Geospatial tools in Abu Dhabi Census 2011 1. Design and production of enumeration areas • In 2010, SCAD undertook a frame update process (establishments, buildings and persons). • This frame, combined with new buildings data from municipalities, formed basis for designing Census 2011 enumeration areas. • Each enumerator assigned to a single work area (WA). Each WA could be divided into max 4 sub-working areas (SWAs). • Over 4, 200 WA maps and 11, 300 SWA maps created. • Used ESRI Arc. GIS for map design and quality control. 6

Geospatial tools in Abu Dhabi Census 2011 GIS – Defining the Census working areas • Each enumerator assigned to a single work area (WA) and up to 4 subworking areas (SWAs). • Over 3, 500 WAs and 12, 000 SWAs created. • Production of Census enumeration areas outsourced to GIS company Map. Tel. • Quality assurance of every map conducted by SCAD over 4 week period. • Using ESRI Arc. GIS. 7

Pads and Galaxy Tabs as primary collection instrument. • Each contained: interactive questionnaires (Arabic/English), GPS, mapping system, and reference material.

Geospatial tools in Abu Dhabi Census 2011 • The mapping system displayed the allocated work area for each unique enumerator and presented the buildings visited and those remaining both in the i. Pad & Galaxy Tab and in Census back office. 10

Geospatial tools in Abu Dhabi Census 2011 • The mapping system also allowed tracking of each enumerator in the Census back office. 11

Dissemination: web service application 3. Census dissemination - on-line thematic maps • A recent UN review of population and housing censuses 1 indicated that “only 17 countries (16 per cent) use interactive online databases” for census dissemination. • SCAD is making a dedicated effort to provide innovative, informative and free web-based tools to the public. • As such SCAD, is developing three on-line statistical information tools for accessing the rich source of census data. 1 Report of the United States of America on the 2010 World Programme on Population and Housing Censuses. 13

Dissemination: web service application • Census release date - May 2012. • On-line tools: o Census Thematic maps o Census Community Tables o Census Table Builder • The thematic mapping application will provide unique visual analysis of the rich Census data. • ‘Clusters’ or ‘hot spots’ are easily identified. 14

Dissemination: web service application on-line thematic maps Functions: • o Select from range of census variables. o Select geographic level (e. g. sector). o Select range types Run ------------------o All standard mapping functions: zoom, pan, transparency, export, print, change mapping features (e. g. colours of ranges), etc. o Dual language (English/Arabic) Development: o Data - SAS/Oracle o Base map - ADSIC (GIS Cloud facility) o Interface - Arc. GIS API Flex (Flash) 15
