In tfullman/dia: Monte Carlo Development Simulation and Wildlife Impacts Analysis

Summarize simulated infrastructure

Description

Infrastructure summary analysis. This calculates the number of facilities/length of roads, area of direct surface disturbance, and area within 4 km of infrastructure for comarison with statistics provided by the Bureau of Land Management (BLM) in the Integrated Activity Plan Draft Environmental Impact Statement (IAP DEIS) for the National Petroleum Reserve - Alaska (NPR-A) (BLM 2019a). These metrics are added to the out.df data.frame.

Usage

inf_summary(
  out.df,
  cpf.spdf,
  sat.spdf,
  rd.sl,
  surf.disturb,
  npra.file,
  zoi = 4000,
  wd.loc,
  path.in
)

Arguments

out.df	data.frame object containing the current scenario and iteration information. Created during the impact analysis by dia.
cpf.spdf	SpatialPointsDataFrame object indicating central processing facility (CPF) locations. Created by generate_cpf.
sat.spdf	SpatialPointsDataFrame object indicating satellite production facility locations. Created by generate_sat_rd.
rd.sl	SpatialLines object indicating gravel road centerlines. Created by generate_sat_rd.
surf.disturb	SpatialPolygonsDataFrame object representing the combined footprint of central processing facilities (CPFs), satellite pads, and roads. Created by footprint_generation.
npra.file	Character string giving the file name of the NPR-A boundary shapefile, without extension.
zoi	Numeric value indicating the zone of influence (m) in which habitat quality is discounted. Defaults to 4000 m, as is used in BLM (2019a).
wd.loc	Character string identifying the base directory containing both input and output data folders.
path.in	Character string identifying the relative path from the base directory (wd.loc) to where input data are stored.

Value

out.df data.frame, updated to contain the infrastructure summary results.
