In USFWS/AKaerial: Analysis of Alaska Region Aerial Survey Data

Summarize design transects for analysis using sf package

Description

TransSummarySF will provide the overall design transect spatial characteristics for analysis

Usage

TransSummarySF(
  transect.file,
  transect.layer,
  strata.file,
  trans.id = "OBJECTID",
  strata.id = "STRATNAME",
  current = "Transect"
)

Arguments

transect.file	The path to the design stratification file
transect.layer	The name of the design transect layer in the geopackage
strata.file	The path to the analysis stratification layer
trans.id	The identifier of the correct transect numbering
strata.id	The identifier of the stratification layer
current	The identifier of the current navigational transect

Details

TransSummarySF will compute sampled lengths (in km) and areas of each transect (in km^2) in a design transect file

Value

data frame summary of sampled transects
