- Create Polygons from Point data
Is that any way to create polygons from point data using value from one field in Point data as key for polygon?
Just in case you are talking about achieving this in Manifold using the GUI, you can link a set of data of form:
to achieve what you are looking for. Select Link Drawing from the file menu and set up the data source (Data can be external or in a Manifold table). Make sure you set the LineID item in the Link drawing dialog to Poly_ID and, on "OK", Manifold will create two drawings, one of points and another of lines. Verify the projection of the lines drawing then unlink the drawing and use the "Bounded Areas" transform to get your polygons.
Note that the input points need to create closed sets of lines for this to work (i.e. Point 1 and Point Last need to be identical)
I'm sure others have more elegant solutions!
