Michigan Resource Information System (MIRIS) Water Wells
The MIRIS Water Wells data set is a series of digital files containing the location of verified municipal and private water well sites compiled from the Michigan Department of Public Health, Water Well and Pump Records. Digital files contain coordinate locations, elevations, and attribute information associated with the well records, such as static water level, geologic formation, use, etc. This map series is maintained by the Michigan Department of Natural Resources', Michigan Resource Inventory Program (MRIP).
The Michigan State Plane Coordinate System is used to internally store the x,y position of all lines, points and areas. This system separates the state into 3 zones. The north zone contains the entire Upper Peninsula. The central zone contains the counties including the north of Mason, Lake, Osceola, Clare, Gladwin and Arenac counties. The south zone contains the remainder of the Lower Peninsula. Coordinate positions are based on the North American Datum of 1927.
Map features are separated into different levels. Files do not contain topological relationships of map features, but can be used to create a topologically structured data base.
MIRIS files are created in an Intergraph IGDS vector format and can be translated to Data Exchange Format (DXF). In addition, non-graphic well files are dBase/Foxpro compatible.
Archival and Access Information
The MIRIS Water Well files are archived by the Michigan Department of Natural Resources', Michigan Resource Inventory Program (MRIP).
Maps are available for purchase from the MDNR in both digital and hardcopy formats. They can be ordered by county, township, quadrangle, or 36 sq. mile area. Here is a price list.
Digital MIRIS Water Well files at the county level are available for purchase through the Consortium for International Earth Science Information Network (CIESIN).
Data Acquisition/Collection Summary
Water well records are compiled from Michigan Department of Public Health, Water Well and Pump Records. Water well files are continually updated as new records are added.
Other datasets maintained by the MDNR include Base Maps (Product Number 100), Land Cover (Product Number 200), and Soil Types (Product Number 300).
Additional data sets may be located through CIESIN's Gateway.
