This data bundle contains some of the inputs, all of the processing instructions and all outputs from a single VisTrails/SAHM workflow. This model specifically includes field data of locations with >40% cover of cheatgrass (presence) and <40% cover of cheatgrass (absence). Predictors included rasters derived from LandSat 8 imagery. Details about both inputs are included in the associated manuscript (http://dx.doi.org/10/1016/j.jag.2017.03.009). The three bundle documentation files are: 1) '_archive_bundle_metadata.xml' (this file) which contains FGDC metadata describing the archive bundle. 2) '_archive_raster_inputs.csv' a list of the raster inputs that were used to generate these model results. These are not included in the archive bundle due to size constraints but are identified in this file as well as the metadata document. 3) '_archive_workflow_FinalModel.vt' where FinalModel is the name of the history node being archive in this bundle. Contains a VisTrails/SAHM workflow document which contains the workflow that was used to create these outputs. The remaining data files are the intermediate workflow products as well as the complete spatial and diagnostic model outputs.
