Modeling Soil–Landscape and Ecosystem Properties Using Terrain Attributes
TL;DR: In this article, a 2-ha hillslope catena in California shows short-distance variation in A horizon depth from 8 to 80 cm and in soil depth between 8 to >450 cm in convex to concave positions.
Journal ArticleDOI
Error in a USGS 30-meter digital elevation model and its impact on terrain modeling
TL;DR: In this article, the authors investigated the potential impact of error in a USGS 30 m digital elevation model on terrain analysis over 27 km 2, and found that these errors had a significant impact on terrain attributes which compound elevation values of many grid cells.

TL;DR: In this article, textural derivatives based on bathymetry from multibeam hydroacoustics with underwater video observations were combined to model and map sessile biota between 10- and 60m water depth over 35 km2 in Point Addis Marine National Park (MNP), Vic., Australia.
