A Little Insight to Community based GIS applications.
We live at a time when information is
a vital commodity. But the value of any information is determined by
timeliness, accessibility, and by our ability to understand and use it.
Internet has become a remarkable platform which empowers people, by satisfying
any kind of information need on user demand. Spatial data has become one such
highly demanding information need and internet provides a unique platform to
distribute them. The growth of the internet and increasing demand for
geospatial data in various social streams, have lead the way to popular
Geographic Information Systems to appear over the past decade.
One such application is foursquare which is a mobile and web
application, that allows its registered users to post their location at a venue
and connect with friends. This will be appeared as a “check in” and it needs
active user selection. Each check in will be awarded with points and users can
choose to post them on Facebook or twitter or on both of them. When a user
checked into various places, foursquare will offer badges also. Foursquare
comes with three user levels to rank the registered users on their contribution
to the community.
- Super user level 1 can edit venue info (name, address, cross street, phone, Twitter names, and map pin location), mark venues as open or closed, request venue merges and deletions, and edit venue tags.
- Super user level 2 can additionally merge duplicate venue listings, adjust the latitude and longitude of a venue, add a web address, and add categories.
- Super user level 3 adds the ability to create and remove venue aliases, as well as access a "global queue" of pending requests needing super user attention.
Foursquare has some marvelous functionalities such as allowing users to create to do lists including the places they want to visit. With their latest release which is foursquare 4.0, they have introduced a new feature called “Radar”. Radar is capable of giving notifications to the user, when he or she is close to a place that’s either on their to-do list or another list they follow or when three or more friends have checked in to a nearby venue.
Foursquare has its own API, so that developers are encouraged to build new applications for foursquare and that may be another reason for their day by day growing popularity. “Where do you go”, “Peek maps”, “Black Book”, “Last Night’s checkins” are some of the applications build upon foursquare API. Foursquare supports for many languages all around the world namely, French, Italian, German, Spanish, and Japanese, Indonesian, Korean, Portuguese, Russian and Thai. It has been released to almost all the popular smart mobile platforms such as Android, Symbian, iPhone, WebOs Windows Phone 7 and BlackBerry.
Next concern is about Whrrl. It was recently acquired by Groupon and its service is not available now. But it is worth mentioning the special features it had, which made it unique among other similar applications. There users were enabled to create their own societies and join available societies based on their interest and places they like to visit. Check ins could be shared to the level they wish. Users could recommend places and post their points of view on others check ins and earn points. Whrrl was available on iPhone.
Yelp is popular location based social networking application which is available as a web app as well as a mobile app. Users can download it for free for any kind of smart phone which is running on iOS, Android, Blackberry, Windows7, and palm. It has a very large online community where by they have created a user reputation system. Therefore every visitor can see most popular, respected and prolific members. Business owners can also communicate with contributors who post reviews on their page via messages or public comments. The site has listings about the places like restaurants, clubs, museums, schools around USA and Canada. Yelp also has a "First to Review" reward system to create a competition among contributing members motivating to post reviews on places.
Koprol is another such application owned by yahoo. People can create an account on koprol and promote their businesses and carry on conversations with their customers. Users can download the mobile version also. App is available for almost all popular mobile platforms. Loopt and Bizzy are similar type of applications that have the same capabilities. There are some applications which diverse the above mentioned geo app series. Weddar is a community powered weather information system. It allows general public to post their comments on weather, based on their location. For example two people in the same city will post different feelings about the weather based on the actual condition. Users can easily get weather information without confusing scientific wordings.
Placing the people first is a general philosophy, the developers have followed all the way long in implementing geographic information systems. Emphasizing accessibility in the user interface and developing flexible system architecture are vital facts that affect to output a significant GIS Application.
