Topic: Correlation errors
I am trying to use statistical correlation to measure offsets between a pair of GF1 images. The GF1 satellite was launched by China and provide images with 8m spatial resolution. I have asked if the cosi-corr could be used to measure the displacement between the GF1 images, and it is said the cosi-corr could deal with GF1 images after they were orthorectified.
Now, I have orthorectified the GF1 image pair and made a small subset for my region of interest. But, when I started the correlation, I got two errors message saying "CORRELATION_IMG_CCALL --> Images coordinates origins must be a multiple of the resolution for a grided output." and "CORRELATION_IMG_CCALL --> Images connot be overlapped due to their origin and resolution - Origins difference greater than 1/1000 of the pixel resolution."
Please could anyone suggest what the problem is and how to sort this out?
