Is there a better way to create a map in photoshop?

Here's my workflow:

I have a google earth picture as a reference

I am creating paths (not shapes) for roads, buildings, and other features

When I am happy with a path, I "stroke path" onto its corresponding layer.

This is large property and there will be hundreds of features at different levels of detail.

I figure this approach will allow me to create and edit paths, and "print" them to layers at the very end.

However, I have no idea what I'm doing and invented this method myself.

Does anyone have any advice for me? Is there any way to do this better? I'd like to get the method figured out before I dive further into this project.

See photos below for an example of what I am doing. Thanks for any help with this.
