A cost effective, reproducible and reliable system of classification of landscapes into homogeneous units characterizing land based on its physical, biological and cultural characteristics -denoted as Land Management Units (LMUs) is of significant importance for management and planning purposes. Especially for developing countries, LMU systems are very critical as they aid in decision making pr...

despite of suitable geological and climatic conditions for forming and evolution of alluvial fans and importance of this landform as soil and water resources in arid regions, there are limited studies about this landform in iran. in the present study, evolution and pedogenic development of geomorphic surfaces of an alluvial fan in eastern isfahan were studied by using remote sensing, field and ...

In this work we presented a methodology based on non linear regression for Landform Attributes representation. The equations to estimates the parameters of a two dimensional polynomial are shown and, for testing the methodology, it was used the data of Landform Attributes from the state of Minas Gerais (Brazil) obtained by the Digital Model of Elevation (DME) from GTOPO30 [5] project, in the fo...

− This paper examines the use of different classifiers for integrating multi-temporal remotely sensed data with landform data derived from digital elevation models to produce maps showing areas affected by salinity in the south west agricultural region of Western Australia. Decision trees are used to map saline areas in the Ryan’s Brook catchment, located approximately 50 kilometres southwest o...

Aim Land-use history can be an important determinant of ecosystem characteristics, even in landscapes that outwardly appear natural . In New England, like much of the eastern United States, the natural reforestation of agricultural lands over the past 150 years has created a predominantly forested landscape. Understanding the physiographical and historical factors controlling forest structure a...
