Minimum bounding rectangle

[Jamie]

Is there a tool anyone is aware of that will create minimum bounding rectangles for input polylines? i've got about 2000 to do.

I have access to:

Mapinfo 12.01

Engage 3D Pro 8

ArcView 10 (i know there is a tool in ArcInfo but we don't have that licence level)

Hi,

If you store all objects in a single table, you can use tableinfo with
TAB_INFO_MINX etc. as argument.

If you want it for one polyline at a time, the MBR functions is all you
need.

In Mapinfo you can use the MBR() function to do just that.

 

I would:

 

-          Make a copy of your input table.*

-          Open your copied polyline table in MapInfo

-          Open the mapbasic window

-          Enter the following into the mapbasic window (replacing YourTable with the actual table name) and hit enter: Update YourTable set obj = MBR(obj)

-          Save the table.

 

This will replace* (make sure you have a copy of the original table!) your polyline objects with MBR polygons.

 

Hope this helps,
