BZ10M: Bolzano Roads Network Spatial Table
Import
imp user/pass file=/bz10m/roads_spatial-current.dmp full=y
Current version: 1.0 (9/26/2007)
The table will be called BZ_ROADS.
This is the TeleAtlas table we got from the municipality on July the 18, 2007. The table contains linestrings (in GEOMETRY column), which represent roads segments; In Network Data Model they become links.
Index
The imported table will have its index created automatically. Index is needed in case you want to use any spatial operators (such as finding all segments within distance, retrieving bounding rectangle etc.)
