Title: Complicated Buffer Query

...Ye-eees I think that'll work well enough for my purposes... but my table has 1000s of polygons - is there a way to automate this?

I don't have the programming skills and I don't have the time to do it all manually. I really should see if i can get some training in Mapbasic.

Cheers for the help!

Hi,

Just an idea: Create your normal buffer around polygon 1 and then use the combined polygon from all other polygons as eraser on the buffer polygon. Would that do it? This is not exactly what you are asking for, but depending on your data and the size of your buffer it may work.

Kind regards

Hi folks

I am confronted with a bit of a problem and was wondering if anybody had any clues as to how I might get around it…

The situation is this:

I have a table with complex polygons that I need to buffer - only I need to maintain any existing boundaries between polygon objects - I can't have any overlaps.

Is there a way to run a complex buffer that does not buffer any line segment that is a boundary between existing polygons?

I had thought of copying my existing table, converting it to polylines and somehow removing all lines that are unique, (theoretically leaving me with only lines that are a boundary between 2 polygons) and using this table as a "cookie cutter" on the standard buffer result, but that will still leave me with loads of "slices" of polygons I will then need to delete… and I'm pretty sure there are other problems with this idea though that I don't even want to think about…

Any help would be much appreciated!

Cheers
