geo_projected: Perform GIS functions on a temporary, projected version of a spatial object

Description

This function performs operations on projected data.

Usage

geo_projected(shp, fun, crs, silent, ...)

Arguments

shp

A spatial object with a geographic (WGS84) coordinate system

fun

A function to perform on the projected object (e.g. the the rgeos or sf packages)

crs

An optional coordinate reference system (if not provided it is set automatically by geo_select_aeq())

silent

A binary value for printing the CRS details (default: TRUE)

...

Arguments to pass to fun, e.g. byid = TRUE if the function is rgeos::gLength()))

Examples

# NOT RUN {
shp <- routes_fast_sf[2:4, ]
plot(geo_projected(shp, sf::st_buffer, dist = 100)$geometry)
shp <- routes_fast[2:4, ]
geo_projected(shp, fun = rgeos::gBuffer, width = 100, byid = TRUE)
rlength <- geo_projected(routes_fast, fun = rgeos::gLength, byid = TRUE)
plot(routes_fast$length, rlength)
# }
