1) I assume
you got:
objectA Entirely Within objectB
2) An object
can't be both: If it's entirely in then it can't be just partially
in. If you mean "both those that are partially, and those that are
entirely within" then you need to join the two operators with
OR:
...
objectA Partly Within objectB
or
objectA Entirely Within objectB
3) If an
object's entirely outside then it's not partly within:
....
NOT
(objectA Partly Within objectB)
4) Again An
object can't be both: If it's entirely ouside then it can't be just
partially outside. If you mean "both those that are partially, and those
that are entirely outside" then you need to join the two operators with
OR:
...
NOT( objectA Partly Within objectB
or objectA Entirely
Within objectB) ... I THINK!!!

Subject: [MI-L] Query for determining Entirely Within/Outside of Buffer
Greetings everyone!
Does anyone know how to create a query that determines the following:
1) Census Tracts that fall "Entirely Within" a buffer object
2) Census Tracts that fall "Entirely and Partially Within" a buffer object
3) Census Tracts that fall "Entirely Outside" a buffer object
4) Census Tracts that fall "Entirely and Partially Outside" a buffer object.
For some reason when I tried doing part of #2, (trying to get the tracts "Partially Within" - I tried both "Contains" and "Within"),
the query did not pick up ALL of the tracts that actually did fall a bit within the buffer.
Is there a reason why it is not picking up all of the tracts?
For #'s 3 and 4, I have noooo idea of what operators/formula to use.
Can anyone help?
Thanks so much!
:) Akua
