islandsBuff: Buffer of World Minor Islands

In LimaRAF/plantR: Managing Species Records from Biological Collections

Buffer of World Minor Islands

Description

Map used to support the validation of the original geographical coordinates. It consists in a 0.25 degree buffer (~ 30 km in the Equator) around the minor islands of the world (2 square km or less in size; scalerank >5). All buffers were aggregated and the aggregated buffers were simplified (tolerance 0.01 decimal degrees). Note that buffers were generated at the largest scale available in 'Natural Earth' (i.e. 1:10 m) and simplification was performed after generating and aggregating the buffered polygons.

Usage
