natcap.invest.datastack module¶
Functions for reading and writing InVEST model parameters.
A datastack for InVEST is a compressed archive that includes the arguments for a model, all of the data files referenced by the arguments, and a logfile with some extra information about how the archive was created. The resulting archive can then be extracted on a different computer and should have all of the information it needs to run an InVEST model in its entirity.
A parameter set for InVEST is a JSON-formatted text file that contains all of the parameters needed to run the current model, where the parameters are located on the local hard disk. Paths to files may be either relative or absolute. If paths are relative, they are interpreted as relative to the location of the parameter set file.
A logfile for InVEST is a text file that is written to disk for each model run.
