Geostory Enhances 3D Spatial Information with Hybrid Aerial LiDAR

Geostory is strengthening its capabilities in building 3D spatial information by combining hybrid aerial LiDAR equipment with data processing technology. On the 25th, the company announced that it is leading the technological standards in the 3D spatial information industry with its high-precision hybrid aerial LiDAR technology. The company operates TerrainMapper and CountryMapper equipment. Hybrid aerial LiDAR measures the location and height of terrain and buildings using lasers, combining this with high-resolution aerial imagery. Geostory simultaneously acquires 3D point cloud data and high-resolution digital images, applying 'RGB point cloud data mapping technology.' When color information is integrated into the point cloud data, the readability of buildings, roads, and terrain is enhanced. This technology compensates for the low identification limits of existing aerial LiDAR data and is used to classify and extract terrain elements in urban areas. Data correction technology is also a key component, and Geostory extracts the outlines and altitude values of individual objects even in densely populated urban areas through its self-developed correction process. Aerial LiDAR-based 3D data requires not only the performance of the capturing equipment but also the alignment of point clouds and images, followed by a process to correct errors after interpreting objects. Potential applications include autonomous driving, urban air mobility (UAM) infrastructure development, and analysis of sunlight and view rights. A representative from Geostory stated that they will lead next-generation spatial information convergence technology with a focus on data interpretation and correction technology.
