4. Spatial Analysis of Statistics -Answering Where & How! • Data Users are often not only interested in answering the- • “How much” question, but • “How much is Where” question • Spatial (Geographic) Analysis of Statistics- • Transforms Data into Information, and • Presents results to the users in a concise and easy to understand manner For Example- Population Distribution representation through Maps

8. Spatial Analysis Techniques- Processes & Methods • Requires Geo-referencing & Coding of Data Units- • Spatial Analysis of Census Data requires proper Geo-referencing and Coding of Data Units for collection and representation of Data. • This is to be done at the time of Census Operations and a Census Geography Database is to be created, e.g., Qatar Census Geography

14. Thematic Mapping-Spatial & Temporal Common Choropleths- Color Maps Advanced Dasymetric Mapping- using geographic layers such as Land use Volumetric Mapping- Estimating and Representing Statistics at small Data Units level for which Census data is not made available- e.g., for Buildings falling with in a Census Block Queries- Where & How and sometime answering Why! Transformation- Buffering- Point, Line & Polygon Spatial Analysis Techniques Processes & Methods- Some Prevalent Forms useful with Population data

15. Contd.. Spatial Interpolation- method designed to fill in values that lie between observations (Samples). The type of analysis include- Kriging- estimate the values of unsampled sites- Thiessen polygons- assumes that the values of the unsampled data are equivalent to those of the sampled points. Centre of Population- used to display the center of population using the weighted average of x and y coordinates of populated points Cluster analysis- regards the distribution of points in space irrespective of their actual locations to determine whether patterns are random, clustered, or dispersed Hot Spots- are where high values are surrounded by high values, or cold spots, where low values are surrounded by low values.
