given a set of lines with starting and ending nodes that form a geometric network, construct an attribute topology.
Usage
make_attribute_topology(x, min_distance)
# S3 method for class 'data.frame'
make_attribute_topology(x, min_distance)
# S3 method for class 'hy'
make_attribute_topology(x, min_distance)Arguments
- x
data.frame network compatible with hydroloom_names.
- min_distance
numeric distance in units compatible with the units of the projection of
lines. If no nodes are found within this distance, no connection will be returned.
Details
If a future plan is set up, node distance calculations will be
applied using future workers.
Examples
x <- sf::read_sf(system.file("extdata/new_hope.gpkg", package = "hydroloom"))
y <- dplyr::select(x, COMID)
y <- sf::st_transform(y, 5070)
z <- make_attribute_topology(y, 10)
x <- add_toids(hy(x), return_dendritic = FALSE)
x[x$id == x$id[1],]$toid
#> [1] 8894334
z[z$COMID == x$id[1],]$toid
#> [1] 8894334
