PulssiliDARissa

PulssiliDARissa, often referred to as Pulsed LiDAR, is a remote sensing technology that utilizes pulsed laser light to measure distances to objects. The system emits short pulses of laser energy and measures the time it takes for these pulses to return to the sensor after reflecting off a surface. By knowing the speed of light, the time-of-flight can be converted into a precise distance measurement. This information, when collected for numerous points, creates a three-dimensional representation of the scanned environment.

The core components of a PulssiliDARissa system include a laser scanner, a GPS receiver, and an inertial measurement unit (IMU). The laser scanner emits the pulses and detects the returning echoes. The GPS receiver provides the absolute geographic position of the sensor, while the IMU records its orientation (roll, pitch, and yaw). Combining these data streams allows for the accurate georeferencing of the generated point cloud.

PulssiliDARissa technology finds applications in various fields. It is widely used in topographic mapping and surveying to create detailed digital elevation models. In forestry, it helps in estimating tree height, canopy density, and biomass. The automotive industry employs it for autonomous driving systems to detect obstacles and map surroundings. Other uses include archaeology for uncovering hidden structures, urban planning for creating 3D city models, and disaster management for assessing damage. The resulting data is a dense collection of 3D points, often referred to as a point cloud, which can be further processed and analyzed to extract meaningful information.
