- High spatial resolution and accuracy
- Ability to penetrate vegetation cover for bare-earth models
- Rapid data collection over large areas
- Compatibility with GIS and remote sensing tools
- Supports applications in topography, urban planning, forestry, and environmental monitoring
Pros
- Provides highly detailed and accurate elevation models
- Enables advanced analysis for terrain modeling and change detection
- Useful for a wide range of industries including archaeology, forestry, and civil engineering
- Enhances decision-making with precise geospatial information
Cons
- Data processing can be computationally intensive and require specialized expertise
- LEAD to high costs for data acquisition and processing in some cases
- Quality depends on equipment calibration and environmental conditions during data collection
- Large datasets may pose storage and management challenges
