A tessellation is a pattern of tiles that covers a plane without any gaps or overlaps. In GIS, tessellations can be used to represent spatial data as a series of regular, uniformly sized cells. Each cell in the tessellation represents a particular location on the earth’s surface, and the attributes of that location can be stored in the cell.

Introduction ‘GIS’ comprising the three words ‘Geographic’ or ‘Geographical” Information’ and ‘System’ simply means that it is the system of analysing the information (data) collected from various fields about the earth (geo). When we use the word ‘geographical’ the concepts of ‘space’ and ‘time’ immediately comes to our mind. Thus the limits of the ‘GIS’
