Interlochen, Grand Traverse County, Michigan, United States

re: Interlochen Center for the Arts

The reason the place is called Interlochen is that it lies between two lakes: Green Lake and Duck Lake. The map view shows no lakes.

Ok a question: From where is the data derived to generate the maps?

I like this question because it gives a good chance to share the philosophy and process of OSM.

I have plotted the lakes using bing, I'll leave the name tags for somebody with local knowledge.

There are two primary sources of data used in Open Street Map.

  1. Importing of freely available data sources. (Data sources that may be freely copied / imported, not necessarily data sources that cost nothing.)
  2. Contributed work of many people who, like you, found that something was missing and decided to fix it.

I got started updating several years ago because I found errors and omissions in the map. Instead of having to send an e-mail to a commercial source, wait for them to get around to evaluating my data, update their data, and then sell me back the corrections; I could just fix the error, and it would be freely available to everyone. What's not to like?

You might want to consider doing that for the area around Interlochen, Mi. The "How Do I Get Started With OpenStreetMap" page is a good place to start.

I'd change your answer slightly to emphasise that most of OSM is contributed by volunteers, rather than data imports. Your bullet points suggest otherwise!

It really depends where you are whether the majority of the data is from contributors or imports. Many of the parts of the US I have examined (especially rural areas) still have unmodified Tiger data.

If you click on the documentation tab you can find out where, what and how data is gathered and used.

If I have found the correct place the bing back ground is good enough for tracing around the lakes. So please have a go at mapping. Note: Bing is the ariel view that is supplied by Microsoft to help us, it's a great help.
