Is there an agreement on how many segments to divide road into ?.
A road that's only a few km long would only be created from one segment. A
road that's tens of km long should obviously be created from multiple
But is it reasonable to have many segments, each only half a km long ?
Advantages of multiple short segments -
- the name appears often
- allows details to be varied e.g. maxspeed
- allows road classification to change
Disadvantages of multiple short segments -
- the street name is more likely to obscure the name of cross-streets
- will it appear as multiple streets in a directory e.g. will there be four
"Smith Street"s in "Jonesville" appearing in an alphabetical listing ?
Your thoughts please
