Crop growth and productivity are determined by a large number of weather, soil and management variables, which vary significantly across space. Remote Sensing (RS) data, acquired repetitively over agricultural land help in identification and mapping of crops and also in assessing crop vigour. As RS data and techniques have improved, the initial efforts that directly related RS-derived vegetatio...
Irrigation is the artificial application of water to crops supply moisture. With rising drought indices and rapid population expansion, need for irrigation food production growing. Nonetheless, irrigated agriculture battling several issues that have resulted in poor performance, inefficient usage, low crop production. Improving use efficiency necessitates using technology decreases losses, matc...

The use of new methods of Remote Sensing (RS) and Geographical Information System (GIS) in zoning the flooding potential and its variations in a particular geographical area (Tang-e-Bostanak Catchment Area) constitutes the main subjects of this study. In this regard, the production, combination, and composition of effective information layers such as K index and run off in identifying these zon...
Changes in river plane shapes are called river planform changes (RPCs). Such changes can impact sustainable human development (e.g., human habitations, industrial and agricultural development, and national border security). RPCs can be identified through field surveys—a method that is highly precise but time-consuming, or through remote sensing (RS) and geographic information system (GIS), whic...
In geomorphology there are variety methods to separate and identify the formic units. One of them is Hierarchy Theory. In this paper study area is Gavkhoni Playa. The purpose of this study is to identify separation and display formic units by using GIS and RS techniques hierarchically. To achieve this aims, topographic maps (1:25000, 1:50000), geological map (1:250000), satellite image of senso...

abstract this research was conducted in the pegah - sorkh sub-catchments area, a semi-arid region in sw iran, using geographic information systems (gis) and remote sensing (rs) to compare the erosion potential method (epm) and modified pacific southwest interagency committee (mpsiac) models in erosion-potential mapping and sediment yield assessment. the study area with approximately 4600 ha sho...
Abstract In agriculture management and cultivation, many researchers tend to introduce implement new methods or techniques improve the sectors in order sustain a good production from sectors. The oil palm plantation is one of that have received an improvement development aspects. Thus, this paper reviews detail recent expansion sustainability through latest application technologies specifically...
