Irrigation land suitability assessment and mapping play an imperative role for sustainable utilization of scarce physical land resources. The objectives of this study were to prepare spatial data base of physical land resources for irrigated agriculture and to assess land suitability for irrigation and developing suitable area map for the study area. The study was conducted at Fogera catchment,...

This paper briefly describes the status of Temperature and Chlorophyll-a trend in Kalpakkam Coast, discusses its ecological and temperature impacts recommending measures to achieve long term sustainability using advanced tools like Geographic Information System (GIS). Present study reveals the monthly spatial distribution of Temperature and Chlorophyll-a at Kalpakkam. Transect based in-situ Tem...

This is the ®rst of two papers that elaborate an integrated drainage network analysis system (IDNAS) for agricultural drainage management. In this paper, the system components, functions and implementation are presented. The IDNAS comprises an agricultural drainage network module, an evapotranspiration (ET) module and an event-based spatio-temporal module. The network module is designed to mode...

The problem of carbon dioxide in several cities Indonesia is getting higher and requires more focused handling. city Tegal, one the located on Pantura route, has a significant impact distribution CO2 emissions. This research was conducted by modeling mapping number emissions roads based outcomes transportation efforts Tegal City. Arc-GIS used for analysis modeling, with an approach to calculati...

In this study, a hybrid GIS-supported watershed modelling system is developed for integrated planning of water pollution control in the Lake Erhai basin, China. The system comprises a GIS-supported database, simulation/optimization models, and user interfaces developed through Arc/Info and ArcView. An inexactfuzzy multi-objective optimization model is developed for assessing a variety of system...

A high-speed earthing switch (HSES) of a gas-insulated switchgear (GIS) performs a secondary role in protecting the power system in the event of an accident. After being interrupted by a circuit breaker (CB), the short-circuit current remaining in the network should be earthed by the HSES. However, as the contacts of the HSES may have been damaged by a pre-arc during the closing operation, the ...

This paper presents a novel divide-and-conquer method to analyze spatial information, such as geometric shapes, contours and trajectories extracted as a discrete sequence of points (or pixels) from images or spatial sensors, including GPS or transponders. The method extracts contour point sequences and then uses a scale invariant analysis to extract invariant arc features. The arc feature is a ...
