A cartographer uses LiDAR data to map terrain, with each data point representing 0.25 square meters. If a valley spans 1,600 square meters and the data density must be increased by 25% for high-resolution modeling, how many data points are required?

**Why High-Resolution Terrain Mapping Matters — and How Density Drives Precision** In fields like urban planning, agriculture, environmental monitoring, and emergency response, accurate terrain modeling is no longer optional—it’s foundational. A cartographer uses LiDAR data to create detailed 3D representations of landscapes, where each data point captures just 0.25 square meters. This level of precision enables professionals to detect subtle elevation changes, assess flood risks, or monitor erosion over time. With a valley spanning 1,600 square meters under analysis, the push for higher data density reflects a growing demand for sharper, more actionable insights. As digital mapping technology advances, the balance between point density and processing efficiency becomes critical. Boosting data density by 25% doesn’t just enhance visual clarity—it unlocks deeper analytical capabilities, supporting smarter infrastructure decisions and risk assessments. This shift aligns with broader trends in geography, geospatial analytics, and smart land management across the U.S. **Why Engineers, Land Managers, and Planners Are Turning to Higher Density LiDAR**
