I input geo-coordinates (West=-83.0, North=28.0 and fixed full width) for the following MERIS image:
The corresponding pixel coordinates given by the subset GUI are:
Scene start Y = 993
Scene end Y = 3585
However, when I view the MERIS image in SNAP I noticed that the 28 degree North line has the following pixel coordinates: (Y=1000,X=0), (Y=575,X=2300), (Y=78,X=4480), which makes sense.
Hence the minimum pixel coordinate that the 28 degree North line is 78 on the right-hand side of the image. This would mean that,
Scene start Y = 78 (…right?)
When I run the Subset GUI (with Scene start Y = 993 and Scene end Y = 3585) I noticed that the upper right hand side of the image only goes to a latitude of 25.72 degrees North.
I’m just wondering if this is a bug.
