2010. Compar- isons between field-and LiDAR-based measures of stand structural complexity. Canadian Journal of Forest Research 40:761-773.Kane, V., McGaughey, R., Bakker, J., Gersonde, R., Lutz, J. and Franklin, J. (2010). Comparisons between field- and LiDAR-based measures of ...
A backfill system in underground mines supports the walls and roofs of mined-out areas and improves the structural integrity of mines. However, there has been a significant gap in the visualization and monitoring of the backfill progress. To better obser
LiDAR measures the distance or range to a target by illuminating the target with a pulsed laser light and measuring the reflected pulses with a sensor. It can directly represent external structures and carry out profiling for objects or trees. Laser Scanning (LS) profiling systems consist of a ...
However, existing GDEMs have been found to be too inaccurate for SLR related assessments, amongst others because they are created using radar data that is unable to penetrate dense vegetation and also measures elevations of non-ground features in built-up areas (Gesch, 2018; Hooijer & Vernimmen...
Cross-platform data interchangeability was assessed by comparing the interchangeability, which measures the absolute difference in overall accuracy (OA) or macro-F1 by comparing the cross-platform interchangeability. It is noteworthy that relying solely on aerial photographs is inadequate for achieving ...
to estimate AGB have been demonstrated. The reason for an improved result from the UAS-lidar sampling technique could be because UAS-lidar covers a larger area with more points representing a wide range of vertical and horizontal vegetation structural changes and accurately measures terrain morphology...
3.2. IMU Measurement Model In general, the IMU measures the moving object's rotational motion in three orthogonal axes. Usually, the output rates of IMU measuring angles are not zero, even when the IMU is stationary, and during the IMU measurements the angular products are...
The proper regulation of HCB can improve light conditions within the stand and promote tree growth through tending measures, such as pruning [11,12]. On the other hand, HCB significantly influences the risk and intensity of wildfires’ spread [13,14]. Therefore, effective management of HCB is...
Detailed understanding of landslide susceptibility mapping is important if effective measures against landslides are to be taken. The Kuchisakamoto area in Shizuoka City, Central Japan, has suffered from frequent landslides. Conventional... HP Sato,T Sekiguchi - 《Bulletin Geographical Survey Institute》...
These features were combined with lidar-derived topographic information, and aerial photograph derived texture measures to map 7 forest communities in a portion of the Everglades. An overall accuracy of 71% and Kappa value of 0.64 were produced. We found that low-posting-density lidar data (i.e...
