An Automated Method for Digitizing Color Thematic Maps
There is an increasing need for methods of rapidly entering analog data into geographic information systems. Traditional methods of hand digitizing or hand tracing followed by scanning are costly and time consuming. We have developed a rapid, easy to use method for digitizing color thematic maps that makes use of standard image processing techniques. The method uses a digital camera followed by...
متن کاملIdentification of Groundwater Potential Zones in Moalleman, Iran by Remote Sensing and Index Overlay Technique in GIS
Water plays a vital role in the development of activities in an area. The surface water resources are inadequate to fulfill the water demand. Productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. Keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...

متن کاملDemarcation of Groundwater Prospective Zones in Humid Tropical River Basin: A Geospatial Approach
Groundwater, being a vital resource, needs to be developed with proper understanding about its occurrence in time and space. Unscientific sand mining is a dominant environmental issue in this humid tropical river basin namely Bharathapuzha river basin geographically on central part of Kerala state, southwest part of India. The sandy layers along the river course declines its water holding capac...
متن کاملSpace Vector Modulation Based on Classification Method in Three-Phase Multi-Level Voltage Source Inverters
Pulse Width Modulation (PWM) techniques are commonly used to control the output voltage and current of DC to AC converters. Space Vector Modulation (SVM), of all PWM methods, has attracted attention because of its simplicity and desired properties in digital control of Three-Phase inverters. The main drawback of this PWM technique is 
its complex and time-consuming computations in real-time ...
