Using Google Maps' API v3, is it possible to draw a polygon on a Google maps and get a list of all the street names that fall within that polygon?

    Have you tried anything? I can't see an explicit method for that, but I can think of some terrible hacks. Compute a fine grid (2m x 2m) of points over the polygon, reverse-geocode, get the street name from the response. Or use OpenStreetMap instead, and the Overpass API which (I think) can do this. – Spacedman Jul 28 '18 at 16:25
  • you can send the lat,lng of your polygon as directions like maps.googleapis.com/maps/api/directions/… – Mapperz Jul 28 '18 at 21:06

So I used the solution (OpenStreetMap) from @Spacedman:

  1. Download the .pbf for your country http://download.geofabrik.de
  2. Download the polygon file for the desired municipality from https://github.com/JamesChevalier/cities or create your polygon file (.poly) here : http://share.mapbbcode.org/
  3. Download lasted version from Osmosis https://wiki.openstreetmap.org/wiki/Osmosis#Latest_stable_version
  4. Do this:

    osmosis --read-pbf-fast you_file_country-latest.osm.pbf file="your_file_country-latest.osm.pbf" --bounding-polygon file="your_municipality_polygon.poly" --write-xml file="your_file_out.osm"

enter image description here 5. In the .osm file, you obtain all the street names, to extract the names use the option (regex) of notepad++

It's complex but it works, but I still have to find a way to do it directly from Google API

    I think you should take a look at Overpass API, the following query will return all highway=* with a name in your bounding box: overpass-turbo.eu/s/AD5 ... Polygon selection would also be possible. – mmd Jul 28 '18 at 21:22
