State of Michigan (SOM) 2015 1.0 vector digital data Michigan State of Michigan http://www.michigan.gov This metadata record describes the vector data used for the 2015 Michigan LiDAR project covering approximately 557 square miles, in which its extents cover Manistee County. This data meets FEMA "Guidelines and Specifications for Flood Hazard Mapping Partners" and USGS Lidar Base Specification 1.0. To acquire detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, dam safety assessments, and hydrologic modeling. LAS and bare earth DEM data products are suitable for 1 foot contour generation. USGS LiDAR Base Specification 1.0, QL2. 24.5 cm FVA. Project Projection, Datums and Units. Projection - State Plane Michigan Central. Horizontal datum - North American Datum of 1983 (NAD83 (2011)). Vertical datum - North American Vertical Datum of 1988 (NAVD88) using the latest geoid (Geoid12a) for converting ellipsoidal heights to orthometric heights.

Each tile is 2500 X 2500 feet in dimension. USGS 2014 Unknown Vector digital data 1200 disk 2015 Ground condition NHD The National Hydrography Dataset (NHD) is the surface water component of The National Map. The NHD is a digital vector dataset used by geographic information systems (GIS). It contains features such as lakes, ponds, streams, rivers, canals, dams and stream gages. These data are designed to be used in general mapping and in the analysis of surface-water systems. (ref. http://nhd.usgs.gov/) As such, the NHD acts as a guide and reference when compiling up to date hydrologic features from aerial lidar data. Sanborn Map Company, Inc.
