googling earth: in literature

Now, it is not often that one may see a GoogleEarth image in literature. Although I swear I've seen a simple overview map in a published article before, I cannot think of in which journal it was in. Alas, it is not important.

I'm fishing for opinions here. I'm putting together some masterful (if I do say so myself) geomorphic maps for a Fluvail Geomorphology term paper tied into a chapter of my thesis - and the issue of GoogleEarth's place in literature comes to mind. I've been going back and forth between GE and ArcMap. GE helps me find things. Every shapefile I have has a kml/z twin. It runs clean and for the most part, looks just as nice.

Within this term paper, I needed an overview map. One which depicts a broad view of my study area, the Laurentide Ice Sheet margin at 18kya, and a single, clean background.

I tooled around a bit in ArcMap, but the computing power necessary for their terrain basemap and subsequent mediocre quality irritated me - as did conversion of some necessary ice margin shapefiles.

So I turned some layers off (well, all) in GoogleEarth, turned my ice margin on, and got this:



Crisp. Clean. There's colour. There's an ice margin. If you ask me, it looks good. Add a scale and a key and we're there. Now this is just for a class term paper. It will not be heading to Nature Geoscience or Geophysical Research Letters anytime soon (although, every paper is a Science paper, that is, until it is rejected.) I like this map and I intend to use it for this paper.

And therein lies the question: Should it work? Some will say no, some will say yes. Its a broad enough region as to know where it is, what it represents. However, academic is a fickle beast. I wouldn't be the least bit surprised to get a negative comment on this as it may be construed as unprofessional, childish, lazy, etc.

Let me know your thoughts. Comments welcome.
