What is Open Source • Open source is a development method for software that harnesses the power of distributed peer review and transparency of process. The promise of open source is better quality, higher reliability, more flexibility, lower cost, and an end to predatory vendor lock-in. (From opensource. org) 2

So What About Open Source? Four basic freedoms : The freedom to run the program, for any purpose. The freedom to study how the program works, and adapt it to your needs. The freedom to redistribute copies so you can help your neighbour. The freedom to improve the program, and release your improvements to the public, so that the whole community benefits. Why are they using it? Often free with no up front and recurring fees Anyone that can’t afford proprietary software Ability to improve/contribute Collaborative, community-based software development process 3

Users can directly manipulate maps and GIS data over the Web. GIS can easily incorporate up-to-date, real-time information There are many Open Source software available for Web. GIS purpose such as Map. Server, Geo. Server, Degree etc. 5
