High-resolution topographic surveying is traditionally associated with high capital and
logistical costs, so that data acquisition is often passed on to specialist third party …

Agricultural watersheds tend to be places of intensive farming activities that permanently
modify their microtopography. The surface characteristics of the soil vary depending on the …

The monitoring of forest phenology in a cost-effective manner, at a fine spatial scale and
over relatively large areas remains a significant challenge. To address this issue, unmanned …

Observations of plant‐flow interactions on salt marshes have revealed a highly complex
process dominated by the tightly coupled effects of plant characteristics and hydrodynamic …

Understanding dynamic earth surface processes requires various spatial and temporal
information to help produce patterns of landform change. Recent developments in sensor …

Digital elevation models (DEMs) generated from unmanned aerial vehicle (UAV)
photogrammetry offer opportunities for on-demand DEM production in environmental …

This study evaluates the skills of two types of drone-based point clouds, derived from LiDAR
and photogrammetric techniques, in estimating ground elevation, vegetation height, and …

This paper proposes an automatic method for registering terrestrial laser scans in terms of
robustness and accuracy. The proposed method uses spatial curves as matching primitives …

Terrestrial laser scanning is the current technique of choice for acquiring high resolution
topographic data at the site scale (ie over tens to hundreds of metres), for accurate volume …

Sand dunes are commonly regarded as a challenge to traditional photogrammetry due their
homogeneous texture and spectral response. In this work we present an evaluation of …
