    // remove excessive decimals from splitter
    // to avoid possible approximation issues in rbush
    var truncatedSplitter = truncate(splitter, {precision: 7});

    switch (splitterType) {
    case 'Point':
        return splitLineWithPoint(line, truncatedSplitter);
    case 'MultiPoint':
        return splitLineWithPoints(line, truncatedSplitter);
