Airborne laser scanning (ALS) point clouds have emerged as a predominant data source for
the generation of digital elevation models (DEM) in recent years. Traditionally, the …

Filtering out vegetation from a point cloud based on color is only rarely used, largely due to
the lack of knowledge of the suitability of input information (color, vegetation indices) and the …

The alpine environment with a high degree of nature protection is characterized by complete
non-intervention. The processes and phenomena occurring in it are exclusively of a natural …

The classification of point clouds is an important research topic due to the increasing speed,
accuracy, and detail of their acquisition. Classification using only color is basically absent in …

The documentation of historical artefacts and cultural heritage using high-resolution data
obtained from unmanned aerial vehicles (UAVs) is of paramount importance in the …

The documentation of historical remains and cultural heritage is of great importance to
preserve historical knowledge. Many studies use low-resolution airplane-based laser …

Salt marshes provide diverse habitats for a wide range of creatures and play a key defensive
and buffering role in resisting extreme marine hazards for coastal communities. Accurately …

Mobile map** systems are part of modern data collection in geodesy. It is one of many
surveying methods where field collection is performed in a short time. Among their …

Ground filtering is a fundamental step in airborne LiDAR data processing toward a variety of
applications. However, existing algorithms remain tremendously challenging in complex …

To enhance the filtering accuracy in complex environments, a segmentation-based
