bcmapsdata

Version 0.3.3

img Travis-CI Build Status

This is a package that contains many spatial layers for British Columbia. It is a ‘backend’ data package to provide the layers available in the bcmaps package. We are following the strategy recommended by Anderson and Eddelbuettel.

Installation

Stable version

install.packages('bcmapsdata', repos='https://bcgov.github.io/drat/')

Development version

# install.packages("remotes")
remotes::install_github("bcgov/bcmapsdata")

Legacy version

Older builds of this package were called bcmaps.rdata and will work with bcmaps version <=0.17.1. Those builds can still be installed using:

install.packages('bcmaps.rdata', repos='https://bcgov.github.io/drat/')

Usage

This package is best used in conjunction with the bcmaps. Please follow guidance there.

Adding a new layer

To add a new layer to the package, there are several steps you need to follow:

In the data-raw directory:

  1. Create a new folder to hold the data as downloaded from its source. It is best if the data is available under an open licence such as the Open Government Licence - British Columbia or the Open Government License - Canada. The data should be zipped up in a .zip file to minimize the size. In the directory add a README.md file explaining what the data is and where it comes from, a copy of the licence the data is under, and a .gitignore file that ignores all files except the zip file, the README.md, the licence file, and the .gitignore file.

  2. Create a process_[my_layer].R file in the root of the data-raw directory. Use one of the existing files as a template. It should source("data-raw/utils.R") and use the process_file() function to do the basic processing:

<!-- end list --> 
#' Prepare a spatial file for inclusion in bcmapsdata package
#'
#' @param file path to shp or gdb
#' @param transform transform to BC Albers (default `TRUE`)
#' @param repair Repair toplogy (default `TRUE`)
#' @param filter_stmt An optional filter statement - bare, unquoted. E.g., PRUID == 59
#' @param clip_bc Does it require clipping to BC boundary? Default `FALSE`
#'
#' @return processed sf object
process_file(file, layer, transform = TRUE, repair = TRUE, filter_stmt, 
                         clip_bc = FALSE, crs = NULL)

Use devtools::use_data() to save the processed file in the data directory.

In the R directory:
  1. Create an R file for the documentation of the new layer. Use one of the existing R files as a template.
  2. Run devtools::document()

Commit, push and make a pull request

Optionally add a shortcut function to the frontend bcmaps package:

Install your local updated bcmapsdata package with devtools::install() before moving on to the next steps

In the bcmaps package:

  1. Run devtools::load_all() to load the local version of the package.

  2. Run the internal function bcmaps:::make_shortcuts() while in the bcmaps package directory, then run devtools::document(). This will automatically generate a shortcut function in bcmaps for your new dataset.

  3. Commit your changes and make a pull request to bcmaps.
