Hi,
Today I have patched two tools :
1. Osm2Poly so that it processes the results of the Shp2Osm from the census data.

2. Osm2PgSql so that it processes the results of the Shp2Osm from the census data.

And as the result, I can now split osm data via the ZipCode.
The next step I need to check these ZipCodes with multiple ranges.
And the I will upload the results for NJ to the archive.org server.
