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

Convert a LAGOSNE 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 = "nhd_lat", longname = "nhd_long", crs = 4326)

Arguments

dt	data.frame
latname	character name of latitude column; default is "nhd_lat"
longname	character name of longitude column; default is "nhd_long"
crs	numeric epsg code; default is 4326 WGS84-lat-long

Examples

## Not run: 
dt <- lagosne_load("1.087.3")
res <- coordinatize(dt$locus)

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)
