What is Geospatial Analysis?
Geospatial analysis involves collecting, analyzing, and interpreting data tied to geographic locations and the characteristics of physical features or phenomena on Earth’s surface. It leverages spatial information—such as coordinates, maps, or geospatial data layers—to uncover patterns, relationships, and insights that may not be apparent in non-spatial data.
This approach is particularly valuable in fields like epidemiology, where it helps identify hotspots and high-risk areas for the spread of communicable diseases.
Why Use R for Geospatial Work?
R is a powerful tool for geospatial analysis, offering several advantages:
Reproducibility: R allows you to automate workflows and share reproducible code for consistent results.
Reporting: With packages like rmarkdown, R makes it easy to integrate analysis, visualization, and reporting in a seamless document.
Rich Ecosystem: R provides a vast collection of geospatial packages, such as sf, raster, and leaflet, to handle data wrangling, visualization, and analysis.
Convenience: R’s syntax and tools simplify complex geospatial tasks, from mapping to statistical modeling.
Integrated Workflow: R enables users to combine geospatial visualization and statistical analysis in a single script, streamlining the analytical process.
By leveraging R’s capabilities, geospatial analysts can efficiently handle complex spatial datasets and deliver actionable insights.
