make_global_grid

Use this function to create a regular grid in a custom CRS. This is used
e.g. to create the tile grid for Global Forest Watch in order to retrieve
the intersecting tiles with a given portfolio.

Biodiversity areas, especially primary forest, serve a
multitude of functions for local economy, regional functionality of
the ecosystems as well as the global health of our planet. Recently,
adverse changes in human land use practices and climatic responses to
increased greenhouse gas emissions, put these biodiversity areas under
a variety of different threats. The present package helps to analyse a
number of biodiversity indicators based on freely available
geographical datasets. It supports computational efficient routines
that allow the analysis of potentially global biodiversity portfolios.
The primary use case of the package is to support evidence based
reporting of an organization's effort to protect biodiversity areas
under threat and to identify regions were intervention is most duly
needed.
