gsection: Function to split overlapping SpatialLines into segments

Description

Divides SpatialLinesDataFrame objects into separate Lines. Each new Lines object is the aggregate of a single number of aggregated lines.

Usage

gsection(sl, buff_dist = 0)

Arguments

sl

SpatialLinesDataFrame with overlapping Lines to split by number of overlapping features.

buff_dist

A number specifying the distance in meters of the buffer to be used to crop lines before running the operation. If the distance is zero (the default) touching but non-overlapping lines may be aggregated.

Examples

# NOT RUN {

rsec <- gsection(sl)
rsec_buff <- gsection(sl, buff_dist = 1)
plot(sl[1], lwd = 9, col = 1:nrow(sl))
plot(rsec, col = 5 + (1:length(rsec)), add = TRUE, lwd = 3)
plot(rsec_buff, col = 5 + (1:length(rsec_buff)), add = TRUE, lwd = 3)
# }
# NOT RUN {
sl <- routes_fast_sf[2:4, ]
rsec <- gsection(sl)
rsec <- gsection(sl, buff_dist = 100) # 4 features: issue
