[OSM-dev] Max nodes in a way?

[Paul Norman]

When splitting data in arbitrary positions (e.g. coastlines in remote areas) I like to go for a maximum of 1000-1500 nodes per way.

 

If you upload ways with the maximum number of nodes and someone wants to refine the geometry by adding nodes they have to first split them.

 

Also keep in mind that admin boundaries will need to be split whenever they intersect another admin boundary.

The API enforces a limit of 2'000 nodes.

Hi,

I am working on some gigantic GPX files with hundreds of thousands of 
points, representing admin boundary polygons. I'm sure these huge ways 
will break something or cause performance to be dreadful, so I am 
planning to split the enormous polygons into a number of ways and tie 
them together in a relation.

What's a reasonable value to assume for the maximum number of nodes in a 
way? 1000? 10000?
