@lseelenbinder thanks for catching this! @tmpsantos @pozdnyakov where can @lseelenbinder add the test? Are there other invalid geometries that we should skip? |
|
@lseelenbinder I merged before you could add a test for this PR. Do you have one? |
|
I don't, @tmpsantos. I wasn't sure where such a test should go in the testing apparatus. :) |

@lseelenbinder it could be a unit test using gtest. They are inside |

This skips adding invalid geometries (i.e., LineStrings) when encountered.This is a trivial bug to verify based on reading the code. I'm happy to add a test case, if someone can point me to the right place.
