Linda Rockwood owns Mohawk Valley GIS (in Herkimer, NY where my car needed attention last spring) and in concert with the local snowmobile organizations has moved the old dated, regional paper snowmobile maps online. The online app, The New York State Snowmobile Trails Interactive Map and Trip Planner, is free, but there will be a nominal charge to download the data for use in satnavs. The data includes trails and info on gas stations, restaurants, snow mobile dealers and other relevant snowmobile POIs.
While she notes three groups that the site/data target (”... the local riders who need to know if the trail routes have changed since last year… regional riders can learn about a new route or establishment… riders from all over the Northeast.), she’s also doing some good local PR for her business.
The app, by the way, is built on Manifold IMS.
