This plugin adjusts a GPS track on a street network (map-matching) semi-automatically.
Please read the plugin documentation before using it.
The map-matching process has 3 steps.
This step prepares the data for the map-matching process.
It corrects the topology of the street network and verifies the validity of the input.
The required fields are:
Select the layer to use to adjust the GPS track.
The list is composed of every active layers of type LineString.
The type
Select the point layerto match on the network. The list shows every active layers of type Point.
Select an unique indentifier for every points giving the order of the features. The list shows every attributes of type "Integer/Integer64/int/int8" present in the selected point layer.
Enter the range of the buffer that will be created around every points. Every line intersecting this buffer will be considered for map-matching. A bigger value implies a longer computing time
This step matches the points of the GPS track on the street network. After the first iteration, the user can modify the selected lines and match the points again.
Two fields can be specified:
Select the attribute representing the speed of every points. The list shows every attribute of type "Integer/Integer64/int/int8" present in the selected point layer. This field is only necessary to use the matching method "by speed".
Select the type of matching to use. Three options are available.
In this step, the results are exported in the selected format. You can also do it manually from QGIS
Three options are available:
Select the matched track present in the adjacent dropDown list to export.
Check to export the polyline representing the selected path.
Check to export every elements selected in the settings inside a single file.
