The framework serves as the digital base map for State of Michigan government. 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. Version 17 replaces Version 16a as the current version of the Michigan Geographic Framework (MGF). A primary driving force in the creation of Framework Version 17 was the continued reconciliation of the road network and city/village boundaries with current information. The Michigan Geographic Framework is being created to provide: significant cost-savings due to less duplication of effort across agency lines low-cost geographic database for users of GIS a common-standardized product for any area in Michigan a focal-point for establishing partnerships between federal, state, regional, county and local agencies a product that will be a rallying point for creating an ongoing update and maintenance program for transportation and other features like hydrography and municipal boundaries improved communication between agencies involved in geographic information management the cross integration of demographic and natural resource information, and other data sets the ability to look at what-if scenarios that were not possible before. The framework geography is maintained in the Michigan Georef projection system which is a form of an Oblique Mercator projection.

ESRI ArcGIS 10.0.5.4400 true -90.556669 -82.064868 48.284139 41.632056 The geographic structure and attributes of this State of Michigan framework data set was created based on the 1994 U.S. Census Bureau based TIGER line files as well as the Michigan DNR created MIRIS file (a computerized map digitized from USGS topo maps in the 1970s). The attributes originated from the 1994 TIGER files. However, several more recent products were employed as secondary sources to resolve topological, positional and attributional discrepancies. The following sources were available during the creation of the MGF: Michigan Dept. of Transportation ACT51 maps through 1999 ( ACT51 maps are annually updated maps created by the MDOT for the purpose of allocating federal highway funds.) The USPS Michigan ZIP+4 State Directory Copyright 2000 Qualified Voter File project (QVF) maps begun in 1997. (The QVF is a Department of State (DOS) program that manages Michigan's registered voters. The program requires all county, city, township, and village clerks to provide updated and added street, voting precinct, school district and jurisdiction information directly on maps provided by the Michigan Center for Geographic Information.) This source information listed was compared with 1992 and 1997 Michigan State University created aerial photographs as well as 1992-2000 USGS Digital Ortho Quad Photos to resolve conflicts between the current framework geography and the Michigan Department of Transportation (MDOT) Michigan Accident Location Index (MALI). The above source information was used to create Versions 1a and 1b. Framework Version 2a, was improved by using the United States Geological Survey (USGS) 1:12,000 Digital Ortho Quarter Quad (DOQQ) aerial photography to reposition all the named roads in each county. The DOQQs were produced in 1992-1999. Framework Version 3b was reconciled to the 2001 Act51 maps ( see the abstract in this document for further information on the Act51 project). Changes incorporated in version 3b of the MGF are described in the following document: MGF_v3b_Updates Framework Version 4, has been reconciled to the 2002 Act51 maps ( see the abstract in this document for further information on the Act51 project). Changes incorporated in version 4 of the MGF are described in the following document: MGF_v4b_Updates Changes incorporated in version 5a of the MGF are described in the following document: MGF_v5a_Updates This and other documents related to MGF can be found at: http://www.mcgi.state.mi.us/clearinghouse/Docs 1997-01-01 2005-05-01 The framework geography is maintained in the Michigan Georef projection system which is a form of an Oblique Mercator projection.

ESRI Sequential unique whole numbers that are automatically generated. FIPSCODE The county numbering system is based on the alphabetical order of the county names. The numbering begins at 001 with ALCONA and proceeds in odd number sequence to 165 which is WEXFORD. FIPSNUM FIPSCODE as a numeric value. NAME The county name is provided in all capital letters without the word County after the name. For example, the county of Eaton will be provided as Eaton. LABEL County labels are provided with a suffix. For example, the county of Eaton will be provided as Eaton County. TYPE The type will be County for the County Layer. CNTY_CODE The value represents the county that the polygon feature is geographically located. SQKM The values in these three area fields are calculated from the square meter area field in the ArcInfo Polygon Attribute Table (PAT). SQMILES The values in these three area fields are calculated from the square meter area field in the ArcInfo Polygon Attribute Table (PAT). ACRES The values in these three area fields are calculated from the square meter area field in the ArcInfo Polygon Attribute Table (PAT).
