Summary0000464: Heureka fails to discover some polygon adjacencies
DescriptionHeureka fails to discover some polygon adjacencies
Steps To Reproduce1. Import attached stand register and shape file containing two stands
2. Run Compute Adjancencies from the Tools menu

Result: No adjacencies were found
Expected result: The two polygons share 265 meter border

The following script uses Sql Server's built-in spatial methods and can be used for comparison. In this case a shared border must be at least 10 m to count.

FROM GIS_Polygon_New b

--INSERT INTO TreatmentUnitNeighbour
SELECT p.TreatmentUnitGuid
        ,p.SHAPE.STIntersection (c.SHAPE).STLength() AS LENGTH_M
    FROM GIS_Polygon_New c
    INNER JOIN p ON p.Shape.STIntersects(c.Shape) = 1
    WHERE p.TreatmentUnitGuid<>c.TreatmentUnitGuid AND
    p.SHAPE.STIntersection (c.SHAPE).STLength() >= 10
TagsNo tags attached.

Borders are imprecise. Sometimes overlapping and sometimes not touching.
