The State of Michigan Department of Natural Resources has divisions for Forestry, Fisheries, Wildlife, and Parks and Recreation. Much of their spatial data is made available through an ESRIArcGIS Online Hub.
Add to this table data sources that could or have been used to verify data in Michigan from the DNR - for import processes see Import.
This dataset contains boundaries of state parks, forest management units, wildlife areas, recreation areas, and other collected named property holdings as part of the comprehensive strategy for land retention, acquisition, and disposal. It appears to be frequently updated by the MDNR.
This dataset contains non-motorized trails such as bicycle, horse-riding, and hiking paths. This dataset is updated weekly and appears to be the authoritative source from the Michigan DNR for mapping these features.
This dataset contains water trails. This dataset seems to be updated weekly in conjunction with the Non-Motorized Trails data and appears to be the authoritative source from the Michigan DNR for mapping these features.
This dataset contains Bicycle and mountain biking routes, often in conjunction with trails with primary designation for hiking, so perhaps may better mapped as separate route relations. This dataset is updated weekly in conjunction with the Non-Motorized Trails data and appears to be the authoritative source from the Michigan DNR for mapping these features.
This dataset contains horse-riding trails. This dataset seems to be updated weekly in conjunction with the Non-Motorized Trails data and appears to be the authoritative source from the Michigan DNR for mapping these features.
This dataset contains cross-country ski trails. This dataset seems to be updated weekly in conjunction with the Non-Motorized Trails data and appears to be the authoritative source from the Michigan DNR for mapping these features.
This dataset contains dirtbike trails. Consider tagging with motorcycle:type=offroad to clarify the types of motorcycles suitable for trail use. This dataset seems to be updated weekly in conjunction with the Non-Motorized Trails data and appears to be the authoritative source from the Michigan DNR for mapping these features.
This dataset contains off-road motor vehicle trails managed by the Michigan Cross Country Cycle Club "MCCT". This dataset is a subset of the DNR Designated ORV Routes data source with the difference being operator=*. This dataset seems to be updated weekly in conjunction with the Non-Motorized Trails data and appears to be the authoritative source from the Michigan DNR for mapping these features.
User account responsible for coordinating monitoring of deviation from source for verification, errors, etc. Possibly could be primarily done via software or script, but someone should still be a point of contact and making sure any automated alerts are being monitored. Responsibility shifts from Import (coordinating the import) to maintainer (making sure the data stays fresh and current). Anyone can claim this role, but should be responsive to messages via change-sets, OSM lists, and/or direct messages.
