GPS match in 3D map

[brunoeducsantos]

Hi @jagodki ,
It is more a question than a issue. My question is if we can use this offline map matching for 3D mapping, i.e., match GPS points in a 3D map.
Regards,
Bruno

Hi Bruno,

that is a really good question. At the moment, the plugin uses only the x- and y-coordinates for the calculations (z- and m-values will be ignored). 3D calculations would be a great improvement because a lot of road infrastructure is not on the same height (e.g. bridges, motorway junctions). The calculations I realized by myself can be easily edited for 3D-coordinates. The main problem will be the functions from the PyQGIS API. I am not sure, if e.g. the Dijkstra-Algorithm of PyQGIS uses 3D-coordinates if available. That has to be investigated.

I will create a new project from this issue to have a look on the 3D-support. But I am very busy with another project and I planned a new major release of the plugin for the next months. So I am not sure, if I can work on your question already this year or not before next year.

Sincerely,
Christoph

Great to hear it was a good suggestion.

Hello, I am a graduate student. I would like to ask you how to draw the corresponding vehicle track on the map according to the existing GPS data set of vehicles (including longitude and latitude).Thank you. Looking forward to your reply.

@love-freedom777 I moved your question into a new issue, because it has nothing to do with the original question of this issue. In issue #24 we can discuss your question (I already answered you there) in detail and take this issue clean 😺
