[Talk-us] State Open Data

[Clifford Snow]

Adam,
Thanks for adding Vermont.

At some point I'd like to do like you did with surfaces. One of the
problems I run into is that every agency seems to have a different list of
surfaces. We'd should probably try to create a conversion chart to map
different names into OSM surface types.

For example, USFS roads has the following surface types

 AC - ASPHALT

 AGG - CRUSHED AGGREGATE OR GRAVEL

 AGG - LIMESTONE

 AGG - SCORIA

 BST - BITUMINOUS SURFACE TREATMENT

 CSOIL - COMPACTED SOIL

 FSOIL - FROZEN SOIL

 IMP - IMPROVED NATIVE MATERIAL

 NATIVE MATERIAL

 NAT - NATIVE MATERIAL

 OTHER - OTHER

 PCC - PORTLAND CEMENT CONCRETE

 PIT - PIT RUN SHOT ROCK

 P - PAVED

 SOD - GRASS


>From Okanogan county in Washington they have

 D

 d

 null (which has the highest count)

 P

 G

The states metadata can help us build a conversion to OSM surface types;


Clifford
