Explanation / Answer

10) Soil type is not an example of a continuos dataset and falls under discrete data set as the change between soil type of two regions form a sharp boundary. Surfaces are continuous data, such as elevation, rainfall, pollution concentration, and water tables. This data can be represented as a continuous surface, generally without sharp or abrupt changes.

11) Census data is not an example of remote sensing data product.A census is a procedure of systematically acquiring and recording information about the members of a given population. It is not done by using any remote sensing techniques rather involves teams going each household and taking into account of family members.

12) True, according to Codd's rule for relational database design, it is most often ideal and most efficient for a single database field to contain multiple data values.

13)Buffering is the process of creating one or more zones around selected features, within a pre-specified distance ( from these features. The resulting buffer is an area object or series of area objects (typically polygons) that may be automatically merged (dissolved) where they overlap. Hence Buffering is geoprocessing operation in GIS.
