Hello community,

I know how to create a buffer or multiple buffers around a point feature. But then you always get a ring buffer. How can I create a rectangle buffer ? Can I use a tool or a python script ?

A sample script exists in the help topic
http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002z0000001v000000.htm
which you could modify to suit your purposes.

I suppose one way of getting around this problem is to create the buffers then use the minimum bounding geometry tool to create a rectangle. Not sure if this is the best or most logical way but you would certainly get a square/rectangular area around the point.

Hope this helps

Using the Minimum Bounding Geometry tool (ArcGIS 10) to get a square/rectanble from the buffer polygons is a good idea. The RECTANGLE_BY_WIDTH and RECTANGLE_BY_AREA options are available for ArcView license.

Is there a way I can define the alignment of the rectangles?

No. The minimum bounding rectangle by width or by area is unique in its orientation; so you don't have control over the alignment of the rectangles. A bounding rectangle in a different orientation may not be minimum bounding rectangle by width or by area.

Thank you. I just found a solution (from Aaron at http://gis.stackexchange.com):

1.   Buffer your point feature (ArcToolbox > Analysis Tools > Proximity > Buffer). Make sure to select the correct distance in the linear unit box.
2.    Input your newly created buffers into the Feature Envelope to Polygon tool (Data Management Tools > Features > Feature Envelope to Polygon). Make sure to select the "Create multpart features" box if you have multiple points.

The ENVELOPE  geometry type in Minimum Bounding Geometry tool gives the same result.
