Prediction sites for heavy metals in mosses near a mining road in Alaska, USA

Description

Prediction sites for heavy metal concentrations in mosses near a mining road in Alaska, USA with object type SpatialPointsDataFrame from sp package. Data on covariates used to model observed data are included with site location.

Usage

data(MOSSpreds)

Format

A sf object. The projection is in Alaska Albers, EPSG:3338. The dataframe has 2357 observations and 5 variables.

lon

Longitude, in decimal degrees

lat

Latitude, in decimal degrees

dist2road

Distance to haul road, in meters

sideroad

A factor variable with two levels: "N" for north of the haul road, and "S" for south of the haul road

strat

A stratification variable for prediction sites, in distance classes from the haul road, where 1 is the closest, and 5 is the farthest, from the road

Source

This prediction grid was provided by Peter Neitlich and used in the publication given below.

Imported to R with the rgdal package as a SpatialPoints object from package sp. The code that creates the data file from the raw data can be found at system.file("raw data/MOSSHeavyMetals/create_MOSSpreds.R",package = "ZVHdata"). It was subsequently converted to sf using st_as_sf function.
