Is there an Julia function to transform coordinate reference system (e. g. st_transform in R)?

Question

I have an .shp file with ETRS89 / Poland CS92 coordinates and I want to transform it to WGS84[long/lat].
Example of transformation for a point:

ETRS89 / Poland CS92: (184074.7, 682954.7) --> WGS84: (14.18703, 53.91454)

In R it could be done using st_transform function from sf library:

st_transform(polska_grid, "+proj=longlat +ellps=WGS84+datum=WGS84")

Is there function like st_transform in Julia?

Thank you in advance!

There is the reproject function from ArchGDAL that gets further extended by GeoDataFrames. That will offer a similar transform to sf, like so:

import GeoDataFrames as GDF
import GeoFormatTypes as GFT

df = GDF.read("path/to/a.shp")
df.geometry = GDF.reproject(df.geometry, GFT.EPSG(2180), GFT.EPSG(4326))

This example uses GeoDataFrames.jl v0.3.
