A Geographic Information System (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. It helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared. There are a lot of advantages of using GIS technology. It makes data handling easier, covers large area, used for monitoring various things because of repetitive coverage, it is fast, can be used in inaccessible areas, unbiased, more accurate, reliable and economical. Data could be collected in several bands/ colors so it could be used for micro level analysis. GIS will help in decision making by government officials and in increasing transparency and accountability for good governance. It will help in management of natural resources, improved allocation of resources and planning, improved communication during crisis, cost savings by improved decision makings etc.
The effective use and implementation of Radio-frequency identification (RFID), GPS & data mining techniques in Public Distribution System (PDS) can facilitate PDS supply chain and promise eradicating mismanagement, corruption, trafficking, theft and anti-social elements. RFID provides highly accurate and detailed information by capturing the data and information at each stage of the supply chain, automatically. It also improves the safety and efficiency of the food supply chain. Location technology GPS can also be combined with RFID technology to automatically track and record the information regarding the field where the produce was picked, when and where it was transported and the current location of the produce. This also helps in reducing theft and trafficking. Data mining techniques based on the rule base classification model is used to identify the suspicious moving behavior of the objects.
