OSM Offline map in user accessible directory

Markus Ippy

Hello

I am trying to implement offline maps in my application. I tried the example below and it works perfectly.
http://blog.qt.io/blog/2017/05/24/qtlocation-using-offline-map-tiles-openstreetmap-plugin/

However i would like to store the map tiles in a user accessible folder. Ideally a relative Path in the same directory as the executable.
I tried to modify the Plugin Parameter to a absolute path on windows for testing :
value: 'c:/offline_tiles/' but that does not seem to work .Could i please get some advice on how to do that ?

Thank you in advance

    plugin: Plugin {
        name: 'osm';
        PluginParameter {
            name: 'osm.mapping.offline.directory'
            value: 'c:/offline_tiles/'
        }
    }

Hi,

You should also add which version of Qt you are using as well as the Windows version and compiler.

@SGaist Sorry , using QT5.9.1 pn windows 10 with mingw
but planning to run it on raspberry pi later.

I just found the issue now , Map types had to be changed from 1 to 2
activeMapType: map.supportedMapTypes[2] and changed the value to the relative path of my Executables directory
value: 'file:///offline_tiles/'
my code looks now like this and it works now when i switch my internet connection off :

import QtQuick 2.8
import QtLocation 5.8
import QtPositioning 5.8

Item {
id: mapItem
anchors.fill: parent
Rectangle{
anchors.fill: parent
Map {
id: map
anchors.fill: parent
activeMapType: map.supportedMapTypes[2]
zoomLevel: 1
plugin: Plugin {
name: 'osm';
PluginParameter {
name: 'osm.mapping.offline.directory'
value: 'file:///offline_tiles/'
}
}
}
}
}
