  In this era of twenty first century, Google Earth (GE) delivered tangible advantage to the users. The reliability of people searching the geographical location of the earth on GE service increases and to use its geospatial information for different mapping purposes due to its high spatial resolution of raster data and other ancillary information. The study aimed to generate three separate vector layers from three different time-series satellite data of GE on the same geographical location of the earth. Since the vector layers were superimposed in a particular frame, it was observed that layers were found to be not congruent, as the multi-temporal satellite imagery of GE were shifted from one another. In order to examine the shifted error and to rectify the geometric distortion of vector data, the mathematical formulas were used in the study. Initially, Hav.. View More»
