Introduction to Open Source GIS for ArcGIS Users CLASS SESSIONS Monday, June 24 – 28, 2019 8:30am – 12:30 pm Location: TBD Directions can be found here: http://www.cuepisummer.org/contactpage INSTRUCTORS: Philip M. Hurvitz, PhD Research Associate Professor [email protected] | http://gis.washington.edu/phurvitz COURSE DESCRIPTION Although popular desktop geographic information systems (GIS) packages are commonly used for processing spatial data and generating results in epidemiology and public health, work flows are typically undocumentable, which poses a major problem for transparency and reproducibility. This course will introduce the use of three main open source GIS tools with particular emphasis on scripting for documenting research processes. • The open source GIS software PostGIS is the spatial data management and analysis extension for the powerful open source relational database application, PostgreSQL. We will cover installation and configuration of PostgreSQL and PostGIS, data creation/conversion/export, management, and analysis. • The desktop GIS application QGIS will be used for display and map production. • The open source statistical programming application R/Rstudio will be used with the Simple Features (sf) package, which implements GIS operations within the R framework. Rmarkdown will be used for generating research documentation including embedded “slippy” maps with the Leaflet package. COURSE OBJECTIVES By the end of the course students will be able to: • Install and configure PostgreSQL and PostGIS Specific instructions for installing on Windows will be provided in the course package; other installations will be covered as necessary • Manage spatial data sets in the database • Perform spatial analyses using spatial SQL statements with PostGIS • Perform spatial analysis using simple features in R • Generate summary data based on spatial operations with particular attention to public health and epidemiology applications • Use QGIS for display and map production • Use R and RStudio for creating reports with map, graphical, and tabular output from spatial operations PREREQUISITES Hardware: Students will need a laptop (Windows, Mac, or Linux) running a recent OS release, and with administrator-level access. Skills: Students should have beginning to intermediate experience • Using ArcGIS Desktop • Using a shell (e.g., DOS command prompt for Windows, terminal for Mac or Linux) COURSE READINGS • PostgreSQL Manual • PostGIS Manual • Simple features for R • Hurvitz, P.

He has over 20 years of combined GIS teaching and research experience. He has taught GIS at the undergraduate and graduate levels, and has run over a dozen hands-on GIS workshops focusing on fast-tracking practical GIS skills. His work currently focuses on the relationship between the composition and configuration of the built environment on health-related behaviors. This new course will focus on technical issues at the nexus of public health/epidemiology and urban planning. .
