Re: [UrbanSim-Users] Are there documents to expand on the Users' Manual, sections 9.4 to 9.7?

Rick,

You cannot automatically generate tables that are necessary for a
simulation. But we do provide an example set of tables in our Eugene
database that can be downloaded from our website and converted to a
mysql database. Lots of our users use it as a starting point and modify
those data to their region.
