Analysis of mobile laser scanning data and multi-view image reconstruction [PDF]
, 2012 The combination of laser scanning (LS, active, direct 3D measurement of the object surface) and photogrammetry (high geometric and radiometric resolution) is widely applied for object reconstruction (e.g. architecture, topography, monitoring, archaeology)

Exploring Costa Rica's fungal trends: Insights from digitized specimens
PLANTS, PEOPLE, PLANET, EarlyView.Fungi are essential to tropical ecosystems but remain largely absent from conservation agendas. By analyzing over 78,000 fungal records from Costa Rica—a globally recognized biodiversity hotspot—this study reveals key patterns in fungal diversity, distribution, and seasonality.

ROBUST AND ACCURATE IMAGE-BASED GEOREFERENCING EXPLOITING RELATIVE ORIENTATION CONSTRAINTS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 Urban environments with extended areas of poor GNSS coverage as well as indoor spaces that often rely on real-time SLAM algorithms for camera pose estimation require sophisticated georeferencing in order to fulfill our high requirements of a few ...

Climate change‐driven expansion of goosegrass highlights risks to global food production
Pest Management Science, EarlyView.Climate change is expanding the climatic suitability of Eleusine indica into temperate agricultural regions, increasing its overlap with major soybean and maize production areas. These findings highlight a growing global threat to food security and the need for proactive weed management strategies.

Using Fine Sediment Monitoring to Quantify Sand Loading Over Time
River Research and Applications, EarlyView.ABSTRACT Riverine sand loading can lead to geomorphic change, impacting river processes like lateral migration and vertical aggradation or degradation. Yet many sediment monitoring programs track only fine sediment measurable as total suspended solids (TSS). Here, we assess the ability for TSS data to be used to determine sand loading.

Eelgrass Distribution in the Great Bay Estuary and Piscataqua River for 2017 [PDF]
, 2018 Eelgrass distribution in Great Bay, Little Bay, and the Piscataqua River Estuary was mapped from aerial photography acquired on August 24, 2017. The total area of eelgrass beds with 10% or greater cover and a polygon area equal to or greater than 100 ...

Using time‐series remote sensing to identify and track individual bird nests at large scales
Remote Sensing in Ecology and Conservation, EarlyView.Time‐series airborne imagery can potentially track individuals over time to collect information beyond one‐off counts. Using weekly UAS‐based imagery of wading bird colonies, we develop an automated approach to identifying nests. Our algorithmic approach detected 68–74% of known nests and exhibited similar performance to human review of imagery ...
