Tools for players to mark up a map of the Stolen Lands?

[Shadowfoot]

I’d like my players to be able to mark up a digital stolen lands map. What is a good way to do that? Ideally they will be able to do this between sessions. In some ways I want it to be like a digital whiteboard.
Use of a VTT doesn’t seem the right way, as it requires the map to be be set as the current page between sessions.

You could try doing a Google Drawing. They would be able to zoom in on specific sections and make notations from there.

There may also be some kind of cloud-based digital whiteboard you could use, as well, but I don't know of any off the top of my head.

Not sure if he updated it, but used this for first version.

I've been using MapTool. It... has some issues. The biggest one I complain about constantly is that text labels are barely a vestigial feature, making it near-impossible for my players to know what any given icon means. But placing the icons themselves works pretty well, once I found some free icons to work with, and importing the art from the PDFs was straightforward enough (use the chapter PDFs, not the whole book).

You could always just use Google Slides in a pinch too.
That's what my group's going to do.
