Influence of Resolution in Irrigated Area Mapping and Area Estimation

Remotely sensed high resolution irrigated area mapping in India for 2000 to 2015

India is among the countries that uses a significant fraction of available water for irrigation. Irrigated area in India has increased substantially after the Green revolution and both surface and groundwater have been extensively used. Under warming climate projections, irrigation frequency may increase leading to increased irrigation water demands. Water resources planning and management in a...

Some New Developments in Small Area Estimation

Small area estimation has received a lot of attention in recent years due to growing demand for reliable small area statistics. Traditional area-specific estimators may not provide adequate precision because sample sizes in small areas are seldom large enough. This makes it necessary to employ indirect estimators based on linking models. Basic area level and unit level models have been extensiv...

estimation of root-zone salinity using saltmod in the irrigated area of kalaât el andalous (tunisia)

in tunisia, kalâat el andalous irrigated district is one of the most affected areas by salinization. the objective of this study was to predict the root zone salinity (over 10 years) in this area using the saltmod simulation model for subsurface drainage system. saltmod is based on water balance, salt balance model, and seasonal agronomic aspects. in the pilot area, irrigated vegetables crops s...

Multi-Resolution Area Matching

In this paper we present a general and robust approach to the problem of close-range partial 3D reconstruction of objects from multi-resolution texture matching. The method is based on the progressive refininement of a parametric surface, which is described using an increasing number of radial functions.
