GPDI543 - Introduction to Spatial data in R

Geographic Information Systems are increasingly being applied in multiple settings including research, decision-making and education. Examples include mapping research participant addresses in order to locate distance to the nearest park or calculating the population density within a 100 km radius of a hospital. R is a great tool for spatial data manipulation as it is free and easy to use and can perform a large number of functions. This session will provide a brief introduction to spatial data manipulation in R to orient participants so they can go on and carry out more complex tasks.

The following topics will be covered:
- Importing and mapping tabular data
- Introduction to geographic and projected coordinate systems
- Introduction to spatial, topological and attribute operations

Participants must have a working knowledge of R and will need to bring their own laptop with R (version 3.4 or above) and Rstudio installed. To learn how to install R and RStudio, please use the
following resources:
Mac OS:
We will be also be using several R packages including dplyr, rgdal, sp, sf, rgdal and magrittr.
Here is a quick guide on how to install an R package:

Learning Objectives

In this workshop participants will:
1. Understand what projection means in the context of geographic data
2. Know the different types of spatial data
3. Retrieve a list of geographic and projected coordinate systems
4. Import tabular data and convert to a map
5. Plot maps and sections of maps
6. Subset spatial data: by attributes or spatial overlap

Leaders Information

This workshop is led by Yara Abu Awad, ScD, a Harvard University trained epidemiologist with expertise analyzing big data by applying causal inference methods and machine learning techniques using R. She is currently at the Department of Psychology investigating the impact of stress on obesity among children, the impact of parental expectations on children’s sleep quality and the impact of social inequalities on children’s health.

This workshop is not scheduled at this time.
