Navigation without lidar

Hello. I am new to ROS and not sure exactly where this would fall under, so please bear in that in mind..

I am working on a differential drive robots project. We are using an off the shelf positioning system based on cameras(dragonfly). It gives us x,y,z (relative to a defined origin) or WGS84 coordinates.

It creates SLAM internationally without lidar.

All of the navigation and path planning seem to operate directly off of slam created from the lidar.

Is there a module that works with just coordinates for navigation/path planning?

Thanks so much!
