Labeling streets

[michael-prange]

Is there an easy way to extend the code to allow streets to be labeled?

Yes! This can be easily added.

Object MapData has a field roadways that has a Vector with road descriptions.

For an example consider the sample map:

mx = get_map_data(joinpath(dirname(pathof(OpenStreetMapX)),"..","test/data/reno_east3.osm"),use_cache=false)

The first roadway has the following nodes:

julia> mx.roadways[1].nodes
4-element Vector{Int64}:
 2441017888
 2441017878
 2441017870
 2975020216

The name of the roadway (here Pyramid Way) can be found in the tags field:

julia> mx.roadways[1].tags
Dict{String, String} with 11 entries:
  "oneway"     => "yes"
  "lanes"      => "1"
  "surface"    => "asphalt"
  "name"       => "Pyramid Way"
  "horse"      => "no"
  "lit"        => "yes"
  "highway"    => "secondary"
  "turn:lanes" => "left"
  "source"     => "Bing"
  "foot"       => "no"
  "bicycle"    => "no"

Hence all you need to do is to iterate along roadways, take the first node, get it location and than do the plotting.

Thanks. I will work on a function that adds road names to a map.
