The Census Bureau provides shape files for TAZs which do not seem to cover
small counties without metro areas. What I need is a shape file for
townships, ranges, and sections for the entire state of Illinois including
rural counties like Iroquois County. My project deals with land use data.
The maps produced by Landview are excellent for my purpose but they produce
only image files not shape files. Can someone help?
Thank you,

Marie--Unfortunatly you will not be able to get wall-to-wall TAZ
coverage for the state. TAZs only exist where MPOs defined them and in
some some states where the state did the areas outside the MPOs. In IL
you are out of luck, TAZs only exist for the metro areas.
On a side note you also have to be aware of the TAZs shape files you
have. If I recall the ones the CB distributes are "generalized" and to
course.
Would Block Group shape files work?
