Application of Airborne LiDAR Technology in Power Optimal Line Selection
First of all, it is necessary to analyze the map and image data, and select the appropriate transmission line path according to the actual situation to facilitate the subsequent construction of overhead transmission lines. Secondly, after the initial path selection is completed, it is necessary to use airborne lidar technology for measurement according to the selection results. The measurement process must ensure comprehensiveness, scientific processing through advanced technology, and field research using technical functions. Finally, the laser radar is used to integrate the data, and the results are fused with each other. The staff optimizes the circuit through the circuit design software and outputs the final result.

The difference between DEM(Digital Elevation Model), DSM(Digital Surface Model) and DTM(Digital Terrain Model)
DEM DEM, Digital Elevation Model, is a 3D computer graphic representation of elevation data. DSM DSM, Digital Surface Model, represents the earth's surface and includes all objects on it, generally used in landscape modeling, urban modeling and visualization applications. DTM DTM, Digital Terrain Model, represents bare ground without any objects such as plants and buildings, and is often used for flood or drainage modeling, land use studies, geological applications, and other applications.

LiDAR Data Processing - Outliers
Some data in the lidar data are obviously unreasonable and need to be eliminated. These points are called outliers. The elevation system is generally processed at the same time as the plane coordinate system, and the geodetic height is converted into a normal height. The most important step in office data processing is the filtering of lidar data. More > -

How to make a real 3D model
The production of real-world 3D models starts with data collection. The realism of the model lies in the same color as the real world, which is derived from the imagery taken from the sky. At present, oblique photogrammetry technology is mainly used for aerial photography. More > -

What are the uses of Digital Elevation Model
Digital Elevation Model is a data set of plane coordinates (X, Y) and elevation (Z) of regular grid points within a certain range. It mainly describes the spatial distribution of regional geomorphology, and uses contour lines or similar three-dimensional models for data collection. Acquisition (including sampling and measurement), followed by data interpolation. More >
