pdxTrees
A Data Package composed of information for all the inventoried trees in
Portland, Or. There are three datasets in the package, pdxTrees_parks,
which contains data on 25534 trees,ohsuTrees_parks, which contains
data on 875 trees in the parks surrounding the Oregon Health and Science
University, and pdxTrees_streets, which contains data on 218,602 trees
located on Portland’s streets. A street tree is losely defined as a tree
generally in the public right-of-way, usually between the sidewalk and
the street. Street trees are categorized by one of the 96 Portland
neighborhoods and the park trees are categorized by the public parks in
which they grow.
These data were collected by the Portland Parks and Recreation’s Urban
Forestry Tree Inventory Project. The Tree Inventory Project has gathered
data on Portland trees since 2010, collecting this data in the summer
months with a team of over 1,300 volunteers and Forestry employees. The
streets trees were inventoried from 2010 to 2016, and the park trees
that currently make up pdxTrees_parks and ohsuTrees_parks, were
invetoried from 2017 to 2019. More information on the data can be found
here.
pdxTrees is used in multiple Reed College statistics courses as a tool
to help students learn and become more comfortable with the
functionalities of RStudio. In Intro to Probablity and Statistics,
pdxTrees is used to learn the components of graphics, wrangle data
with dplyr, and create graphs with ggplot2. In the Data Science
course, the package is used to teach the best practices of function
writting, construct interactive maps with leaflet, and showcase the
usefulness of lubridate along with many other R packages.
