emodnetbiologymaps's Introduction

EMODnetBiologyMaps

The goal of EMODnetBiologyMaps is to create ggplot2 maps of using the EMODnet style:

Colors follow the EMODnet guidelines
The default projection is EPGS:3035: ETRS89-extended / LAEA Europe
When the map is saved as .png, the EMODnet logo is pasted in the final map.

Installation

You can install the development version of EMODnetBiologyMaps with:

devtools::install_github("EMODnet/EMODnetBiologyMaps")

Example

Export a gridded abundance map of anchovies (Engraulis encrasicolus):

# devtools::install_github("lifewatch/eurobis")
library(EMODnetBiologyMaps)
library(eurobis)

# Retrieve grid data for "Eriocheir sinensis" (AphiaID = 126426) using the eurobis package
points <- getEurobisGrid(aphiaid = 126426, gridsize = '1d')

# Render ggplot2 map
map <- emodnet_map_plot(points, fill = points$RecordCount,  title = "Engraulis encrasicolus", subtitle = "AphiaID 126426", legend = "Abundance", zoom = FALSE, option = "viridis")

# Save with EMODnet logo
emodnet_map_logo(map, path = "./data-raw/map1.png", width = 198, height = 121, dpi = 300, units = "mm", gravity = "northeast", offset = "+650+200", color = TRUE)

emodnetbiologymaps's Issues

Dependency on eurobis not needed

As described in #1 , the dependency on the eurobis and therefore on imis packages difficults the installation of the EMODnetBiologyMaps package.

This can by solved by removing the packages from Imports and add to Suggests. With usethis::use_dev_package("package", type = ""Suggests) these are added also to the Remotes section of the DESCRIPTION file.

Potential enhancements

This issue documents the feedback received about the package.

Last update 2020-10-02:

Eurobis package difficults installation. This package is only used for the examples and tests, not needed.

Determine best width and height when printing to .png

Border of rasters are drawn. Include option 'color=NA’ in the ggplot2 command.

Restrict to emodnet colors?

Adjust EMODnet logo

Include all the IHO areas that we’re using for the reporting

Include a standard legend stating that the data are from EMODnet

Extent of the map should be focused on reporting areas.
