swfscAirDAS
This package contains functions designed for processing and analyzing
aerial survey DAS data (AirDAS) generated by the Southwest Fisheries
Science Center using one of the following programs: PHOCOENA, CARETTA,
or TURTLE (such as TURTLEP or TURTLE4D). Functionality includes reading
AirDAS data into a data frame, processing this data (extracting state
and condition information for each AirDAS event), and summarizing
sighting and effort information. Plans for future development include:
generating tables summarizing the information in the AirDAS file,
plotting AirDAS data, and generating files needed for doing density
estimation. Learn more in vignette("swfscAirDAS")
Installation
You can install the released version of swfscAirDAS from CRAN with:
install.packages("swfscAirDAS")You can install the developmental version of swfscAirDAS from GitHub. To use the development version of swfscAirDAS, it is recommended to install the development version of swfscDAS as well:
# install.packages("remotes")
remotes::install_github("smwoodman/swfscDAS", build_vignettes = TRUE)
remotes::install_github("smwoodman/swfscAirDAS", build_vignettes = TRUE)Please contact the developer if you have any issues.
AirDAS format and checks
swfscAirDAS accepts AirDAS data from several different programs, and thus in several different formats: PHOCOENA, CARETTA, and TURTLE. You can download PDFs describing these formats at the following links:
These PDFs are also included in the package; see
airdas_format_pdf
for more details.
In addition, the package contains the function
airdas_check,
which checks whether the provided file adheres to expected format of the
provided file type. This function is designed to 1) be used for data
QA/QC after performing a survey and 2) ensure the data format meets all
of the assumptions made by the rest of the functions in the package. A
PDF describing the format checks is included in the package; you can
