The Green Net National Product: Subproject regarding pollution of the water environment

This subproject is a part of a larger research project at UCPH that aims to estimate the Green Net National Product (GNNP) for Denmark since 1990. The first stage of this subproject constructs longitudinal datasets and maps the ecological status of Danish water bodies.

For more information and preliminary results for streams, see: ThorNoe.GitHub.io/GNNP. Similar work for lakes and coastal waters is forthcoming.

Output

Besides the map book with a map for each year, the script tool creates two longitudinal datasets for further statistical work:

streams_DVFI_longitudinal.csv contains the DVFI values of all streams
streams_ecological_status.csv is for the ecological status of all streams

How to run the script tool in ArcGIS Pro

ArcGIS Pro must be installed and up to date.

Click the green Clone or download button at the top right corner of this GitHub page ^^
Within the downloaded gnnp folder, go to the gis folder and open the ArcGIS Project File gis.aprx with ArcGIS Pro
In the Catalog Pane, open Toolboxes > gis.tbx > WaterbodiesScriptTool. Select the gis folder and Run the script

Update with the most recent data

The most recent data on indicators can be downloaded from the Danish surface water database by opening odaforalle.au.dk in Microsoft Edge. To access the data, it is required that you supply your e-mail address.

For streams:

Go to Hent data > Vandløb > Bundfauna > DVFI-indeks
- Set the from date: In Fra write 01-01-2019
- Set the to date: In Til (optional)
- In the bottom right corner, click Excel (<no. rows> rækker) and save to the gis/data folder as streams_DVFI_2019-.xlsx (overwrite the existing file with the exact same name!)

Run the script tool as described above to update the longitudinal datasets and recreate the map book with the most recent data.

Update with new identification of water bodies in 2022

VP3, the third waterbody plan covering 2021-2027 should be passed by ultimo 2021. Thereafter, an updated MiljøGIS will be published and the Danish Environmental Protection Agency will produce updated linkage tables to report the new identification of water bodies to the EU EPA.

If interested in updating the script for VP3 by then, update the specifications in script.py with names of the new linkage tables as well as the specifications for the updated MiljøGIS map (first, open it with the ArcGIS Pro Geoprocessing tool WFS To Feature Class). In script_module.py, edit the function ecological_status() where it specifies the parameters for calling self.stations_to_streams(). If there is no boolean variable in the new linkage table, modify the function stations_to_streams() accordingly.

Run ArcPy commands in the Anaconda Spyder environment

For a mayor revision of the script tool, one will want to be able to run ArcPy commands within an IDE or text editor.

The version of Python used in ArcGIS Pro is systematically older than the most recent version. Therefore, your preferred IDE is probably incompatible with the ArcPy package as it draws on the ArcGIS Pro installation. To be able to run ArcPy commands, the simplest solution is to set up the Spyder editor as follows:

Clone the Python environment and install Spyder within ArcGIS Pro as explained here.
Likewise, install scikit-learn within ArcGIS Pro for Python data analysis.
Open the Start menu, navigate to the ArcGIS folder, and open the Python Command Prompt within which you
- Open Spyder by typing spyder.
  - Whenever you are to use ArcPy commands, you need to open Spyder through the ArcGIS Python Command Prompt.
Within Spyder, import arcpy to utilize the wide range of ArcPy options.
