Abstract

Remote Sensing and Geographical Information Systems are two technologies that, although thought to be similar, have very different origins, and possibly the output of one technology could be input to the other. With the Government of India taking unprecedented interest and measures in using these technologies for development and governance, these are now rapidly growing fields, indicating that geospatial science and technology will be central for information management and dissemination. And yet, these fields are struggling to have a strong presence in the country. There are several misnomers regarding GIS and remote sensing. One misnomer is that both technologies are synonyms, while another common mistake is that the two fields are just software such as QGIS. This article attempts to describe the two different technologies in straightforward terms while explaining the differences between the two. The two technologies have independent existence and thus, associated applications. We describe the basic concepts and current advancements in both technologies with specific examples. We also indicate possibilities on how the two technologies can be integrated and used together for decision making. This article draws attention to the fact that though these disciplines are closely related, and much effort has gone into keeping them easily accessible, it is vital that other disciplines that are utilizing them respect the differences, understand the specific technical expertise required for each, and thus value the unique capabilities each of them brings.
