Utilizing LiDAR data with Surfer - A combination of point cloud data and surface modeling -
In recent years, with the widespread use of drones, LiDAR data has been utilized in a wide range of fields, including high-precision topographic surveying, agriculture, construction sites, and archaeological investigations. In Japan, LiDAR data has been made available on several sites. Here, we will introduce how to utilize LiDAR data using Surfer, which is equipped with surface modeling and GIS capabilities.

basic information
Representing LiDAR data as a point cloud map Surfer can import point cloud data in LAS or LAZ format. It is also possible to improve efficiency by filtering based on certain conditions or classifications. Grid method specifically for point clouds To grid LiDAR data (including all areas such as buildings and trees), using the Create Grid command designed for point clouds allows for the creation of grid data at a much faster rate compared to various grid methods standardly equipped in Surfer. Creating terrain models from LiDAR data The advantage of using LiDAR data is that it allows for the extraction of surface data, enabling the use of very high-precision terrain models. High-precision data obtained as point clouds can be gridded using advanced interpolation methods such as Kriging. Incorporating any section of LiDAR data into the model It is also possible to cut out a portion of LiDAR data and combine it with various surface models created in Surfer.
