Example data & snippet:

Poly.geojson Linestring.geojson

JSfiddle

Even though linestring is not completely contained by polygon, booleanContains function returns true.

It looks like isLineInPoly function only tests midpoints of line segments,

Did I miss something ?

Hey @ubaltaci looks like you're right. Strange enough a simple test like this is actually missing in the package. Thanks for the heads-up.

I just ran into this issue. It's not only just testing midpoints that is a problem, but also if ANY of the mid points are within the polygon isLineInPoly returns true.

this is affecting us too. Any chance we can get a fix before v7? the light-blue and black lines are getting a true from booleanContains in v6.3.0
