https://community.esri.com/t5/new-to-gis-questions/issue-with-feature-to-polygon-function-incomplete/m-p/1520580#M2032 <P>Hi- I have a feature layer that is a NOAA coastlines file. It is composed of a bunch of tiny polylines. I am trying to create a polygon on the area enclosed by these polylines. However, I keep only getting half of the polygon I need. I have tried dissolving the initial feature layer so that there is only one continuous line which has not worked. I have, under the assumption that there is a gap somewhere, tried to snap together all the polylines along their vertices. I have also tried the function "extend line" but that has been running literally all night with no end in sight. Does anyone know what I need to do in order to get the entirety of the polygon I am after?&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P> Tue, 13 Aug 2024 14:52:33 GMT SarahStagner 2024-08-13T14:52:33Z https://community.esri.com/t5/new-to-gis-questions/issue-with-feature-to-polygon-function-incomplete/m-p/1520580#M2032 <P>Hi- I have a feature layer that is a NOAA coastlines file.
