River Meuse outline

The meuse.riv data consists of an outline of the Meuse river in the area a few kilometers around the meuse data set.

The meuse.area polygon has an outline of meuse.grid. See example below how it can be created from meuse.grid.

data(meuse.riv)
data(meuse.area)

Format

meuse.riv: two-column data.frame containing 176 coordinates.

meuse.area: two-column matrix with coordinates of outline.

Details

x and y are in RDM, the Dutch topographical map coordinate system. See examples of spTransform for projection parameters.
