I'm interested in the routing performance of large road networks in the SpaceNet dataset,
so getting larger imagery or the way to match small patches up to single large imagery is necessary.
In the blog Large Road Networks section 4, that is the same thing that I want to do.
However, I'm unfamiliar with the details.
I notice that patches in SpaceNet road datasets (AOI_2_Vegas, AOI_3_Paris, AOI_4_Shanghai, AOI_5_Khartoum) are 1300x1300,
and they should be cropped from larger imagery like the picture below.
Could you help me with how to figure out the relation between cropped ones and the larger one?
BTW, is it possible to connect roads in different patches, and how?
Thank you very much!
