Prediction Grid for Meuse Data Set

Description

The meuse.grid data frame has 3103 rows and 7 columns; a grid with 40 m x 40 m spacing that covers the Meuse study area (see meuse)

Usage

data(meuse.grid)

Format

This data frame contains the following columns:

x

a numeric vector; x-coordinate (see meuse)

y

a numeric vector; y-coordinate (see meuse)

dist

distance to the Meuse river; obtained by a spread (spatial distance) GIS operation, from border of river; normalized to $[0,1]$

ffreq

flooding frequency class, for definitions see this item in meuse; it is not known how this map was generated

part.a

arbitrary division of the area in two areas, a and b

part.b

see part.a

soil

soil type, for definitions see this item in meuse; it is questionable whether these data come from a real soil map, they do not match the published 1:50 000 map

Details

x and y are in RD New, the Dutch topographical map coordinate system. Roger Bivand projected this to UTM in the R-Grass interface package.
