ModEco is a software package for ecological niche modeling. It integrates a range of niche models within a geographical information system. ModEco provides a user friendly platform that enables users to explore, analyze, and model species distribution data with relative ease. It contains a suite of functions such as data input/output, data visualization, feature analysis, […]
Geographic One-class Data: Methods & Applications
Geographic One-class Data: Methods & Applications We are interested in the theory and applications of geographic one-class data. One common problem with geographic data is that, for a specific geographic event, only occurrence information is available; information about the absence of the event is not available. We define these specific types of geospatial data as […]
Development of near-surface remote sensing platforms
Development of Near-surface Remote Sensing Platforms for Forest Resource Information Acquisition Light detection and ranging (lidar), an active remote sensing technology, has the abilities of high-precision and strong penetration to vegetation, which shows unparalleled advantages in obtaining forest resource information comparing with other traditional remote sensing technologies. In this context, we designed and developed a […]
3D Forest Structure: Parameter Extraction & Upscaling
3D forest structure parameter extraction and upscaling Individual trees are the basic element composition of a forest stand. The structure characteristic and spatial distribution of trees are the key factors to be surveyed in forest inventory. Lidar, as an emerging active remote sensing technology, provides an automatic, effective and accurate tool for deriving individual tree […]
Spatial & Temporal Monitoring: Forest Resource Analysis
Monitoring and analyzing the spatial and temporal changes of forest resource information Changes of forest quality are composed by the changes in forest structure and species composition, which are usually caused by tree growth, anthropogenic activities (e.g., forest treatment, logging), and environmental disturbances (e.g., drought, flood, and wildfire). To quantitatively assess forest structure changes from […]
High-throughput Crop Phenotyping: Development & Application
Development and application of high-throughput crop phenotyping platform Phenomics studies the external performance of crop traits under the interaction of genes and the environment, which provides a new way for crop breeding. The current development of phenomics is far behind the development of genomics due to the lack of high-throughput phenotype platforms and algorithms. In […]
Mapping the new generation Vegetation Map of China-1
Vegetation maps provide crucial information for ecological studies, biodiversity conservation, vegetation management and restoration, and national strategic decision making. The current vegetation map of China was produced by a team of more than 250 scientists over the course of two decades starting in the 1980s, who spent a huge amount of efforts to manually delineate […]
Forest tree height across the Sierra Nevada-1
Forests of the Sierra Nevada (SN) mountain range are valuable natural heritages for the region and the country, and tree height is an important forest structure parameter for understanding the SN forest ecosystem. There is still a need in the accurate estimation of wall-to-wall SN tree height distribution at fine spatial resolution. In this study, […]
Global mangrove forest AGB map-1
Mangrove forest ecosystems are distributed at the land–sea interface in tropical and subtropical regions and play an important role in carbon cycles and biodiversity. Accurately mapping global mangrove aboveground biomass (AGB) will help us understand how mangrove ecosystems are affected by the impacts of climatic change and human activities. Light detection and ranging (LiDAR) techniques […]
Benchmark dataset for airborne lidar scanning data filtering in forested environments-1
Data description: Airborne laser scanning (ALS) data is one of the most commonly used data for terrain products generation. Filtering ground points is a prerequisite step for ALS data processing. Because canopy cover and terrain slope are various in forested environments, filtering in forested environments is more challenging than filtering in other environments, such as […]
