line - How to determine right side of the street vs left side?


Example picture


Given the following information, how does the program determine which side is the even-numbered side of the street?



Answer




In this example - because the Y coordinate of the From point is greater than the Y coordinate of the To point - the road therefore runs north to south - therefore the right hand side would be the west and the left hand side would be the east. Is this the kind of logic you are looking for?
