Hi, Here is the URL for my application http://www.wetlandsofindia.org/kerala/sample.htm When I search as below
District: Palakkad Then select Panchayat option Bloack: Ottappalam Then hit Submit. It shows me the boundary of Ottappalam block but it shows me a line joining the polygon. I am using following query to return the boundary select btrim(astext(transform(geomunion(geometry), 4326)),'MULTIPOLYGON ()') from k_panchayat where district like '%$district%' and block like '%$block%' group by block It returns me a single polygon only but somehow I do not understand from where the line is coming. I am looking for the solution.
