A questionInformation on the geographical distribution of population is commonly provided as an attribute of discrete polygonal aerial units, such as the Enumeration Districts used in many national censuses. However, several studies have attempted to produce population surface data sets from such data. Provide an explanation as to why it may be desirable to create population surface data sets from an initial discrete vector polygonal representation. In your discussion, you should consider the utility of both a discrete polygonal and surface representation of population in relation to GIS applications that may utilize such information.
