In uribo/jpmesh: Utilities for Japanese Mesh Code

Convert from coordinate to mesh code

Description

From coordinate to mesh codes.

Usage

coords_to_mesh(longitude, latitude, to_mesh_size = 1, geometry = NULL, ...)

Arguments

longitude	longitude that approximately to .120.0 to 154.0 (double)
latitude	latitude that approximately to 20.0 to 46.0 (double)
to_mesh_size	target mesh size. That is, 1 for 1km, and 0.5 for 500m. From 80km to 0.100km.
geometry	XY sfg object
...	other parameters

Value

mesh code (default 3rd meshcode aka 1km mesh)
