20130101 vector digital data This data set is part of the Michigan Geographic Framework. 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. All the data items described in the data dictionary may not be filled. The fields are present to allow for future enhancement. 20120101 20130101 Publication date Complete Annually -90.219525 -82.422733 46.79023 41.707102 None Railroad FCC code Framework Classification Code Valid codes B11 B14 B32 B33 Active Status Inactive Status.Rail Company Name.
