urbioconnect: Urban Habitat Connectivity Analysis

Analyse and visualise habitat connectivity in urban landscapes, accounting for barriers and buffer distances. Includes Shiny app for interactive analysis and report generation. Based on methods developed by Kirk et al (2023) <doi:10.1016/j.mex.2022.101989>.

Getting started
Overview | The example data | The pipeline, step-by-step | Step 1: Create the barrier mask | Step 2: Remove habitat under barriers | Step 3: Buffer the habitat | Step 4: Fragment habitat along barriers | Step 5: Assign patch IDs | Step 6: Summarise patch areas | Computing connectivity metrics | Run the pipeline as a single step | Comparing multiple interpatch distances | Summary

Using urbioconnect in a targets pipeline
Why use targets for connectivity analysis? | A minimal _targets.R | What each section does | Running and inspecting the pipeline | Running | Inspecting results | Visualising the dependency graph | Example workflows

Interpatch distance and raster resolution
Interpatch distance | Buffering happens on a grid | A sub-cell radius does nothing - and habitat_buffer() warns | Why it matters: the same distance, two resolutions | Choosing a resolution | What about vector (sf) data?
