Dear list
How can I create a region from a point file when the centroid of that point
and the surface is given?
Thanks for any help
With kind regards

Is there a way for me to convert my data from points to regions? I have
the center points, but I would like to change this to regions. By using
square symbols I'm able to get the desired map, but eveytime I change
zooms, I have to adjust the size of all of the symbols. Is there a way to

Hi, all,
Does anyone have a utility to create a bounding polygon from a cluster
of points? Region only needs to include all points (points can be
slightly buffered, if needed), not necessarily be formed by connecting
the outermost points.
Thanks in advance!

Hi list,
I have bunches of points that need to be grouped together by an common
attribute and then each group converted into seperate region. Does anybody
know of a way to convert the "foot print" or a set of points make into a
polygon / region. I have tried to query for one type an
You could use the Buffer() function, like so:
update MyTable set obj = buffer(obj, 6, .5, "mi")
This turns your points into hexagons with a radius of half a mile. Change
the 6 to a 3 to get triangles, 4 to get diamonds (squares), 5 to get
pentagons, 12 or more to approach circles.
If you don't

Brendan,
I see two ways of doing this in MapInfo without writting any MapBasic code.
1. Convex Hull will put a "rubberband" around your points and convert this "rubberband" into a region.
"The resulting region object(s) ar
I have a database that contains coordinates of 50,000 centroids that make up
grid of 25m square cells. I've seen a solution from the archives that uses
MapBasic to do this, however I don't have MapBasic. Is there any way I can do
this without MapBasic.
The squares have to be orientated to north

Hi Uffe
I am still slowly learning all things MapInfo: when you say 'Remember to
change the coordinate system first by calling "set coordsys table .." in
the mapbasic window.'

There a function in Vertical Mapper.
I think it would help you with what you want.

And it should work seeing that all the points are centroids.

Forgive me if I misunderstood anything. It's quite early.

Uffe's solution worked perfectly for me. Thanks to all who responded.
