Special Issue Information

Dear Colleagues,

LiDAR (light detection and ranging) remote sensing has emerged as a technology that is well-suited for providing accurate estimates of forest attributes in a wide variety of forest ecosystems at a variety of spatial scales. Wildland fires burn millions of hectares every year, and their impacts are of high interest for society, especially in the wildland urban interface.  

The purpose of this Special Issue is to bring together state-of-the-art of remote sensing for forest resource management and wildland fire science. Review papers, technical notes, and research contributions are suitable. In particular, novel contributions covering, but not limited to, the following subtopics described below are welcome:

  • Forest attribute estimation at individual tree and landscape levels using lidar and photogrammetry 3-D derived point cloud data applied to wildfire management;
  • Machine learning and deep learning approaches for estimating forest structure attributes. Fuel mapping and estimation of canopy characteristics across the landscape. Analysis of spatial and temporal changes of vegetation and associated attributes;
  • Use of LiDAR remote sensing data to assess fire/burn severity. Fire effects and post-wildfire landscape change and erosional processes. Quantification of biomass consumption and carbon release;
  • Integration and data fusion approaches using multiple remote sensing data sources to estimate fire progression and burned area. Additionally, fire simulation and fire behavior analysis based on remote sensing data;
  • New methodologies to estimate live and dead fuel moisture content;
  • LiDAR measurements of wildfire smoke over urban environments;
  • Characterization of the wildland fire exposure and risk. Wildfire prevention and planning based on remote sensing technologies;
  • Synergies among platforms (airborne, terrestrial, and spaceborne) for forest inventory and monitoring.

The leaf area index (LAI) is a crucial structural parameter of forest canopies. Light Detection and Ranging (LiDAR) provides an alternative to passive optical sensors in the estimation of LAI from remotely sensed data. However, LiDAR-based LAI estimation typically relies on empirical models, and such methods can only be applied when the field-based LAI data are available. Compared with an empirical model, a physically-based model—e.g., the Beer–Lambert law based light extinction model—is more attractive due to its independent dataset with training. However, two challenges are encountered when applying the physically-based model to estimate LAI from discrete LiDAR data: i.e., deriving the gap fraction and the extinction coefficient from the LiDAR data. We solved the first problem by integrating LiDAR and hyperspectral data to transfer the LiDAR penetration ratio to the forest gap fraction. For the second problem, the extinction coefficient was estimated from tiled (1 km × 1 km) LiDAR data by nonlinearly optimizing the cost function of the angular LiDAR gap fraction and simulated gap fraction from the Beer–Lambert law model. A validation against LAI-2000 measurements showed that the estimates were significantly correlated to the reference LAI with an R2 of 0.66, a root mean square error (RMSE) of 0.60 and a relative RMSE of 0.15. We conclude that forest LAI can be directly estimated by the nonlinear optimization method utilizing the Beer–Lambert model and a spectrally corrected LiDAR penetration ratio. The significance of the proposed method is that it can produce reliable remotely sensed forest LAI from discrete LiDAR and spectral data when field-measured LAI are unavailable. Full article
