Floating Catchment Area (FCA) Methods to Calculate Spatial Accessibility R package fca version 0.1.0 Perform various floating catchment area methods to calculate a spatial accessibility index (SPAI) for demand point data. The distance matrix used for weighting is normalized in a preprocessing step using common functions (gaussian, gravity, exponential or logistic).
