Today, Michigan has a statewide geographic information systems (GIS) hydrography layer depicting rivers, lakes, and streams that was digitized at 1:24,000 scale during the early 2000s from USGS topographic quadrangles. At 1:24,000 scale, the location accuracy of features can be off as much as 40 feet. The Department of Technology, Management, and Budget's (DTMB) Geospatial Services team is coordinating an effort to improve the GIS hydrography data on a statewide basis.
The Michigan State Police (MSP) 9-1-1 Administration Section launched the Statewide NG911 Geographic Information Systems (GIS) Repository in 2012 to prepare for Next Generation 911 (NG911) GIS data preparation and interoperability. The repository provides a platform for all Public Safety Answering Points (PSAPs) across the state the ability to upload their GIS datasets required for NG911 into a data format aligned with National Emergency Number Association (NENA) standards.
