Abstract:
The Boat Ramp Access Coverage provides mapped locations of local boat ramp access facilities. It also includes an ordered database of information linked to these mapped facilities. Knowledge of boat ramp access facilities is imperative for a quick and effective notification and response to potential oil spill situations. This coverage helps to bring such areas within the Michigan counties of Arenac, Bay, Clare, Genesee, Gladwin, Gratiot, Hillsdale, Huron, Iosco, Isabella, Lapeer, Lenawee, Livingston, Macomb, Midland, Monroe, Oakland, Ogemaw, Saginaw, Sanilac, Shiawassee, St. Clair, Tuscola, Washtenaw, and Wayne to the attention of spill planners and responders. The boundaries of these areas were obtained and quality assured/controlled using maps and individual feedback from various public agencies and private sector groups regarding specific sites.
Purpose:
In order to better protect unique commercial, environmental, and cultural resources from oil spills, the Oil Pollution Act of 1990 mandated a coordinated effort by federal, state, and local regulatory agencies and the regulated community to enhance oil spill preparedness and response. This coverage provides the location and attached data for the 25 counties of the Southeast Michigan mapping area. The development of spatial databases and geographic information systems is done pursuant to implementing the preparedness and response mandates of the Oil Pollution Act of 1990.
Supplemental_Information:
These data were prepared at map scales of 1:24,000 and are best used in applications of comparable resolution. In addition, these data were developed to meet specific project objectives related to contingency planning and spill response and therefore may not represent exhaustive feature inventories.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Great Lakes Commission staff working on the Area Contingency Planning project verified all descriptive and spatial attributes and collected confirmation from landowners and/or managers of attributes and boundaries via surveys or direct external review. Spatial data were cross-checked with multiple sources. Quality assurance and quality control for the data were developed utilizing in-house standard operating procedures.
Logical_Consistency_Report:
Data were developed for this layer utilizing multiple primary sources, from federal, state, and local governmental agencies and owner/operators of the boat access sites. These primary sources include USGS 7.5 minute quadrangle maps; federal, state, local and private land manager/owner hard copy and electronic sources; and an exhaustive external review process performed by the primary holders of data. Initial data were supplied by state agencies maintaining boat access records state-wide in hard copy and electronic format. Data was reviewed for location and accuracy at the scale of 1:24,000 on appropriate base maps. Location and attribute information is only as accurate and complete as the information specifically applies to each individual record at the time of data development. Data for these facilities are primarily attributed points, plotted in ArcView 3.2 GIS. These points were generated in 1999 and updated in 2000 based on current information from primary sources but do not necessarily always exactly overlay the base map 7.5 minute quadrangle maps with previous publication dates.
Completeness_Report:
This coverage does not necessarily include all boat ramp access facilities within the given mapping-area. Primarily, the state regulatory agency overseeing these facilities provided the initial source and accurate portrayal of these facilities, but not necessarily all facilities. This layer represents available data as of 2000. Exhaustive efforts were made to compile as thorough an atlas as possible.

Horizontal_Positional_Accuracy_Report:
Horizontal positional accuracy is tested by visual comparison of hard copy check plots to the source materials and verifying the location of the data on screeen relative to other data layers in the same geographic area.

Process_Description:
Locational information and the attached database information for the boat ramp access site coverage were primarily obtained from the Michigan Department of Natural Resources, Division of Fish and Wildlife and county and local park districts. Address cross verification, updating and correction were done through the use of online sources. Additional site and locational information verifications were obtained from the DeLorme Street Atlas, state and local land management agencies and government agencies including the Department of Natural Resources online sites for Michigan. In addition, the DeLorme Atlas and Gazetteer and U.S. Geological Survey 7.5 minute quadrangle maps for Michigan were reviewed for site identification and verification. Point shapefiles for each boat ramp access site were entered directly into ArcView version 3.2 Geographic Information System (GIS) software and displayed against Digital Raster Graphic (DRG) imagery of 1:24.000 scale U.S. Geological Survey topographic maps. Data links were incorporated into these GIS files to match the boat ramp access site data and to appropriate data recordsn. Draft hard copy atlases were prepared form this data, supplied by the Great Lakes Commission, and the USGS's Upper Midwest Environmental Sciences Center (UMESC) in Onalaska, Wisconsin. The UMESC produced hard copy maps in portable document files (.pdf) format at scales of 1:25,000 and 1:100,000. These maps were then reproduced and distributed by the Great Lakes Commission for external review by primary source data holders. All updated, corrected and amended information was then added to the project files and returned to the UMESC for final atlas preparation.
