The other recent Google Earth innovation is Earth Engine, where you can check out a bunch of interesting visualizations of environmental data. Spurred by something Julian said, I downloaded the MODIS VCF global tree cover change dataset (2000-2005). And then I went to Genesys and downloaded data on wild beans (Phaseolus spp). It was not very difficult to put the two together in Google Earth. In the map below, which just looks at central Mexico, orange means high deforestation, and green afforestation. Is it me, or do germplasm accession seem to be concentrated in areas of high deforestation? Anyway, with a little work, this could be a cheap and cheerful way to identify particularly threatened areas for germplasm collecting.
Who wants to be the first to put crop wild relatives data in Earth Engine?
