Description

boundary_segments_25N() returns the boundary segments in the meter-based projection PTRA08 / UTM zone 25N, i.e. those boundary segments in the western-most part of the archipelago: Ilha das Flores and Ilha do Corvo.

boundary_segments_26N() returns the boundary segments in the meter-based projection PTRA08 / UTM zone 26N, i.e. those boundary segments in the Central and Eastern groups of the archipelago.

Usage

boundary_segments(crs = laea_azores_proj())
boundary_segments_25N()
boundary_segments_26N()
