PRE-CENSUS MAPPING HOUSE LISTING

• To ensure complete coverage, the whole country
  was
• segregated into 6800 Enumeration Area maps
• exhaustively.
• Every Structure ( Temporary, Permanent, caves,
• shelters) have been coordinated with GPS
  (Global
• Positioning System) system.
• Parallel to the Mapping of Enumeration Areas,
  the house
• listing for every structure had been
  accomplished.

GIS for Population Housing Census 2005

• Data capture from the Topographical maps.
• Production of Enumeration Area maps both in
  digital and
• analogue forms.
• Delineation of Enumeration Area boundary through
  given
• administrative units and sub-units (Dzongkhag,
  Geog
• chiwog boundary).
• To decide the data dissemination administrative
  level.
• To decide the data analysis administrative level
  for future
• planners and policy makers.
• To set the base reference for future population
  and Housing
• census of Bhutan.

Objectives of GIS for PHCB-2005

• Generation of Geo-database for PHCB 2005
• To facilitate and widen the scope in the use of
  
• census data especially at the smaller area
  level.
• To produce the socio-economic maps using the
• census data at different categories.
• Dissemination of Census data at different level
  for
• different user organizations.
• Finally to create the bench mark data for the
  next
• population and housing census of Bhutan.

REQUIREMENTS

• The GIS software used for Population and
• housing Census 2005 from ESRI products
• like Arcview or Arc info or Arcgis of latest
  version.
• The office of the census commissioner had
  procured
• the one GIS softwares as it entails huge
  budget.
• The market rate for one license Arcgis is
  about Nu.
• 1.9 million.

WORK METHODOLOGY

• Digitizing of the Topographical maps in
  different layers of the available Topographical
  sheets in 150000
• Mosaicing of the same layers to include in the
  administrative
• boundary
• Cropping of the mosaiced layers as per the
  existing Dzongkhag
• boundary.
• Cropping of digital layers to the geog level in
  Dzongkhag.
• Cropping of Digital layers to the Chiwog level
  in Geogs.
• Creation of Shp.file from GPS coordinates.
• Preparation of Enumeration Area Maps digitally.
• Merge EA maps into chiwog maps for further
  processing.
• Accordingly merge for geog and Dzongkhag for
  processing.

Database Design

• At what level the information dissemination had
  to be done
• The information in database to be aggregated
• To calculate the statistical factors
• How to link the processed data with the map
  layers.
• The SPSS or the CSPRO softwares compatibility
  should be
• explored for data linking and matching.
• The data dissemination strategy should be
  planned well.

15
