Abstract : Today ease access of computers and modernization leads to increased Internet users day by day. Social media are a medium to communicate information to the public while Geographical Information System (GIS) is a technique, which focuses on communication of geographical information. The fact is this GIS communicates geographical information stored in digital form. This paper focuses on one of application of geographic data of popular social media platform Twitter users by generating heat map with Quantum Geographic Information System (QGIS) tool, supported by GIS technology. Which can also use to calculate the user density within a particular region to get useful information. The same method can be apply for other social media platforms as Facebook, LinkdIn, Pinterest, Instagram etc. to inferred meaningful results.
