PRU Atlas

This is still Work In Progress but we value constructive feedback: please check the issues page and eventually file a bug or a feature request.

The pruatlas package provides helpers for generating maps of interest for PRU publications.

There are both high and low level facilities. For an example of a high level helper, the code for plotting a map of the Germany country FIR and ANSP is as follows:

library(sf)
library(pruatlas)
fl <- 300
plot_country_fir("ED", "Germany", fl = fl)
plot_country_ansp("DFS", "DFS, Germany", fl = fl)

Or EUROCONTROL’s Member States FIR area:

ms <- "BI|E.|L.|UD|UG|GM|UK|GC"
plot_country_fir(icao_id = ms, "EUROCONTROL Member States", buffer = 350, fl = 200)

Lower level functions or datasets include for example countries50m, the Simple Feature for the whole world countries or extent_fir() to calculate the bounding box of a country FIR.

Useful functions are:

• plot_country_fir()
• plot_country_ansp()

The package contains the following aviation GIS datasets (for CFMU AIRAC 406, see below):

• firs_nm_406: the FIR’s as defined/used by EUROCONTROL’s Network Manager
• ansps_ace_406: the ANSP’s as defined/used in ACE Benchmarking Report

(CFMU) AIRAC 406, a.k.a. AIRAC 1512, spans the 28-day interval 2015-11-12 UTC–2015-12-10 UTC.

If you need polygons in different AIRAC’s that the one in the package and have access to EUROCONTROL DB, you can have a look at the scripts in the data-raw directory. For example export_nm_fir_geojson.R or export_ace_ansp_geojson.R allow for exporting FIR’s or ANSP’s to GeoJSON which can be read as {sf} features via sf::read_sf().

Installation

Pruatlas is still in early development and it is only available on GitHub. It relies and uses the functionality from the sf package and this relies on a working installation of GDAL, see the sf installation instructions for directions.

In order to install pruatlas you need to run:

library(remotes)
install_github("euctrl-pru/pruatlas")

To Do’s

• implement similar facilities as FIR’s/ANSP’s for Elementaty Sectors (ES’s) in order to be able to plot single ES or ACC’s
• include export_<airspace_type> in the package API rather than as scripts for the package datasets
• extract style from plot functions and make it a better theme
• extend Member States dataset

Development

In order to build the relevant pkgdown web pages, execute the following code:

# How to build the pkgdown from behind proxied Internet
library(withr)
library(pkgdown)

with_options(list(pkgdown.internet = FALSE),
             build_site())
