Which application is likely enhanced by using slope analysis?

Using slope analysis in the context of land use planning is particularly beneficial because it provides critical data about the terrain that can influence how land is developed and utilized. Slope analysis assesses the steepness or degree of incline of the land surface, which is a vital factor when determining the best uses for a given area.

For land use planning, understanding the slope of the terrain can help in making decisions about zoning, infrastructure development, agriculture placement, and environmental conservation. For instance, steep slopes may be unsuitable for construction due to risks like erosion or landslides, while gently sloping lands might be ideal for farming or building. Additionally, slope analysis can aid in assessing drainage patterns and flood risks, ensuring that land is developed in ways that are both sustainable and safe.

In contrast, while the other applications, such as traffic flow analysis, population density mapping, and wildlife migration patterns, may also be impacted by slope, they do not rely as heavily on slope data for their primary analyses as land use planning does. Therefore, considering the fundamental role of slope in determining suitable land use, option B stands out as the most relevant choice.
