In any case contiguous signatures, only can be derived from spectroradiometer handheld/satellite based. If you have handheld spectroradiometer data it is nice, but if you don't have, you can generate signature for a pure patch of single species of size about/more than 30*30 meters using Hyperion based hyperspectral data freely available on earth explorer. The patch size may vary depending upon spatial resolution of the hyperspectral data (space borne/ air borne).
