Description: This data set is part of the Michigan Geographic Framework. The framework serves as the digital base map for State of Michigan government. Currently the geographic framework contains features including roads, rivers, lakes, streams, railroads, political jurisdiction boundaries, school district boundaries, census area tabulation boundaries and legislative district boundaries. Specifically, this Michigan base map will consist of an Arc Info coverage which includes features and attributes based on the current TIGER/Line Files, base map features based on both the Michigan Department of Natural Resources (MDNR) Michigan Resource Information System (MIRIS) Files and an enhanced linear referencing system built from the Michigan Department of Transportation (MDOT) Michigan Accident Location Index (MALI). The Geographic Framework will serve as a common and standardized infrastructure on which all GIS users of 1:24,000 scale map data can build their applications. At the heart of the Geographic Framework will be the ability to administer programs that use location-based information and need to relate one database to another geographically. Version5a replaces Version4b as the current version of the Michigan Geographic Framework (MGF). A primary driving force in the creation of Framework Version 5a was the continued reconciliation of the road network and city/village boundaries with the roads and boundaries as defined on the ACT51 maps. For further information on ACT51 see: Changes incorporated in version 5a of the MGF are described in the following documents: MGF_v5a_Updates, MGF_v5a_Trunkline_Updates These and other documents related to MGF can be found at:

Description: The Adjusted Census Urban Boundary (ACUB) Layer is a single polygon representing the boundary of an individual ACUB. The Adjusted Census Urban Boundary includes the following area: urban cluster area (where minimum population is 5,000) or urbanized area as designated by the U.S. Census; the entire corporate limits of any incorporated city or village designated as partially urban by the Census; and adjacent area which meets specified criteria and is agreed upon by MDOT in cooperation with the responsible local officials. Adjusted Census Urban Boundaries are subject to approval by the Federal Highway Administration.

Description: 1990 Census Tracts from the Michigan Geographic Framework (MGF) base map. Census tracts are small areas created for statistical purposes that usually average about 4000 people.
Description: 1990 Block Groups from the Michigan Geographic Framework (MGF) base map. Block groups (BG’s) are combinations of census blocks within a census tract or BNA that share the same first digit in their identifying numbers. For example, BG 3 within a particular census tract comprises all blocks numbered between 301 and 399. A census tract or BNA contains a maximum of nine BGs. BG90 consists of the 6 digit tract number followed by the 1 digit block group number.
