Property ExtendedDataCheck: integer;
If this property is a positive number >0, function NWcreate will perform additional checks of the input data during network creation. This includes check for loop links, double-vertices, self-intersections and sharp turns. This is all reported in the file network_report.txt.
The value of the property determines how sharp the turns should be in order to be reported. A value of 10 will for instance report all turns almost U-turn like. 90 means all turns of 90 degrees or more will be reported. So the smaller value, the sharper the turns has to be, to be reported.
Please note that this is only for turns within a single link and is not related to the turns reported as part of driving directions.
If double-vertices are found, no checks are done for self-intersections and sharp turns.
List of possible return codes:
1: Object is marked for deletion / not geocoded
2: Object is not a polyline
3: Object has >1 parts
4: Object has zero length
5: Object is a loop link
6: Object has duplicate vertices (may mean self-intersecting)
7: Object is self-intersecting
8: Object has a very sharp turn
9: Object has only 0 or 1 vertex
