each pair of from
and to
points. Thanks to

.dodgr_dists()

download street networks, thus former parameters wt_profile

.weight_railway
to weight a network for
railway routing.dodgr_dists
implements Dijkstra paths with std::set
sorting through new option dodgr_dists(..., heap = "set")
(It’s slower than others, but good for sake of completeness).dodgr_streetnet
now accepts polygonal bbox
argument, and uses osmdata::trim_osmdata
to trim resultant
network to within that polygon (issue #50).weight_streetnet
and
dodgr_flows_aggregateto include a non-OSM example from
stplanr::routes_fast`
(issue #45).dodgr_dist
calculations wrong (Earth’s radius is 6371, not 3671!) - thanks to @chrijoweight_streetnet
function now accepts

objects defining wt_profile
,
enabling modification and direct re-submission of
dodgr::weighting_profiles

modified to 0-1 scores rather
than previous percentage values.weight_streetnet
flags any highway types not present in
nominated or submitted weighting profile.dodgr_paths
now has additional pairwise
parameter to enable paths only between matched pairs of
from
and to
points (so returning
n
paths rather than n^2
), thanks to @mem48.dodgr_to_sf
deprecated to dodgr_to_sfc
(#43)dodgr_paths
and simple
data.frame
s, thanks to James Smith.match_pts_to_graph
has additional
connected
parameter to allow points to be matched only to
largest connected component.dodgr_flowmap
plots maps of flows.
Currently only writes .png files, because large networks can not be
effectively plotted on graphic devices.dodgr_flows
has option to routes flows from a set of
source origins to all points in a network, attenuated by distance from
those origins.dodgr_to_sf
converts a spatially-explicit
dodgr
graph into Simple Features (sf
)
format.match_pts_to_graph
now accepts Simple Features (sf)
collections of sfc_POINT
objects to be matched.Tidy C++ code that flagged errors on CRAN solaris machine. Nothing else.
dodgr_paths
, for returning explicit
shortest path routes.dodgr_flows
, for aggregting flows across
a network from multiple origin and destination points.merge_directed_flows
, to reduce
aggregated directional flows to non-directional equivalent values useful
for visualisation.weight_streetnet
now accepts arbitrary
sf
-formatted networks via specification of custom weighting
profiles, along with highway type and ID columns in data.frame.dodgr_dists
inherit the names of
routing points (from
and to
parameters).Initial CRAN release.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
