Lambert Azimuthal Equal-Area (LAEA) projection centered on the Azores

Description

laea_azores_proj() creates a PROJ string for a custom Lambert Azimuthal Equal-Area (LAEA) projection, centered on the Azores. It allows flexibility in setting the latitude and longitude center, datum, and units.

Usage

laea_azores_proj(lat_0 = 38.5, lon_0 = -28, datum = "WGS84", units = "m")

Arguments

lat_0	Numeric. Latitude of the projection's center. Defaults to 38.5 (Central Azores).
lon_0	Numeric. Longitude of the projection's center. Defaults to -28 (Central Azores).
datum	Character. The geodetic datum used for the projection. Defaults to "WGS84". Other options include "ETRS89", "NAD83", etc.
units	Character. Measurement units for the projection. Defaults to "m" (meters). Can be set to "ft" (feet) if needed.

Value

A character string representing the PROJ definition for the custom LAEA projection.

Examples

# Default Azores-centered LAEA projection
laea_azores_proj()

# Custom projection centered at a different location
laea_azores_proj(lat_0 = 38, lon_0 = -27, datum = "ETRS89")
