I have created multiple polygons with some subset of track-lines, with the order of time those points were recorded. Therefore some of the polygons have self-intersection within the polygon.
Is there any way to solve this self-intersection problem for dissolving polygons?
I used "Buffer" in "GeoProcessing Tools" with 0 distance and "Dissolve result". However, some of the polygons didn't merge into the same polygon (green in this picture). The bottom layer with brown polygons were my line-to-polygons constructed polygons.
