An army unit needs to establish a communication relay on high ground. Using DEM (Digital Elevation Model) data, they identify that the terrain rises from 800m to 1,400m over a horizontal distance of 5 km. What is the gradient percentage of this slope, and how would this be classified in military terrain analysis?
- 12% gradient, moderate slope
- 15% gradient, steep slope
- 10% gradient, gentle slope
- 8% gradient, gentle slope
