Background of the action The first report: http://europa.eu.int/comm/eurostat/Public/ datashop/print-catalogue/EN?catalogue =Eurostat&collection=12-Working% 20papers%20and%20studies [Theme: General Statistics] (Issue Date: 18/09/2002) PDF -file 154 pages with pictures 200 pages October 23, 2002 The Tandem Consortium, M T-L

The Tandem Consortium, M T-L ... Need to increase comparability of spatial statistics - demand for comparable building blocks/territorial division for European system of small area statistics -for visualising data more effectively -for combining and comparing data on different spatial units -for combining or comparing data on different spatial scales -for making better statistical/spatial analysis of data (to test spatial patterns and trends) - October 23, 2002 The Tandem Consortium, M T-L

The Tandem Consortium, M T-L … Two parallel approaches: regular tessellation, irregular tessellation Iterative method for RD: 1. Study user needs (Case studies) 2. Formulate (Re-formulate) a vision (The desirable) 3. Design (Re-Design) of a prototype 4. Test and evaluation (Searching the feasible) 5. Recommendations (for next iterations) October 23, 2002 The Tandem Consortium, M T-L

Tandem II Objectives of the action 1) to formulate a strategy for development of SSAS 2) to build a reference system of data as a model 3) to build comparable and harmonised data sets 4) to develop sharable methods - for inner and outer delineation of urban areas 5) to discuss some specific problems 6) to focus on case studies for development of urban statistics and spatial analysis of urban issues October 23, 2002 The Tandem Consortium, M T-L
