1. GEOG3025 Exploratory analysis of neighbourhood data

2. GEOG3025 Census and administrative data Lecture overview *Change to Census Registration System* Objectives of lecture Introductory questions Exploratory (spatial) data analysis Neighbourhood Statistics CASWEB/CommonGIS

3. GEOG3025 NB: Updated registration system (8 Mar 04)

4. GEOG3025 Special conditions…

5. GEOG3025 Objectives To review the principles of exploratory data analysis To examine tools for exploratory spatial analysis of neighbourhood data –(Not using the Neighbourhood Statistics Service) –(Not Using GIS software) –Using CASWEB/CommonGIS

6. GEOG3025 Introductory questions… What is exploratory spatial data analysis? How might it apply to neighbourhood data? Which tools should I use?

7. GEOG3025 NeSS Interactive Mapping

8. GEOG3025 NeSS thematic mapping Owner occupation: wards

9. GEOG3025 NeSS thematic mapping Conventional choropleth (shaded area) mapping One variable at a time Little control over class breaks No interactivity No linked plots

10. GEOG3025 Exploratory spatial data analysis Spatial pattern detection Hypothesis formulation Some aspects of spatial model fitting Specifically: –What makes neighbourhoods different? –Why might these patterns be present? –Can we explain/predict the observed relationships?

11. GEOG3025 Login to Casweb

12. GEOG3025 Select data as usual…

13. GEOG3025 Select ‘Visualisation’ option

14. GEOG3025 Why not use GIS? Data management philosophy rather than data exploration Sophisticated spatial data manipulation Few statistical and analytical tools Cartographic rather than statistical approach to mapping Less interactivity Rarely offering dynamically linked plots
