For maps, more is required than a declaration of "own work". Where do the details in the coastline come from? Pieter Kuiper (talk) 22:17, 28 December 2011 (UTC)An anonymous IP editor has pointed out that the map created by Van Haeften bears more than a passing resemblance to another map available online.
I created this map in Inkscape. The coastline was roughly based on a Google satellite photo and in practice is points from the coastline connected by thick lines rather than a detailed tracing. --Fæ (talk) 22:29, 28 December 2011 (UTC)
Here's the Van Haeften map in question:
Just for fun, I took a screenshot of the Google satellite map of the area:
I overlaid it with Fæ's image at 50% visibility, using the road for positioning and scale:
Notice how different the shape of the lagoon is? Now look at the tourist map with Fæ's image overlaid at 50% visibility:
Interestingly, no scaling was required, it fit perfectly at the sizes downloaded. See how similar the placement of the text is? See how the lagoon is the same shape on both maps, unlike the shape it is on Google?
