Hello all!
 
I've got a file with Lat/Lon organised in the following way:
 
NAME | LATp1 | LONp1 | LATp2 | LONp2 | ... | LONp4
 
Each row correspond to an area coveres by the satellite scene (4 LAT/LON pairs). 
 
Two things are important for my now:
 
1. I need the line in the middle of the polygon (starting from the middle between p1-p2 and ending in the middle between p3-p4 = "Nadir of Satellite look angle")
 
2. not so imporant as 1., I need the Bounding Box for each Row in the file and compare it with an other polygon (ex: National-border,...). The question is: if National-border-Polygon is inside (%-tresshold) of the created bbox, Satellite scene is good, otherwise not!
 
 
Thanks for help greatings Matteo
