view_crs: Quickly preview the extent of a given CRS using mapview

In crsuggest: Obtain Suggested Coordinate Reference System Information for Spatial Data

Quickly preview the extent of a given CRS using mapview

Description

The crsuggest package makes coordinate reference systems suggestions that may not be perfect for your specific analytic use case. Use view_crs() to quickly view the geographic extent of a given coordinate reference system (represented by its EPSG code) and assess whether that CRS makes sense for your data.

Usage

view_crs(crs)

Arguments

crs	A character string representing the EPSG code of an input coordinate reference system, possibly returned by suggest_top_crs.

Value

an object of class mapview which uses the mapview package to preview the extent of a coordinate reference system.

library(tigris)
library(crsuggest)
options(tigris_use_cache = TRUE)

# Get a Census tract dataset from the tigris package
tarrant_tracts <- tracts("TX", "Tarrant", cb = TRUE, year = 2021)

# Suggest a CRS for your data
target_crs <- suggest_top_crs(tarrant_tracts, units = "m", inherit_gcs = FALSE)

# Preview the extent of the CRS
view_crs(target_crs)
