Example origin and target site positions and distances on a 2-D plane

Description

sampleOriginPos is a dataset containing example origin site positions from 12 scenarios used in Cohen et al. (2018). For the same 12 scenarios, sampleOriginDist contains the origin site distances, sampleTargetPos contains the target site positions, and sampleTargetDist contains the target site distances.

Usage

sampleOriginPos

sampleOriginDist

sampleTargetPos

sampleTargetDist

Format

Each dataset is a named list with 12 matrices in it, representing 12 scenarios. The position matrices each have 2 columns (x and y position) and 4 rows (for each origin or target site). The distance matrices are symmetrical and 4 x 4. The 12 scenarios are:

Linear: Both origin and target sites arranged in horizontal linear fashion, with equal distances between each adjacent site
B Dist BC*2: Linear, but the central origin sites are twice as far from each other as the edge sites are from the adjacent origin sites
B Dist BC/2: Linear, but the central origin sites are half as far from each other as the edge sites are from the adjacent origin sites
B Dist CD*2: Linear, but the last two origin sites are twice as far from each other as the other adjacent origin sites
B Dist CD/2: Linear, but the last two origin sites are half as far from each other as the other adjacent origin sites
B Grid: Origin sites arranged on a grid, target sites arranged linearly, both with all adjacent sites (excluding diagonals) equidistant
NB Dist 23*2: Linear, but the central target sites are twice as far from each other as the edge sites are from the adjacent target sites
NB Dist 23/2: Linear, but the central target sites are half as far from each other as the edge sites are from the adjacent target sites
NB Dist 34*2: Linear, but the last two target sites are twice as far from each other as the other adjacent target sites
NB Dist 34/2: Linear, but the last two target sites are half as far from each other as the other adjacent target sites
NB Grid: Target sites arranged on a grid, origin sites arranged linearly, both with all adjacent sites (excluding diagonals) equidistant
B/NB Grid: Origin and target sites each arranged on a grid, both with all adjacent sites (excluding diagonals) equidistant
