Web-based G.I.S and Mapping Course

INTRODUCTION

Web mapping focuses on disseminating and processing geographic information by means of Internet and World Wide Web. Combination of the web and GIS (Geographic Information Systems) has unlocked the potential of GIS, and put online maps and geospatial intelligence in the offices/homes of millions and the hands of billions. The increasing flexibility and interoperability of web mapping technologies has opened new opportunities for Web Based Mappers.

Both non-GIS users and GIS experts can do more now, than ever to share maps over the internet. Web maps can easily deliver up to date information,maps are generated automatically from databases, and they can display information in almost real-time. They don't need to be printed, mastered and distributed. Web GIS has immense applicability to e-government, e-business, e-science, and all aspects of daily life. Government employees can utilize Web GIS to improve public services delivery and boost collaboration across agencies.Regardless of the sector, businesses can use Web GIS to enhance their existing business models and create new ones. Researchers can find new solutions to meet the challenges of the new frontiers. Web GIS has great practical value to our world today and into the future.
