Hi Bianca,
But this is exactly the kind of geocoding that MIPro is good at, and
always has been. It's always been there.
All you need to do is build a "StreetInfo" table, with these 5 initial
columns and the road vector as the mappable feature :
ROADNAME Char ( ### )
FROMLEFT Integer
TOLEFT Integer
FROMRIGHT Integer
TORIGHT Integer
The two intervals designate low-to-high house numbers on each side of
the street. Usually the numbers are odd numbers on one side, even on the
other. The direction of the road vector determines the FROM-to-TO
relationship.
MapInfo Pro will automatically detect this table setup and use it for
geocoding. I think the ROADNAME column needs to be indexed, though.
So you don't need to calculate it yourself. Nevertheless the coordinates
can be extracted into columns with these function calls
Vector_Start_X = ObjectGeography ( obj , 1 )
Vector_Start_Y = ObjectGeography ( obj , 2 )
Vector_End_X = ObjectGeography ( obj , 3 )
Vector_End_Y = ObjectGeography ( obj , 4 )

Hi Everyone!!!, My name is Blanca and I'm Peruvian.
Please, I need your help!!
I am planning to geocode using vector analysis formulas and I was wondering
if any of you have ever tried this.
Specifically, I need 2 programs:
a) A program that calculates the beginning and ending X,Y coordinates for a
set of lines (streets), like this:
|---------->----------|
(X1,Y1) (X2,Y2)
b) A program that extrapolates the location of the address using the X,Y
coordinates and the direction of the line, plus an adjustment for left/right
side of the street.
Thanks a lot!!!!
