  2. Overview • Rationale of the geospatial tool • Case study • Objectives • Field organization • Use of mobile telephones • WebGIS application NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  3. Rationale • The main objective of a census operation is to ensure as much as possible full coverage • In most of traditional censuses the period of enumeration varies from 1 to 15 days • Need to establish monitoring tools for data collection to ensure high levels of coverage • Monitoring responsibility is traditionally assigned to field supervisors, but no control from the NSO during enumeration • Need to develop a real time monitoring tool accessible centrally from the NSO • Need to develop procedures for data checking in the post-enumeration phase NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  4. A case study: AlbaniaObjectives • To develop a Web Service Infrastructure for the 2011 population and housing census in Albania • To monitor the progress of data collection during the enumeration period • To support census field staff for orientation in the field • To ensure almost real time monitoring of data collection activities in remote by the NSO HQ • To report and facilitate public acceptance and participation to the census process NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  5. A case study: AlbaniaField organization of the 2011 census • 1 Enumerator responsible for 1 EA • 1 Controller responsible for monitoring and supervise 5 Enumerators • 1 Supervisor responsible for monitoring and supervise 6-7 controllers • Controller area: area assigned to 1 Controller • Supervisor area: area assigned to 1 Supervisor • 11 713 EAs • About 2 300 Controller areas • About 350 Supervisor areas NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  6. A case study: AlbaniaUse of mobile telephones • Enumerators, Controllers, Supervisors were provided with a sim card associated to their personal IDs • Field staff could communicate free of charge during the enumeration period • Each day Enumerators had to report via sms to a toll-free telephone number: no. of dwellings, households, individuals enumerated • The mobile operator was transferring every day to the NSO HQ the data received the previous day by sms • This data was uploaded on the WebGIS application developed for the monitoring of census coverage • The census staff at the NSO HQ and supervisors were accessing to the application in remote via web NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  7. A case study: AlbaniaWebGIS application • Published in the web as a map service • Accessible with a password NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  8. A case study: AlbaniaWebGIS application (cont.) • Available data • Name of the territorial unit queried • Percentage of the census units covered for the selected unit • Expected number of dwellings based on the pre-listing • Number of dwelling visited until the query date • Number of households interviewed until the query date • -Number of persons interviewed until the query date • Data accessible at levels of supervisor areas - controller areas - EAs, or by administrative units and grids NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  9. A case study: AlbaniaWebGIS application (cont.) • Progress of data collection by EA, in relation to the expected number of persons in that EA NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  10. A case study: AlbaniaWebGIS application (cont.) • Progress of data collection by Controller areas assigned to the same supervisor NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015

  11. A case study: AlbaniaWebGIS application (cont.) • Query based on administrative units NSD-AITRS Regional Workshop on the Integration of Statistical and Geospatial Information, Amman, 16-20 February, 2015
