[seek-beam] GARP

[Dan Higgins]

Hi Cory,
    In answer to your question, when the Kepler ASC To Raw  actor is 
used to combine a set of *.asc layers into a *.dxl file set for GARP, 
all the input layers do need to have the same cell sizes and extent. 
However, if they do not, there are some other Kepler actors that can be 
used to preprocess the asc grids. For example, the GridRescaler can be 
used to convert the larger extent layers to a finer extent and matching 
scale, or the finer extent layer can (if I remember correctly) be 
extended to a larger extent with NO_DATA values inserted for points 
outside its current size.
    One other point - GARP in Kepler uses a different format for 
occurence locations than Desktop GARP. Kepler assumes a single species, 
so the occurence data is just 2 numbers per line (longitude, latitude).
