MapInfo Pro

Is there a tool out there to calculate the Concave Hull around a set of points in MapInfo?

(not Convex)

I'd be really interested in this too! Keeping my fingers crossed!

I found an old tool called AlphaShapes by Nyall Dawson in Oz and it's on Github with the mb code too.

nyalldawson/mi-alphashapes: Alpha shapes for MapInfo (github.com)

2 functions: Delauney Triangles and the Alpha Shapes (convex hull which can be adjusted via a value which adjusts the result). Quite neat.

This works fine in MI Pro v15 32-bit but only the Delauney Triangles work in 64-bit MI Pro

Hallo,

I've not used github before.  Would someone be able to explain which of the many folders / files I need to download to be able to have a go with this tool?

Thanks,

Alan.

Hi Alan

I went for Version 105 and you just need the mbx file - unless you want to adapt the mapbasic code, then there is the mb and mbo and mbp.

It works in MapInfo v15 >Run MapBasic

Cheers
