Sentence examples for derived topographic from inspiring English sources

Boosted regression trees, an ensemble classification and regression algorithm, was used to compare tree species abundance models that included LiDAR derived topographic variables with models that included spectral and LiDAR derived topographic and vegetation variables.

To evaluate the role of regolith thickness on earthquake induced building damage, a remote sensing based methodology is developed to model the spatial variation of regolith thickness, based on DEM derived topographic attributes and geology.

Tectonically derived topographic anisotropy is associated with the three-dimensional kinematic field, which contributes (1) differential surface displacement and (2) crustal weakening along fault structures, both of which amplify processes of surface erosion.

We created an indicator of potential wetland areas (PWA), using nationally available datasets to identify characteristics that could support wetland ecosystems, including: poorly drained soils and low-relief landscape positions as indicated by a derived topographic data layer.

This study provides both external and internal accuracy assessments for the derived topographic models (note that different data sets are used, albeit independent).

We derived topographic characteristics for the 800 m grid cells of analysis from the 30 m National Elevation Dataset (Gesch 2007) using SAGA GIS version 2.1.0 (www.sagagis.org).org

Poor relationships were found when using a good quality medium resolution digital elevation model to derive topographic factors.

Digital elevation models are readily available for deriving topographic attributes; also sensor digital data can be used to indirectly assess cover crop biomass.

The objectives of this study are to examine how relationships between cover crop biomass, assessed using the normalized difference vegetation index (NDVI), and topography depend on the neighborhood size used for deriving topographic attributes and creating NDVI maps; and identify the optimal neighborhood size for correlation and regression analyses.

Most previous studies have processed the imagery and laser altimeter data separately for lunar topographic modeling, and there are usually inconsistencies between the derived lunar topographic models.

These are typically very detailed products (with a small footprint on the ground) and provide much more topographic information than from Digital Elevation Models (DEMs) that were derived from topographic maps.
