is looking to map the shorelines of the world - “one island, one coastline, one river and one lake at a time.” The best existing vector shoreline data is at a scale of 1:250,000; Mr. Minton decided that this needed to be improved upon and so began digitizing island shorelines (and a few other features) using Landsat ETM+ 2000
. He describes in detail the process he follows
, using Global Mapper
. The completed enhanced vector shoreline data layer is patchy - there are many islands in the world, after all - but a listing of what has been finished is available by clicking on a geographical area on the right side of the blog. Data can be requested
but don’t expect Mr. Minton to be too chatty.
