In WeiquanLuo/rivertopo: What the Package Does (One Line, Title Case)

rivertopo

The goal of rivertopo is to simplify a given tree topology (ie. for River network) with given locations. For example:

• convert object class rivernetwork from riverdist package to river topology in form of arcs between vertice.

# resulted river topology
data.frame(from = c("Vertex1", "Vertex2"), to = c("Vertex2", "Vertex3"))
#>      from      to
#> 1 Vertex1 Vertex2
#> 2 Vertex2 Vertex3

• convert a list of interesting location points into topological structure by mapping it on a given river topology

# given location point:
data.frame(id = c("Point1", "Point2", "Point3"),
                   lat = c(42.032974, 44.032323, 47.123123),
                   long = c(-93.581543, -92.58345343, -96.2324543),
                   stringsAsFactors = FALSE)
#>       id      lat      long
#> 1 Point1 42.03297 -93.58154
#> 2 Point2 44.03232 -92.58345
#> 3 Point3 47.12312 -96.23245

# resulted location topology:
data.frame(from = c("Point1", "Point2"), to = c("Point2", "Point3"))
#>     from     to
#> 1 Point1 Point2
#> 2 Point2 Point3
