Property SpatialIndexLinksPerCell: integer;
This property can be used to define the spatial index creation (part of function NWcreate) to better suit your needs. Optimum value depends on many factors such as typical function calls, type of coordinates, geographical distribution of roads etc. so these notes are just guidelines. If you choose the wrong value, performance will suffer, but results will still be correct:
If you have a network with a geographically even distribution of roads all over the onclosing rectangle:
Primarily coordinate2node function calls: 50-200.
Primarily coordinate2location function calls: 10-100.
Mixed use: 50
If the distribution is very uneven (such as Canada):
Primarily coordinate2node function calls: 5.
Primarily coordinate2location function calls: 1.
Mixed use: 2
Default value is 50.
