I was replying to the assertion by Anthony that interpolation doesn't specify which house numbers are present between two numbered nodes - just that some unspecified number is present. That doesn't seem to be the original interpretation of the "addr:interpolation" tag. It's not how I use it. I use it to assert that every house number between the two numbered nodes is present - according to the interpretation assumed. With the original post asking about when a regular number is missed - I agree with Tobias that something like addr:interpolation=step, step=x Or even we could just use addr:interpolation=x to mean that only every x numbers are included between the first and last So 1,5,9,13 could be tagged addr:interpolation=4 That seems like a reasonable suggestion and a simple extension of the existing scheme - extensible to any regularly increasing series of numbers that may be found anywhere in the World. addr:interpolation=all would then effectively be identical to addr:interpolation=1 addr:interpolation=odd/even would then effectively be identical to addr:interpolation=2 _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
