City data is improving. Wilderness data is poor. Ocean data is worst. Satellite view is not what we think it is. Oceanic satellite view is not imagery, but just blue paint. If it were imagery it'd show the Arctic as white. It's been white for 700,000 years. It's melting fast, but none of the mapping technology shows that, which makes it hard for us to protect the earth. fixmaps.org (my site)
