Elucidating the mashup hype
The idea behind creating a live feed is to benefit a student by giving an alert to his or her e-mail or mobile phone as the site gets updated.Good web scraping techniques and tools exist for such kind of implementations.GIS and mapping applications have both benefited from and contributed to these trends, collectively called “Web 2.0”.
The website puts up information on a web notice board for its students to know the details regarding notifications, examination schedules and other required information as shown in fig-2.
The information as such is presented in HTML form and a student is expected to visit the web site often to get to know about an update.
It was found to be more intuitive in using the frame-work.
Simple steps were followed in setting the spatial reference system, adjusting the back ground layer to the required extents and then uploading the layers as shape files to the service.
The service quickly added them as layers on top and followed with steps for adjusting the layer style settings.
Finally the map could be published either through making it available for public viewing, create an online web application or a through a link that could be used for hosting on user’s own web server as shown in fig-1.These spatially aware methods and applications require little or no programming expertise, and show that with the modern web, it”s all about location, location, location.And for those that know a little bit of web scripting, map mash-ups with mapping tool APIs have considerable power to integrate data from multiple sources onto an online map.The objective of attempting this task was to create useful feeds as standard RSS /JSON or other formats from static websites.In this regard the Website of Jawaharlal Nehru Technological University, Hyderabad ) was chosen to extract required information and generate a live feed.There exist several data providers that render geo-spatial data depicting the entire world in an extremely fast rendering on-line application within a web browser.
