coordinatize: Convert a LAGOSUS flat file into a spatial object

In cont-limno/LAGOSUS: Interface to the Lake Multi-Scaled Geospatial and Temporal Database

Convert a LAGOSUS flat file into a spatial object

Description

This function turns a data.frame into a spatial object using a reasonable default projection.

Usage

coordinatize(
  dt,
  latname = "lake_lat_decdeg",
  longname = "lake_lon_decdeg",
  crs_in = 4326,
  crs_out = albers_conic()
)

Arguments

dt	data.frame
latname	character name of latitude column; default is "lake_lat_decdeg"
longname	character name of longitude column; default is "lake_lon_decdeg"
crs_in	numeric epsg code; default is 4326 WGS84-lat-long
crs_out	numeric epsg code; default is albers_conic

Examples

## Not run: 
dt <- lagosus_load("locus")
res <- coordinatize(dt$locus$lake_information)

library(maps)
map("state", xlim = c(-97.90363, -66.99892), ylim = c(34.61761, 49.41941))
plot(res$geometry, add = TRUE, pch = 19, cex = 0.05)

## End(Not run)
