Hello to you,
I was answering the request of Sebastian Hudson about polygons
attribute when I found out something I can't explain to myself. What is the
difference between querying the MinX of an object and querying the MinX of
the MBR's object. To me, it was the same thing, but I obtain different
value. I tought MBR was based on Min and Max value of the object. Now I
found it's different. Someone care to explain?
Here's the query:
Select ObjectGeography(obj, 1) "MinX", ObjectGeography(MBR(obj), 1)
"MinXmbr", ObjectGeography(obj, 3) "MaxX",ObjectGeography(MBR(obj), 3)
"MaxXmbr", ObjectGeography(obj, 2) "MinY", ObjectGeography(MBR(obj), 2)
"MinYmbr", ObjectGeography(obj, 4) "MaxY", ObjectGeography(MBR(obj), 4)
"MaxYmbr" from Municipalités_DTMCQ Where Left$(code_munic, 2) ="32" into
InfoBox
Here's an extract of my query's result:
"MinX" "MinXmbr" "MaxX" "MaxXmbr" "MinY"
"MinYmbr" "MaxY" "MaxYmbr"
