MPilot

MPilot is a plugin-based, environmental modeling framework based on a bottom-up, many-to-many workflow that can be represented by a directed (not iterating) graph. MPilot is descended from the Environmental Evaluation Modeling System (EEMS), which was initially a fuzzy logic modeling package based on EMDS.

Installing

MPilot with EEMS can be installed with pip:

$ pip install mpilot

In order to run MPilot with NetCDF datasets, you'll need to install the NetCDF variant:

$ pip install mpilot[netcdf]

Creating models

MPilot models are contained in "command files", using a simple scripting language. Here is an example model, which loads two columns of integer data from a CSV file, sums them, and writes the result to a second CSV file.

A = EEMSRead(
    InFileName = "input.csv",
    InFieldName = "A",
    DataType = "Integer"
)
B = EEMSRead(
    InFileName = "input.csv",
    InFieldName = "B",
    DataType = "Integer"
)
APlusB = Sum(
    InFieldNames = [A, B]
)
Out = EEMSWrite(
    OutFileName = "output.csv",
    OutFieldNames = [A, B, APlusB]
)

Running models

Models are run using the included mpilot program. The following commands will run a model using the EEMS CSV library and using the EEMS NetCDF library respectively:

$ mpilot eems-csv model.mpt
$ mpilot eems-netcdf model.mpt
