Re: [JPP-Devel] How to import a table of polygons

[Giuseppe A. <giu...@ya...>]

Hi London,
thanks for your answer.ù
Really I fegure out I can do it using a spreadsheet.
The basic work is to transform, for instance,  a line coordinates: 0,0 0,2 2,2 2,0 0,0 into a wkt string: Polygon ((0,0 0,2 2,2 2,0 0,0)). This is not difficult but sometimes confusing and long.
It would be interesting to explore a way that involve OJ directly using table 

regards

Peppe

P.S. Francisco Helguera from SAIG wrote me that Kosmo has a "Get
lines from points" tool that should work - but no import table.
