OVERVIEW AND CONCEPTS OF GIS

What did you do to reach this Academy?

How you have made your plans? Select certain mode of transport and finding

the Routes to reach Nimora, Answers what/ where and how to reach

Reaching destination (Academy) from Source (District Hq/Block Hq/House) answering locating Nimora (what), finding it’s distance (where) and reaching destination (optimum path)

Understanding GIS (1)

Changes in a period of time

Pattern of relationship

Advances in IT and patterns of human life

Agricultural practice patterns over the times (Example of AP delta regions – single crops before independence, changed to double crops with Nagarjunsagar reservoir. Again changed to prawn culture, mainly due to higher income returns
