Speak friend, teaching remote sensing and GIS in an r A engineering college, invited me to deliver a lec- o ture on 'Remote Sensing Applications - Industry t Perspective' to his students. His reasoning was that i being attached to industry, I could give a practical view as opposed to the bookish view. As I began preparing d for the talk, I realised that there was a fundamental E flaw in the title. It was not possible to isolate remote sensing from other technologies if I was to address applications of a practical nature. For example, if I tried to illustrate the use of high resolution data for land records, I could not ignore differential GPS which would give me the data to correctly register the plot boundaries to the imagery. Again, the use of imagery for precision farming and agri-business has to include GPS, GIS and data related to prices, inflation and oth- er economic factors. In fact remote sensing is only one of the data sources, an important one though not the only one. Prof. Arup Dasgupta Managing Editor Imagery becomes the starting point. To this we have to [email protected] add value by extracting information required for the end user. To enable more people to be able to use satellite imagery, satellite data providers are moving access. More importantly it will be available in a form from selling imagery to providing information and required by the user. Thus, a user needing the NDVI of insight to customers. This has tremendous impact in a particular area will be directly served the NDVI many ways. Data buyers are aware of the storage image and not the multiple band imagery. I believe issues. Back in the 80's, data used to come in tapes this will be a great boon to users who currently spend and it was a daunting task to ensure their longevity by a considerable amount of time, energy and money just storing them in climate controlled environments.
