FindLocationNameExample and OnlineMapsGoogleGeocodingResult

Something like that:

private void OnQueryComplete(string s)
{
    OnlineMapsGoogleGeocodingResult[] results = OnlineMapsGoogleGeocoding.GetResults(s);
    // Show response in console.
    foreach (OnlineMapsGoogleGeocodingResult result in results)
    {
        Debug.Log(result.formatted_address);
    }
}

Looking at the results that gives me, I wonder is there a way to get more information about it? Right now it's giving me the street address, the city, state, etc. But if I click on a golf course, I'd love to get that information, or a hospital or what have you. Is that information in the geocoding result, or do I need to do a different call to OSM or something?

Thanks!

I was hoping the location_type or types properties might have that info, but they don't seem to. Only things like "APPROXIMATE" and "political" etc. Any way to know if I just clicked on a hospital or a tennis court or a parking lot?

Thanks!

Thanks! I'm trying to figure out how to properly use OnlineMapsGooglePlaceDetails.FindByPlaceID.

The documentation says it returns a "Query instance to the Google API." and when I look at it in the code, Visual Studio says it returns an OnlineMapsGooglePlaceDetails type.  OnlineMapsGooglePlaceDetails.GetResult takes a string as a parameter, so I'm not sure how to turn the OnlineMapsGooglePlaceDetails return value from FindByPlaceID into a string I can pass into GetResult. What am I missing here?

Thanks very much!

I see.
The problem is that you are using the wrong service.
Google Geocoding API returns the address.
To find objects near the location, you need to use Google Places API.
Example:

using UnityEngine;

public class GetLocationInfo:MonoBehaviour
{
    public string key;

    private void Start()
    {
        OnlineMapsControlBase.instance.OnMapClick += OnMapClick;
    }

    private void OnMapClick()
    {
        OnlineMapsGooglePlaces.FindNearby(OnlineMapsControlBase.instance.GetCoords(), 20, key).OnComplete += OnFindNearbyComplete;
    }

    private void OnFindNearbyComplete(string response)
    {
        Debug.Log(response);
        OnlineMapsGooglePlacesResult[] results = OnlineMapsGooglePlaces.GetResults(response);
        foreach (OnlineMapsGooglePlacesResult result in results)
        {
            Debug.Log(result.name);
            Debug.Log(string.Join(", ", result.types));
        }
    }
}

Well, that gets me part of the way there. It seems to work okay on buildings- I click on a dentist and I get:

dentist, health, point_of_interest, establishment

But I click on a golf course and I get:

locality, political
neighborhood, political

If I go to OpenStreetMaps and use their Query Features button, I click on a golf course and I get:

Nearby features
Cycle Path #189157195
Golf Course Balboa Municipal Golf Course
Sand #317312157
Grass #317312158
Grass #317312623
Enclosing features
Golf Course Balboa Municipal Golf Course
City Boundary Los Angeles
County Boundary Los Angeles County
State Boundary California
Timezone America/Los_Angeles Timezone
Country Boundary United States of America

So it looks like for what I'm trying to do an OSM query might be the way to go. Is the means of doing so using those functions similar to what you provided for the Google Places API?

Thanks!

I made a little research, and for your purposes it's best to use Foursquare.
Online Maps does not have classes to work with this web service, but that does not mean that you can not use it.
Example:

using System;
using UnityEngine;

public class GetInfoFromFoursquare:MonoBehaviour
{
    public string clientID;
    public string clientSecret;

    private void Start()
    {
        OnlineMapsControlBase.instance.OnMapClick += OnMapClick;
    }

    private void OnMapClick()
    {
        Vector2 coords = OnlineMapsControlBase.instance.GetCoords();
        OnlineMapsWWW www = new OnlineMapsWWW("https://api.foursquare.com/v2/venues/search?ll=" + coords.y + "," + coords.x + "&client_id=" + clientID + "&client_secret=" + clientSecret + "&v=" + DateTime.Now.ToString("yyyyMMdd") + "&limit=1");
        Debug.Log(www.url);
        www.OnComplete += OnRequestComplete;
    }

    private void OnRequestComplete(OnlineMapsWWW www)
    {
        if (!string.IsNullOrEmpty(www.error))
        {
            Debug.Log(www.error);
            return;
        }

        Debug.Log(www.text);
        OnlineMapsJSONItem json = OnlineMapsJSON.Parse(www.text);
        OnlineMapsJSONItem venue = json["response/venues/0"];
        if (venue != null)
        {
            Debug.Log(venue["name"]);
            Debug.Log(venue["categories/0/shortName"]);
        }
    }
}

P.S. To get id and secret you need to create an application.

Thanks for that example, it's especially useful to use as a guide for when I want to use a resource for which there are no classes native to Online Maps.

It doesn't seem to give me what I can get from OSM, though. To give you an example, the area I'm testing in has some features that work perfectly when I do a Query Feature via OSM, but return misleading results when using the Foursquare code above.

An example. Set the Tileset control to:

latitude 34.1820437820025
longitude -118.478416533137
zoom 17
provider OSM
type Mapnik

Clicking in the red national guard station near the top of the map using the Foursquare Code gives me

Carlo Inc
Office 

and when I query feature in OSM I get

Nearby features
No features found
Enclosing features
Military Area Sepulveda Air National Guard Station
{etc}

If I click in the middle of the big Water Reclamation Plant in the center of the map, using the Foursquare code, I get

Woodley Avenue Park
Park

but when I query feature on OSM I get:

Nearby features
Service Road #94233762
Industrial #306664814
Enclosing features
Industrial Area Tillman Water Reclamation Plant
{etc}

I think what's going on is that there aren't as many map features defined (who'd want to "check in" to a water treatment plant?), and it's returning the nearest one, without quite so much detail, as Foursquare doesn't have the boundaries of each feature defined the way OSM does. That means if the point is closer to the center of one feature, Foursquare can't tell you're within the boundaries of another feature.

Is there a way for me to get the results yielded doing a Feature Query on OSM?

Looking here:
https://blog.openstreetmap.org/2014/12/ … y-feature/

Leads me to here:
http://wiki.openstreetmap.org/wiki/Downloading_data

But I'm not sure if that's the right path to victory here. If you can give me an example of that Feature Query tool using Online Maps, I think I'll have what I need to move forward.

Thanks again, and I hope this thread has proved instructive to others who might be reading along.

Their Export tab works not only with the data but with the query. Exporting the above query to text gets me this, which seems to be working for me to get everything, it's a matter of parsing through the data at that point.

string requestData = "(node(34.16870691998642, -118.50798726081847, 34.17677564022297, -118.49230170249939);<;);out meta;";

If you see any reason I shouldn't be continuing this line of inquiry, do let me know. Thanks!
