    54 '''NOTE''' this is valid as of before r3528, should be rechecked now. Focus is on MCIndexSnapRounder now.

    5654Having detected a difference in noding I've produced a testcase to read a geometry and perform noding on its linework.
    5755The JTS version is [attachment:ScaledNoderTest.java]
    58 
    59 The image below shows difference between GEOS (yellow) and JTS (cyan) noding results with [attachment:bufrob4.wkt] input.
    60 
    61 There are two nodes in both version, only JTS is anchoring the line going down to the node on the left while GEOS is anchoring it to the node on the right.
    62 It's interesting to note that the input (red line) is closer to GEOS result, not JTS.
    63 Also it is to be noted that the horizontal segment is a duplicated edge in JTS which then results in one edge more than the GEOS counterpart.
