New Zealand Spatial Features (nzsf) is an R package for creating scientific maps in New Zealand waters. The nzsf package relies heavily on the R packages ggplot2, dplyr, and sf providing a straightforward approach for complex mapping tasks. Maps can be built up in layers in the same way as ggplot2 so users can easily add points, lines/arrows, polygons, coastlines, and much more.
Installation
The nzsf package can be installed from within R using:
library(devtools)
install_github(repo = "ropensci/rnaturalearthhires")
install_github(repo = "quantifish/nzsf", build_vignettes = TRUE)In the future I hope to release nzsf as a formal R package on The Comprehensive R Archive Network (CRAN).
Help
The package vignettes are a great place to see what nzsf can do. You can view the package vignettes from within R using:
browseVignettes(package = "nzsf")
vignette(topic = "nzsf", package = "nzsf")Alternatively, you can look at the help pages associated with each function and data set in nzsf. To see them all use:
help(package = "nzsf")Shapefiles
The nzsf package includes many different shapefiles including New Zealand Quota Management Area (QMA) boundaries for many finfish and shellfish stocks including:
| Species code | Common name | Scientific name | Maori name |
|---|---|---|---|
| COC | Cockle | Austrovenus stutchburyi | Tuangi |
| CRA | Red rock lobster | Jasus edwardsii | Kōura |
| HAK | Hake | Merluccius australis | Kehe, tiikati |
| HOK | Hoki | Macruronus novaezelandiae | Hoki |
| LIN | Ling | Genypterus blacodes | Hoka, hokarari, rari |
| OEO | Oreo | ||
| ORH | Orange roughy | Hoplostethus atlanticus | Nihorota |
| PAU | Paua | Haliotis iris | Pāua |
| PHC | Packhorse rock lobster | Sagmariasus verreauxi | Kōura Papatia |
| PPI | Pipi | Paphies australis | Pipi |
| SWA | Silver warehou | Seriolella punctata | Warehou hiriwa |
| SBW | Southern blue whiting | Micromesistius australis | |
| SCA | Scallop | Pecten novaezealandiae | Tupa |
Other useful shapefiles include:
- The New Zealand coastline (in high, medium, and low resolution)
- Depth contours (in high, medium, and low resolution)
- New Zealands Exclusive Economic Zone (EEZ)
- Department of Conservation (DOC) marine reserves
- Rock lobster statistical areas
- New Zealand rocky reefs
- Te Tapuwae o Rongokako (Gisborne) habitats and reefs
These shapefiles can be accessed using the data command in R. For example:
data("doc_marine_reserves")If you would like additional shapefiles added just let me know in the issues (please include a link to the shapefiles).
