I have to build the polygons from some polylines it is an area like a main land(with some boundaries) and some islands around it,islands are building polygons and main land is missing,when i have tried to build the polygons in FME.I have snapped all the lines first and used the transformers like reader-linejoiner-polygonbuilder-writer,I am also using ArcGIS,map info and QGIS.

if you use qgis: try vector-> geometry tools >lines to polygons or the plugin polygonizer –  Kurt Nov 19 '12 at 19:10

If you have a polyline feature class and needs to convert it to polygons, use the ESRI Feature to polygon tool. Note however, this requires an ArcInfo/Advanced ArcMap license.

If you don't have an ArcInfo license then download and install this excellent third party tool - Tools for Graphics and Shapes - and use the Convert Polylines to Polygons tool. –  ccn Nov 30 '12 at 17:58
