Creating a case study on sensitivity and uncertainty analyses for Oregon wind siting.
- data
- raw_data: the raw data integrated in the analysis (Note: original data name and structure were kept except when either name was not descriptive or similar data were put in same directory to simplify input directories)
- intermediate_data: disaggregated processed data
- submodel_data: processed data for analyzing in the wind siting submodel
- suitability_data: final suitability data for offshore wind area region
- rank_data:
- sensitivity_data:
- uncertainty_data:
- code: scripts for cleaning, processing, and analyzing data
- figures: figures generated to visualize analysis
- methodology: detailed methods for the data and analysis
Note for PC users: The code was written on a Mac so to run the scripts replace "/" in the pathnames for directories with two "\".

- BOEM Active Lease Areas (Geodatabase download link,Shapefile download link, Metadata)
- Anchorage Areas (Metadata)
- BOEM Lease Blocks (Metadata)
- Lightering Zones (Metadata, more information) - Pipelines (Option page, Metadata)
- Shipping Lanes (Federal)
- Unexploded ordnances (Points and areas, metadata)
- BOEM Drilling Platforms (Metadata, Mapping Page, Alternative Platform Structure dataset)
While most data used in the model received a single value, some ranged between 0 and 1. This caused at times a hex cells across the call areas to have more than a single value due to data not sharing the exact same shape and size as the call are hex cells. When this occurred, the analysis chose the minimum value occurring in the hex cell. The minimum value prioritized conservation.
The hexagonal grid in R is slightly different than a tessellation grid that ArcGIS Pro generates in its data management toolbox. This is likely due to differences in the number of significant digits used for the calculations and converting acres into meters.
Hexagon nodes in the grid R creates fall approximately 1.3 meters away from similar nodes for the tessellation generated by ArcGIS. In a 10-acre area, this difference is accounts for 0.64% in distance.
The marine bird data scripts got adapted from Jeffery Leirness's code and previous analysis.
