 <h2>DESCRIPTION</h2>
 
-<p>The Multivariate Environmental Similarity (MES) surfaces was proposed by Elith et al (2010) and originally implemented in the Maxent software. They described the MES approach as: "The multivariate environmental similarity surface (MESS) calculation represents how similar a point is to a reference set of points, with respect to a set of predictor variables (V1, V2, ...). The values in the MESS are influenced by the full distribution of the reference points, so that sites within the environmental range of the reference points but in relatively unusual environments will have a smaller value than those in very common environments."

-<p>The latter two are useful to distinguish areas where only one or few of the variables have values outside the range of the reference set and areas where many variables have values outside the range of the reference set.

-<p>The reference points can be a binary raster layer (with 1 representing presence and 0 representing absence) or a vector point layer as reference points. Any sample of interest can be used for the reference set. Examples are points representing occurrence records for the species and areas that represent protected areas.

-<p>To compare e.g., current and future environmental conditions the user needs to define a reference set of environmental variables (env_old) and a set of future environmnental variables (env_new). This is for example used to identify areas with novel future climates.

-<p>One can also test for the similarity between two different areas. For this one needs to provide a set of environmental variables (env_old) and a reference layer (ref_rast) for one region and a second set of environmental variables for another region (env_new).
