Agenda GIS Census Building for Results for GIS the GIS census 2

Building the GIS SPATIAL ADDRESS DATABASES 3

BUILDING THE GIS GIS in Polish official statistics as of 2009 4

BUILDING THE GIS Spatial address databases Statistical address points • address points for dwelling locations (only) Statistical division borders • Statistical regions • Census areas 5

BUILDING THE GIS Reference materials Primary : • Ortophotomap, • Cadastral Data, • Administrative division borders, Secondary : • LPIS (Land Parcel Identification System), • Road and street network (commercial), • Geographical Names, • Topographic Data Base. 6

BUILDING THE GIS Work schedule (nationwide) January 2010 – continuously May 2010 since July 2010 • reference • address point material acquisition • reference • address point collection material database processing update January 2009 – January 2010 – December 2009 June 2010 7

BUILDING THE GIS Results 210 GIS operators in 63 regional offices 6 months time (January – June 2010) 5,7 milion statistical address points acquired GIS built from scratch in a very short time 8

Census for GIS CENSUS UPDATE OF ADDRESS POINTS 9

CENSUS UPDATE OF ADDRESS POINTS Update in municipalities January 2011 – 3 weeks • municipality authorities obliged to verify address point location • internet map service with on-line editing • results imported automatically to spatial address databases 10

CENSUS UPDATE OF ADDRESS POINTS Visual survey by enumerators • mobile application • every address point verified • results imported to spatial address databases 11

CENSUS UPDATE OF ADDRESS POINTS Results The only set of address points in Poland that: • is complete, • has been verified in the field, Created and maintained within official statistics 12

GIS for census CENSUS MANAGEMENT WITH USE OF GIS 13

GIS IN CENSUSES Census applications Dispatcher Dispatcher application supervision Mobile Enumerator application 14

GIS IN CENSUSES Dispatcher application Enumerator supervision • task assigment • address points • interviews • trail monitoring • support Census completeness monitoring 15

GIS IN CENSUSES Dispatcher application – table view 16

GIS IN CENSUSES Dispatcher application – map view 17

GIS IN CENSUSES Mobile application Smartphone • mobile app • VPN network Map module • GPS • orthoimagery • cadastral data • tasks Communication module • phone (to dispatcher only) • messaging • alarm procedure Census module • tasks • questionnaire 18
