Internet Role in Remote Sensing and Geo Informatics System

Abstract

Remote sensing and geo informatics system (GIS) are difficult to find the source and accessibility of various applications by end users such as students, scholars, scientists and professionals. The overall objective of the learning is to compare as well as analyze the various applications of remote sensing by end users particularly in Tamilnadu. In this technical survey, total 114 people have participated, among them males and females are about 61.2% and 38.8% respectively, most of the people are at age group of 17-27. It is observed that students are the highest of about 36.9%, professional are 31.1%, research scholars are 26.2% and finally professors by 5.8% took the survey. Remote sensing and GIS applications are mostly used in the fields of survey/planning (51.5%), disaster management (49.5%), climate change (43.7%) and followed by agriculture/forestry (45.6 %.). The most generally used software’s are identified as ArcGIS, ENVI, ERDAS and QGIS in remote sensing and GIS users. It is revealed that, 37% of people have moderate usage of cloud mapping and 21% of people have never used of cloud mapping. From ANOVA results, there is no significant difference in remote sensing and GIS role among location, educational qualification, type of sector, type of data and web GIS. There is a significant difference in remote sensing and GIS role among the age, gender, occupation, experience and software groups. The survey leads to the conclusion that the above groups have an effect on internet role in remote sensing and GIS. It is concluded that Internet plays a major role in geographic information systems and remote sensing by 95.1% of people and only 4.9
