Hi Ravi, sorry about the late reply, but maybe some of the presentations and reports we have on the OA Digital website will provide some useful material/arguments for you:
http://www.oadigital.net/research Current GIS software, proprietary or open source, has so much functionality that you can always make one or the other look like the "winner", depending what application area you focus on. At OA Digital, we have tried to focus on arguing three strong points that open source solutions have, no matter what the particular features may be: 1. Economic suistanability: licensing fees have no merits for the customer past their expiration date. Once that is reached, all former investment is automatically invalidated. On the other hand, investing into open source development and staff skills instead of licenses has long-term merits and is suistanable. 2. Modular functionality: it's all there. If not in one package than via a combination of several. If something is still missing: hire a programmer to add it. It's also really easy to build automatic, very efficient data processing workflows from small open source components using scripts etc. 3. Interoperability: it's really easy to exchange data among open source applications, because they respect open standards and don't drop older file formats just to force customers to upgrade. By contrast, proprietary applications just try to lock you into them by using undisclosed file formate (so called "vendor lock-in"). This is one of the most important points, because the future of GIS is in spatial data infrastructures (SDI), where the data is at the centre of all planning and management and the GIS applications become more and more interchangeable. Hope this will provide some support arguing your points for open source software. You have to realize that the big GIS vendor (let's not kid ourselves: there really is just one and they have a suffocating monopoly on the market) will have about 1000 x the resources to put into marketing, brochures, shiny packages, lobbying and high-ranking political connections. So this is always an uphill struggle, no matter how clear the open source advantages are to the informed mind. Good luck!
