Vector Length in MapInfo

Question

Does anyone know how to calculate the exact length of a vector in MapInfo?

Thanks.

Answer 1

I believe you can use

Dim vector_length As Float
vector_length = ObjectLen(Obj, "m")

Answer 2

I would prefere to use CartesianObjectLen instead of ObjectLen

CartesianObjectLen vs ObjectLen

dim o as object
select * from TABLE where Unique Column = Unique Code into sel
o=sel.obj
print(CartesianObjectLen(o, "m"))
