 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 [[contrib:bz10m_roads_network|Network Data Model]] they become links.
-We are working on the meanings of the columns:
+== 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.)
+== Columns of the table ==
+We are working on the meanings of the columns:\\
+**BZ_ROADS:**
 |ID|long integer, the ID for each road segment|
