Karl Miller Center, 615 SW Harrison Street, Portland, OR
Room KMC TBD
In this workshop, you will build on existing knowledge of GIS and mapping in R to tackle more advanced problems, including raster and geospatial feature analysis and the creation of interactive web maps using leaflet. Topics include using terra to analyze raster data (e.g., time series, spatial pattern analyses, point extraction, and spatial statistics) and using sf to join and analyze vector data. Both raster and vector datasets will be incorporated into leaflet maps to visualize different types of geographic information based on their underlying data structures.
Knowledge Prerequisites: A basic understanding of the terra and sf packages is recommended.
Pre-Installations: A recent version of R and RStudio and the following packages: dplyr, ggplot2, patchwork, viridis, knitr, terra, sf, Kendall, leaflet, leaflet.extras, usaboundaries, httr
