Mapping and surveying* with a drone using both RGB (Red, Green, Blue) and LiDAR (Light Detection and Ranging) technologies is a powerful approach that enables detailed and comprehensive data collection for various applications, from land development and construction to environmental monitoring and infrastructure management. Whether working with your surveyor or partnering with one of ours, Drones Inbound can provide survey grade data faster and many times, more accurately than traditional means. Here's how the combination of RGB and LiDAR data enhances mapping and surveying with a drone:
1. RGB Imaging:
- Aerial Photography: The drone captures high-resolution RGB images from various angles and altitudes. These images provide detailed visual information about the surveyed area, including color, texture, and surface features.
- Orthomosaic Generation: Software processes the RGB images to create orthomosaics, which are high-resolution, georeferenced, and orthorectified images that accurately represent the terrain. These orthomosaics serve as a base layer for mapping.

2. LiDAR Technology:
- Laser Scanning: LiDAR sensors on the drone emit laser pulses and measure the time it takes for the laser to bounce back after hitting objects on the ground. This process generates precise 3D point cloud data.
- Point Cloud Generation: The collected LiDAR data is processed to create a dense and highly accurate point cloud. Each point in the cloud represents a location in 3D space and includes information about the distance from the sensor.
- Digital Elevation Models (DEMs) and Digital Surface Models (DSMs): The LiDAR point cloud data is used to generate DEMs and DSMs. A DEM represents the bare earth surface, while a DSM includes all objects on the terrain, such as buildings and vegetation. These models provide elevation information for the surveyed area.

3. Integration of RGB and LiDAR Data:
- Fusion of Data: RGB and LiDAR data can be integrated or fused to create a comprehensive dataset that combines visual and spatial information. This integration enhances the accuracy and detail of the mapping and surveying results.
- Colorized Point Clouds: RGB data can be applied to the LiDAR point cloud to create colorized point clouds. This allows for the visualization of point clouds with realistic colors, making it easier to identify features and objects.
- Enhanced Classification: The fusion of RGB and LiDAR data aids in the classification of objects and terrain, distinguishing between different land cover types, vegetation, buildings, and other features.
