Hello,

Is it possible to combine one or more geometry shapes to one new geometry shape and store it in a Database?

Kind regards,

Hi

First of all, what databae do you want to use.
What operation do you want to process?
- joining geometries into one geometry
- collecting a bunch geometries as GEOMETRYCOLLECTION

Please give us more detailed information

I want to join 2 or more geometries into one geometry.
I'm using SQL Server

Kind regards,

Hi,

Have a look at http://www.codeplex.com/Wiki/View.aspx?ProjectName=SharpMap&title=NetTopologySuite%20Data%20Provider

NTS supports many spatial operations. Your case will also be
covered by the library.

I'm now using NTS.

The problem is that the new combined geometry doesn't match the ConvexHull of all the geomerties it was made of. Can someone point me in the right direction for union geometries.
