Hi Srinadh,
The increased use of geospatial technology in different industries has improved the scope of job opportunities in GIS and Remote Sensing. Every area ranging from missile and unmanned aerial vehicle technology to urban administration, e-governance, and remote sensing and even advertising and marketing today depend on geospatial data.
The skills required to be a successful GIS professional changed and evolved over the years. Though an elective of the civil engineering stream, it can also be taken up by the students of other subjects, especially geography and geology, as a specialization. There are a number of career opportunities in this field, both in India and abroad. Thus, candidates from a wide variety of professional and educational backgrounds (e.g. Geography, Urban Planning, Cartography, Engineering, Computer Science and so on) aspire to be successful GIS professionals.

Dear Madhu!
In India, MBA is not offered in Data Science. Since it's more of a technical course, you can pursue M.Tech in Data Science. However, there are many people who are self-taught. So in this way, you too can be one.
Start with learning Maths & Stats. Go ahead with Programming (Python & R), Data Mining, Manipulation, Analytics, Visualisation, etc. as parts of Data Analysis. Further, you can explore more in Machine Learning, Deep Learning, Natural Language Processing and hence Artificial Intelligence to be a Data Scientist.
Madhu, it's a very vast, complicated but promising field. You need to stay focused, consistent, brilliant to be in this field. In addition to this, also look out for your communication skills a lot, as it helps a lot in this sector.
Hope this helps. Upvote the answer if you feel satisfied. Good luck.
