InVEST python read in pollination_willamette.invs.json

[jdouglass]

Hello @sibylles ,

Yes, you can provide all of your input parameters to the InVEST pollination model through this JSON file. Filepaths can be relative or absolute paths. See below for a few examples.

As @edavis mentioned in another thread, you would use the datastack file from the command-line by adding the -d flag and providing the path to your datastack file there:

Starting an InVEST python model

Hi sibylles, that’s a good start! To run an InVEST model from the command line, you need to specify the model name, the path to a datastack (a JSON file that specifies the inputs), and the path to a workspace directory (where you want the output files to go). The format looks like this: invest -vvv run <modelname> -d <datastack json file> -w <output_workspace> and you can get more info about commands and options in the Invest CLI documentation (and/or by running invest --help). You can stor…

Relative path example

When using relative paths, the paths are relative to the location of the .json file. So if this .json file is located at C:\datastack.invest.json, then farms.shp would be expected to be found at C:\farms.shp. The guild table would be expected to be found at C:\my_folder\guild_table.csv.

{
    "args": {
        "farm_vector_path": "farms.shp",
        "guild_table_path": "my_folder/guild_table.csv",
        "landcover_biophysical_table_path": "landcover_biophysical_table.csv",
        "landcover_raster_path": "landcover.tif",
        "results_suffix": ""
    },
    "invest_version": "3.7.0",
    "model_name": "natcap.invest.pollination"
}

Absolute path example

These json files can also have filepaths defined as absolute paths, specifying where, exactly, on disk the file is located. Using absolute paths, you could store your JSON file anywhere on the hard drive and be able to access files anywhere on your hard drive.

{
    "args": {
        "farm_vector_path": "C:\InVEST_data\Pollination\farms.shp",
        "guild_table_path": "C:\InVEST_data\Pollination\guild_table.csv",
        "landcover_biophysical_table_path": "C:\InVEST_data\Pollination\landcover_biophysical_table.csv",
        "landcover_raster_path": "C:\InVEST_data\Pollination\landcover.tif",
        "results_suffix": ""
    },
    "invest_version": "3.7.0",
    "model_name": "natcap.invest.pollination"
}

Hope this helps,
James
