Which grid system would be most suitable for mapping a long, narrow region?

• A. Orthomorphic Grid
• B. British Grid
• C. Military Grid (UTM)
• D. Transverse Mercator Grid

Answer: (B)

The main idea here is choosing a grid that's optimized to minimize distortion across the specific area you're mapping. For a long, narrow region, you want a projection that keeps distances and positions accurate along that strip and uses a single, consistent grid across the whole area. The British Grid is built on a Transverse Mercator projection tailored for Great Britain, so the grid squares stay relatively uniform and measurements remain reliable throughout the entire country without jumping between zones. That single, region-focused framework makes it the best fit for mapping a long, narrow region that lies within that area. The other options either prioritize equal-area properties at the expense of shape and distance, rely on multiple UTM zones (which adds complexity and distortion when the region stretches across several zones), or aren’t specifically tuned to the region in question.
