I am a student in the Estonian University of Life Sciences, specialized in Geodesy ( 3rd year) and I am new to the SNAP program. I have some questions regarding my bachelors study about Sentinel 2a satellite imagery. The computer I am doing my work with has Windows 10 and the image in question is: S2A_OPER_MTD_SAFL1C_PDMC_20161206T084303_R036_V20151003T094016_20151003T094016.xml.
I am trying to classify this image, but there are some problems and questions:
- I have read from your site that before subseting I should resample the satellite image. Do i have to save this before subseting because when I try to open the RGB picture of the resampled photo it does not open. The program only shows a gray view of the image. I have already tried to save the image, but it does not work and sends an error.
- Should the subsetted images that I have chosen have the same size on the screen view?
Any help is greatly appreciated,
