Topographic measurements are essential for the study of earth surface processes. Three‐dimensional data have been conventionally obtained through terrestrial laser scanning or photogrammetric methods. However, particularly in steep and rough terrain, high‐resolution field measurements remain challenging and often require new creative approaches. In this paper, range imaging is evaluated as an alternative method for obtaining surface data in such complex environments. Range imaging is an… 

Geo-referenced mapping using an airborne 3D time-of-flight camera

This paper presents the first experience of a close range bird's eye view photogrammetry with range imaging (RIM) sensors for the real time generation of high resolution geo-referenced 3D surface

Field application of close‐range digital photogrammetry (CRDP) for grain‐scale fluvial morphology studies

In situ measurement of grain‐scale fluvial morphology is important for studies on grain roughness, sediment transport and the interactions between animals and the geomorphology, topics relevant to

Investigating the geomorphological potential of freely available and accessible structure‐from‐motion photogrammetry using a smartphone

Results for the river bank survey demonstrate that centimetre-precision DTMs can be achieved at close range (10 m or less), using a smartphone camera and a fully automated package, and improve to sub-centimetre precision with either higher-resolution images or by applying specific post-processing techniques to the smartphone DTMs.


This work aims at investigating the use of a low cost Time of Flight camera, combined with an Ultra-Wide Band (UWB) positioning system, mounted on a drone, in order to enable quasi real time 3D reconstructions of small to mid-size areas, even in locations where Global Navigation Satellite Systems (GNSSs) are not available.

Abstract. The ground resolved distance (GRD) of an imaging sensor, i.e. the size of the smallest element distinguishable on acquired imagery, is one of the most important sensor quality assessment

Dem Measurements of A Gravel‐Bed Surface Using Two Scales of Images

Determining the geometry of an exposed gravel‐bed surface is important in understanding river flow characteristics. This study presents a method of generating a digital elevation model (DEM) of



Through‐Water Close Range Digital Photogrammetry in Flume and Field Environments

Measurement of the structure of gravel‐bed river surfaces is crucial for understanding both bed roughness and the sediment entrainment process. This paper describes the use of close range digital

Towards a protocol for laser scanning in fluvial geomorphology

Advances in spatial analytical software allow digital elevation models (DEMs) to be produced which accurately represent landform surface variability and offer an important opportunity to measure and

Photogrammetric monitoring of small streams under a riparian forest canopy

The recent advent of digital photogrammetry has enabled the modeling and monitoring of river beds at relatively high spatial resolution (0·01 to 1 m) through the extraction of digital elevation

Measuring streambed morphology using range imaging

Characterizing streambed morphology is crucial to better understand fluvial systems, since the streambed is an important control on stream dynamics, particle motion and bed stability. There is a lack

Towards a protocol for laser scanning of rock surfaces

The precision of height measurements derived from laser scanning a weathered rock surface was analysed. Different registration methods for comparing surfaces to deduce weathering were assessed and

In situ characterization of grain‐scale fluvial morphology using Terrestrial Laser Scanning

The grain‐scale morphology of fluvial sediments is an important control on the character and dynamics of river systems; however current understanding of its role is limited by the difficulties of

Small format digital photogrammetry for applications in the earth sciences

Photogrammetry is often considered one of the most precise and versatile surveying techniques. The same camera and analysis software can be used for measurements from sub-millimetre to kilometre

Accuracy of high‐resolution photogrammetric measurements of gullies with contrasting morphology

Field techniques allow accurate direct measurements on gully geometry, even in three‐dimensional (3D) coordinates. Accuracy and detail reproduction is limited mainly by experimental setup and density

Aerial photosieving of exposed gravel bars for the rapid calibration of airborne grain size maps

In recent years, fluvial remote sensing has seen considerable progress in terms of methods capable of system scale characterisation of river catchments. One key development is automated grain size
