Mapping System PM-1500 for mangrove growth monitoring
Mangrove is one of the Marine ecosystems with the highest
productivity in the interlacing zone of sea and land in tropical
and subtropical coastal zones. Mangrove plays an extremely
important role in purifying seawater, preventing wind and waves,
maintaining biodiversity, sequestration and carbon storage, etc.
Through the growth monitoring of mangroves, we can timely
understand the growth status of mangroves, which is very important
for the protection and restoration of ecosystem.
The mangrove growth status monitoring is mainly based on the
spectral information and height information of mangrove branches
and leaves. At present, the growth status monitoring based on
traditional remote sensing means mainly provides spectral
information, but cannot provide the height information in the
vertical direction. Airborne LiDAR system combines the spectral
information obtained by camera sensor and the height information
obtained by LiDAR to provide a new monitoring method for mangrove
growth monitoring.
Based on PM-1500 airborne LiDAR system, it can simultaneously
obtain the image data taken by the camera while obtaining the laser
point cloud data points. The combination of the two can obtain the
spectral information and height information of mangrove, so as to
provide rich data sources for mangrove growth monitoring.

Advantages
1. The super high frequency of up to 2 million points per second
makes the point cloud data more refined and can more truly reflect
the landform of the survey area, rather than fitting the ground
object coordinates.
2. The ranging accuracy of PM-1500 airborne laser measurement
system can reach 5mm@50m, and the comprehensive accuracy of the
system is better than 5cm, meeting various high-precision
application scenarios.
3. The ultra long ranging of 1500 meters greatly ensures the
operation safety in the environment of large topographic
fluctuation and greatly improves the point cloud acquisition
efficiency.
4. The overall weight of the system is less than 4.4kg. It can be
easily carried by one person, whether by plane or high-speed rail.
5. The system can obtain up to 4 echo signals, and can penetrate
trees and feed back the most real surface information even in
densely vegetated areas.
