In recent years, aerial photogrammetry conducted by Unmanned Aerial Vehicles (UAVs) has seen increasingly widespread application. To achieve efficient monitoring and management while reducing long-term labor and resource costs, the PIX4D software can rapidly process images captured by UAVs. The software generates deliverables such as 3D Point Clouds, Digital Surface Models (DSM), and Orthomosaics. It also provides tools for visualizing and editing the 3D point cloud and tie-points (ray intersections) within the software interface, enabling subsequent effective geospatial analysis and integration. Examples include slope analysis and point cloud digitization. By overlaying, comparing, and interpreting the processed terrain and imagery, users can obtain accurate spatial analysis results, such as distance measurements and earthwork volume calculations, achieving the technical integration of spatial information for real-time monitoring, decision-making, and planning. Currently, professional users in over 88 countries worldwide utilize PIX4D software, demonstrating the global trust and affirmation it has earned. GeoForce Technology Inc. (群立科技) became an authorized distributor in 2010 and is the official PIX4D partner in Taiwan. For years, the company has been dedicated to advancing UAV aerial photogrammetry. PIX4D is one of the best-selling UAV image processing software packages in Taiwan, highly favored and adopted by many relevant units in fields such as soil and water conservation, disaster prevention, construction, and engineering consulting.
