Relationship between u&v components and v magnitude
I have got two doubts about the extractions:
1) Extrapolating data almost in the same polyline in the same sequence of images, I ascertained that u&v components are non the v magnitude components along x,y axes, infact it never happens that in the same point: vmagn = radq (u^2+v^2). Did I do a mistake? Or is this correct? And if this is correct, which is the righter parameter wich represent the vector velocity? I have to be sure about this topic, because I have to represent the data in a vector map on surfer.
2) Is it possible to save the polyline to be sure to extract differents types of data on the same polyline?
Thank you Alice
