In mdlincoln/bigosm: Read Large OSM Exports

bigosm

bigosm reads in particularly large OSM XML exports (>400MB) that cause osmar's XML reader to choke.

Installation

You can install the development version of bigosm from GitHub with:

# install.packages("devtools")
install_github("cmu-lib/bigosm")

Usage

read_big_osm does what it says on the label. By specifying required keys for both Ways and Relations you can pre-filter the XML that ends up getting pulled into R.

library(bigosm)
library(osmar)

boston_xml <- system.file("extdata/boston.xml.zip", package = "bigosm")

boston_osm <- read_big_osm(file = boston_xml, way_keys = "highway")

summary(boston_osm)

Context

This package is one of several originally developed by Matthew Lincoln for use by Carnegie Mellon University's "Bridges of Pittsburgh" project:

• konigsberger (end-user package)
• pathfinder
• bigosm
• simplygraph
