Hi again! We're working through the Sector Map creation process and I'm wondering how to interpret the coordinate-pair results in Step 2, "Add Terrain"

Here's an example:

1. I roll d6 to see how many terrain features the map has -- I rolled 1.
2. Roll d6 on the Terrain Table to determine terrain type -- I rolled 3, "Forest".
3. Roll 2d20 for start coordinates [x, y]  -- I rolled 1 and 1, so my forest starts at [1,1] 
4. Roll 2d20 for end coordinates [x, y] -- I rolled 4 and 3, so my forest ends at [4, 3]

Is this a *rectangle* of forest from [1,1] to [4,3]?

 
Or a *line* of forest going straight-ish from [1,1] to [4,3]? 

[Images didn't post the first time, edited to re-add them]

Hey Skeolan, I go with the line approach (but may widen it from 1 square). The purpose of this exercise is to create a few barriers on the map for land based vehicles to navigate around so the line approach works better here. Thanks for the feedback.
