Development of national extent terrain attributes (TANZ), soil water balance surfaces (SWatBal), and environmental surfaces, and their application for spatial modelling of Pinus radiata productivity across New Zealand
… surfaces include 15 primary and four secondary terrain attributes; 13 shortwave radiation surfaces, topographically adjusted (one annual and 12 monthly surfaces); and 39 soil water balance model surfaces (one annual and 12 monthly surfaces for fraction of available root zone water storage, …

Effects of dynamic vegetation and topography on hydrological processes in semi-arid areas
… dynamics occurring in the complex terrain of a semi-arid area characteristic of central New Mexico. The study constructs a dynamic model of coupled interactions, [tRIBS+VEGGIE], that considers essential water and energy processes over the river basin and links them to the basic …

Spatial Variability of Corn Response to Nitrogen Fertilizer: Implications for Variable Rate Fertilization
… nitrogen fertilization were developed based on terrain attributes, the ISNT and nitrogen fertilizer as independent variables. The site-specific characteristics interacted with nitrogen fertilizer indicating that they affect corn response to nitrogen fertilizer application and that corn response …

Analysis of microtopography, vegetation, and active-layer thickness using terrestrial LIDAR and kite photography, Barrow, AK
… on microtopographical variations derived from terrain attributes including elevation, slope, and Melton’s Ruggedness Number (MRN). Landcover at each plot was classified using the Visible Vegetation Index (VVI), calculated from a series of high-resolution (~10 cm) kite photographs obtained in …

Bedrock target analysis for ROV rockdrill sampling and existing sample stratigraphic and mineralogical verification (BeTar_drill)
… escarpments and submarine canyon systems. This terrain is exemplified on the Irish Atlantic Margin (IAM) by the Porcupine Bank Canyon (PBC). Bedrock has been found here in the past, however, surveying in these areas continues to be a difficult task due to issues regarding access and sampling …

Impacts of forest harvesting on the performance of soil-landscape modelling in a radiata pine forest, northern New Zealand
… between the target properties and the terrain attributes ( derived from a 5-m digital elevation model) were described using the squared-multiple-correlation statistic. The soils of southern Mahurangi Forest differ predominantly in terms of soil drainage condition. A modified version of …

Wetland landscape dynamics and its socio-ecological implications
… The second part involved deriving secondary terrain attributes using the compound topographic index (CTI) and the stream power index (SPI) generated from the United States Geological Survey (USGS) digital elevation model (DEM). The third part involved metric calculations, which were …

Soil-Landscape Modelling in an Andean Mountain Forest Region in Southern Ecuador
… by means of statistical models relating soil to terrain attributes, i.e. predictive soil mapping. A 24 terrain classes comprising sampling design for soil investigation in mountainous areas was developed to obtain a representative dataset for statistical modelling. The soils were investigated by …
