The paper describes the development of a spatial modeling language and visualisation environment that simulates landscape processes. The virtual reality modeling language (VRML) is evaluated as a suitable technology for visualising landscape models. Examples for water runoff and landform evolution are given. D.

Many biochemical processes and dynamics are strongly controlled by terrain topography, making digital elevation models (DEM) a fundamental dataset for range of applications. This study investigates the quality four pan-Arctic DEMs (Arctic DEM, ASTER ALOS DEM Copernicus DEM) within Kalix River watershed in northern Sweden, with aim informing users about when comparing these DEMs. The assessment ...

There are two challenges in classifying lidar points into ground and non-ground points on Texas coastal areas, which usually has a low-lying landform consisting of morphological features including dunes, tidal and river channels with levees, barren flats, buildings, and trees with varying cover density. The first is to remove buildings and trees meanwhile keeping seawall, dunes, levees and chan...

Terrain is generally stored in GIS as an elevation field, whereas human cognition of the landscape is usually object based. To address this mismatch of terrain data models, we propose object-based terrain representation, using topographic eminences, which are landforms that rise up conspicuously from the ground to visibly dominate the landscape, to illustrate our case. We propose a cognition ba...

The area of the Inner Asian Mountain Corridor (IAMC) follows foothills and piedmont zones around northern limits Asia’s interior mountains, connecting two important areas for human evolution: Fergana valley Siberian Altai. Prior research has suggested IAMC may have provided an connected refugia from harsh climates during Pleistocene. To date, this region contains very few secure, dateable Pleis...

This research paper provides an in-depth analysis of the geographical landform types found in Uttar Pradesh, encompassing its diverse topography, river systems, plains, hills, and other notable features. Through a comprehensive study geological history, climate, environmental factors, this aims to offer overview landforms that define Pradesh's distinctive geography.
