Figure 4From: Estimating spatial accessibility to facilities on the regional scale: an extended commuting-based interaction potential modelMaps of number of grocery stores (left) and potential accessibility surface (right). These maps show the distribution of grocery stores by municipality (left) and smoothed surface of potential accessibility (right). Potential accessibility was estimated with an exponential-shaped function and a 14 km span. Class limits were defined manually for visualisation and comparison purposes.Back to article page
