My table has made great use of https://shmeppy.com for remote-play maps. The maps it makes are much less sophisticated (just painting color on the squares and lines of a grid). What it gives you instead are player/monster tokens that everyone can see, measuring tools, and "laser pointers" to allow participants to draw attention to a region of the map while speaking.

EDIT: also an awesome fog of war feature; how could I forget?
