MfwOfflineGeocoding
The MfwOfflineGeocoding plugin provides complete address information, including a structured full address, postal code and other information. The information is generated based on the stored data. It is also possible to obtain data about an object by coordinates.
Main use cases:
- obtaining an address by coordinates
- receiving coordinates by address
- getting a list of hints by address

Clone a repository
You need to add the plugin to the project root as a submodule:
git init
mkdir plugins
cd plugins
git submodule add https://os-git.omprussia.ru/MapsFramework/MfwOfflineGeocoding/ && cd MfwOfflineGeocoding &&
git submodule update --init --recursiveSetting up the .spec file
In the .spec file in the rpm directory after the lines:
%install
%make_installyou need to add the following lines:
%define __requires_exclude ^(libMfwOfflineGeocoding.*).*$

")Register MfwOfflineGeocoding qml type
You need to add the following code to main.cpp:
#include <auroraapp.h>
#include <QtQuick>
#include <MfwOfflineGeocoding/MfwOfflineGeocoding>
int main(int argc, char *argv[])
{
qmlRegisterType<MfwOfflineGeocoding>("MfwOfflineGeocoding", 1, 0, "MfwOfflineGeocoding");
//generated code
}Use MfwOfflineGeocoding in qml components
Add MfwOfflineGeocoding to the qml component:
//oter imports
import MfwOfflineGeocoding 1.0
Page {
MfwOfflineGeocoding {
offlineGlobalPostalPath: "path/to/postal/global"
offlineCountryPostalPath:"path/to/postal/country"
offlineGeocoderPath: "path/to/geocoder-nlp"
}
}Setting up the MfwOfflineGeoCoding component
Component Base State
-
1. Code:
MfwOfflineGeocoding { offlineGlobalPostalPath: "path/to" offlineCountryPostalPath:"path/to" offlineGeocoderPath: "path/to" } -
2. Local data source
- 2.1 Path to directory postal/global
- 2.2 Path to directory postal/country
- 2.3 Path to directory geocoder-nlp
Basic use case
Receiving an address within the radius of the area around a point with coordinates: geocoder.findAddress(geocoordinate, radius).
The method returns a json object that contains a structured address, postal code and other fields.
Obtaining local data necessary for the plugin to work
Data is generated using a script.
