BUFFER INACCURACIES
Does anyone know why buffers become increasingly more inaccurate on certain
bearings above distances of 4000+ Nautical Miles??
eg. For buffers centred on the UK, the buffer distances are correctly
measured to the South (to South Africa), West(the USA) & East(to Russia) ie.
on lines of longitude and latitude passing through the buffer's origin.
Sections of buffers to the South West (South America) & South East
(Indonesia) & presumable to the NE & NW become increasingly more inaccurate
with distance from the origin (UK).
Tracing around the buffer's perimeter with the RULER tool (which correctly
measures the distance) centred on the UK shows the extent of the inaccuracy
along the a 4000Nmile buffer which can be up to 500 Nmiles out!,
thanks in anticipation,
