Make Geopackage from an dataframe with UTM coordinates

Creates a directory (if it doesn't exist) and writes a layer to a GeoPackage using the name of the input `dat` object as the layer name.

Usage

fpr_make_geopackage(
  dat,
  dir = "data/fishpass_mapping/",
  gpkg_name = "fishpass_mapping",
  ...
)

Arguments

dat

[data.frame] A data frame with coordinates to burn to a GeoPackage.

dir

[character] A string representing the path to the output directory. Default is "data/fishpass_mapping/".

gpkg_name

[character] A string representing the name of the GeoPackage file. Default is "fishpass_mapping".

...

Additional arguments passed to [fpr_sp_assign_sf_from_utm()].

Value

The written GeoPackage layer, invisibly.

Details

This function internally calls [fpr_sp_assign_sf_from_utm()] to convert the input data frame to an [sf::sf] object. You can supply UTM zone and coordinate column names via the `...` arguments: - `col_utm_zone`: A string for the UTM zone column (default is "utm_zone") - `col_easting`: A string for the easting (X) column (e.g., "utm_easting") - `col_northing`: A string for the northing (Y) column (e.g., "utm_northing") - `crs_return`: An integer for the intermediate CRS to assign before transformation

Examples

dat <- data.frame(
  utm_zone = 10,
  utm_easting = c(610000, 611000),
  utm_northing = c(5600000, 5601000)
)
fpr_make_geopackage(
  dat = dat,
  col_easting = "utm_easting",
  col_northing = "utm_northing",
  crs_return = 4326
)
