How to get Transform data of a Tile Map.

Is it possible to get transform data (position specifically) of a specific Tile Map?
It looks like tileData.transform would be responsible for this, but I can't seem to figure it out. If anyone could post a quick example of how GetTileData and TileData are used in CS that would be great. Thanks!

Edit: It occurs to me that I should probably explain what I'm trying to use it for:

I've created a set of tiles on the tilemap designated as a spawn zone. I'm trying to get the bounds and location of this box so I can spawn enemies within a random range inside the bounding box of said tiles. Not sure if this is even possible.
