Run into this same issue on a different dataset, so I can provide additional information that can hopefully help move this issue forward. Version The stacktrace: The GeoJSON{

}Some background context: I'm not using this library directly, I'm using This works on most datasets however there's been a few edge cases including errors being generated from this library such as private $fixUnableToCompleteOutputRing(col: any): any {
getInstance().getLogger().warn(TAG, 'Fixing output ring geometry...');
try {
col = buffer(col, 0.0001);
col = dissolve(col);
}
catch (ex) {
// This happens if we have two polygons that interweaves together too closely
// Applying a small buffer usually corrects it
if (/Unable to complete output ring|Maximum call stack size exceeded/g.test(ex.message)) {
this.$fixUnableToCompleteOutputRing(col);
}
}
getInstance().getLogger().info(TAG, 'Fixed output ring geometry');
return col;
}The hack expands the polygon by buffering it by a small amount, which may not be ideal for everyone's use case, which has resolved most issues. |

I'm poking around the lib a bit to see if I can figure out why this is happening. Maybe its the same cause as #98?
