We present a practical approach to inter-compare range of candidate digital elevation models (DEMs) based on pre-defined criteria and statistically sound ranking approach. The presented integrates the randomized complete block design (RCBD) into novel framework for DEMs comparison. method provides flexible, customizable tool evaluating quality any raster - in this case DEM by means approach, which takes account confidence level, can use both quantitative qualitative criteria. users their own...
This paper illustrates the main results of a statistical analysis performed on data set obtained by integrating experimental observations collected during many oceanographic research projects northern Adriatic Sea (NAS). The cover last 20 years and provide robust base for assessment current state scales variability temperature, salinity, nutrients, dissolved oxygen, chlorophyll. confirmed clear seasonal cycle marked spatial gradients most parameters in all seasons. largest proportion river...
Abstract. Surface texture analysis applied to high-resolution digital terrain models (HRDTMs) is a promising approach for extracting useful fine-scale morphological information. roughness, considered here as synonym of surface texture, can have discriminant role in the detection different geomorphic processes and factors. Very often, local morphology presents, at scales, anisotropic characteristics that could be taken into account when calculating or measuring roughness. The high detail...
Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) techniques are gaining momentum in the assessment and health monitoring of infrastructure assets. Amongst others, Persistent Scatterers Interferometry (PSI) technique has proven to be viable for long-term evaluation ground scatterers. However, its effectiveness as a routine tool certain critical application areas, such millimetre-scale differential displacements airport runways, is still debated. This research aims...
At least 10 global digital elevation models (DEMs) at one-arc-second resolution now cover Earth. Comparing derived grids, like slope or curvature, preserves surface spatial relationships, and can be more important than just values. Such comparisons provide nuanced DEM rankings root mean square error (RMSE) for a small number of points. We present three new comparison categories: fraction unexplained variance (FUV) grids with continuous floating point values; accuracy metrics integer code...
In this study, we investigate the surface flow time of rise in response to rainfall and snowmelt events at different spatial scales main sources originating channel runoff spring water a steep nested headwater catchment (Rio Vauz, Italian Dolomites), characterized by marked elevation gradient. We monitored precipitation elevations measured stage/streamflow outlet two rocky subcatchments same size, representative upper part dominated outcropping bedrock, soil-mantled vegetated subcatchment...
Abstract. Herein, an aerial LiDAR topographic dataset is analysed and interpolated by means of geostatistical techniques in order to examine the morphology a scree slope area Eastern Italian Alps. The LiDAR-derived digital terrain model (DTM) using variogram maps as spatial continuity indexes. This allowed for evaluation reproduction variability topography characterization comparison different morphological features occurring study site. results indicate that efficiently synthesise local...
Abstract. High-resolution topographic data expand the potential of quantitative analysis earth surface, improving interpretation geomorphic processes. In particular, morphologies channel beds mountain streams, which are characterised by strong spatial variability, can be analysed much more effectively with this type data. study, we aerial LiDAR a headwater stream, Rio Cordon (watershed area: 5 km2), located in Dolomites (north-eastern Italy). The morphology bed is alternating step pools,...
High-resolution digital terrain models (HR-DTMs) of regional coverage open interesting scenarios for the analysis landscape, including derivation and channel network. In this study, we present network from a HR-DTM Autonomous Province Trento. A preliminary automatic extraction raw was conducted using curvature-based algorithm applied to 4 m resolution DTM derived an airborne LiDAR survey carried out in 2006. The automatically extracted underwent supervised control check spatial pattern...

Geostatistical methods are well suited for analyzing the local and spatial uncertainties that accompany modeling of highly heterogeneous three-dimensional (3D) geological architectures. The 3D hydrogeological architectures is crucial polluted site characterization, in regards to both groundwater planning remediation procedures. From this perspective, Porto Marghera, located on periphery Venice lagoon, represents an interesting example. For site, available dense sampling network, with 769...
Hypsometric curves and integrals are effective tools for rapid quantitative assessments of topography.
