Android Code Snippet [B4X] Free Geolocation Nominatim (Geocoding API)

Here's a demo of how to use the nominatim geocoding API for free.

Note:
There are other geocoding options if you want to know, leave your comments.

Demo file attached

Sub GeoCoderNominatim(Query As String) As ResumableSub
    Dim ResultURL As String
    Dim j As HttpJob
    Dim Parameter() As String = Array As String ("q", Query, "format", "json", "limit", "1", "addressdetails", "1")
    Try
        j.Initialize("", Me)
        j.Download2("https://nominatim.openstreetmap.org/search", Parameter)
        j.GetRequest.SetHeader("Content-Type","application/json")
        Wait For (j) JobDone(j As HttpJob)
        If j.Success Then
            ResultURL = j.GetString
        Else
            Log(j.ErrorMessage)
        End If
    Catch
        Log(LastException)
    End Try
    j.Release
    Return ResultURL
End Sub

Enter address get location

Enter location get address

Super and thank you!
Runs well.

I want to thank you again for this great code!
Is there also something free where you can calculate the correct distance and travel time?
What is that for in your code?

#Region Shared Files
#CustomBuildAction: folders ready, %WINDIR%\System32\Robocopy.exe,"..\..\Shared Files" "..\Files"
'Ctrl + click to sync files: ide://run?file=%WINDIR%\System32\Robocopy.exe&args=..\..\Shared+Files&args=..\Files&FilesSync=True
#End Region

'Ctrl + click to export as zip: ide://run?File=%B4X%\Zipper.jar&Args=Project.zip

For my projects I use project-osrm.org, which is free.

Project OSRM

OSRM API Documentation

sample:

OpenStreetMap Routing with Open Source Routing Machine

map.project-osrm.org

Note:
I will post a demo soon.
Since all nominatim or OSRM APIs are in a class that I have developed.

Verry Nice

excellent contribution,
A query, how can you do an autocomplete like google place does?

 

[jose luis gudino]

Very Nice

Your contribution is very interesting and useful, both for the code and for the shared experience on this topic
May I know if the demo you are referring to has already been posted?

Soon:
I am adding more geocoder providers.

 

[John Naylor]

Brilliant! I'll definately be using this.

 

[Mashiane]

Thank you so much for this! Just applied it in my project, works perfectly!

Can you please provide this example source code, thank you,

 

[TILogistic]

Not at the moment, but I will post all the classes that can be used with GoogleMaps and GeoCoder.

PS: I will create a post of helper function classes for Google Maps and others, where I will accept donations.

Interesting, can we geocode huge numbers of locations using nominatim or OSRM APIs, all is there a fair use ?

Thanks

OSRM APIs, all is there a fair use
see:

Nominatim Usage Policy (aka Geocoding Policy)

operations.osmfoundation.org

There are several OSM projects that are community-based and free, some of which have usage policies.
and others where you can have your own mosaic server or geocoder server.
