rhineCCM2: CCM2 River and Catchment of the Rhine Catchment, Rivers only

Description

This spatial dataset is a subset of the data layer RIVERSEGMENTS of the tile WGS84_W2003 from the CCM River and Catchment Database v2.1 (Vogt et al. 2007). The original data format was PGeo (ESRI Personal GeoDatabase). The subset consists of rivers within the Rhine basin, i.e. WSO_ID = 291110. In order to save disk space, the fields of the attribute table were shortened.

Format

An Object of class SpatialLinesDataFrame with 30343 features. The attribute table comprises 2 fields:

WSO1_ID

int, unique river segment identifier

PFAFSTETTER

num, Pfafstetter code according to CCM2

The PROJ.4 string is +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0.

Examples

if (FALSE) {
## get the flowpath from a head catchment to
## the sea
## Be patient, this might take a while.
system.time(fps <- 973842223 %up% rhineCCM2$PFAFSTETTER)
flowpath <- subset(rhineCCM2, subset = fps)
sp::plot(flowpath)

## does parallel threats increase the speed
## and provide the same results?
op.old <- options()
options("hydrocode.parallel" = TRUE)
system.time(fpp <- 973842223 %up% rhineCCM2$PFAFSTETTER)
all.equal(fps, fpp)

## reset previous settings
options(op.old)
