1. GIS for Population and Housing Census of Bhutan 2005By
THINLEY JYAMTSHO WANGDI
Geo-Informatics Division
National Statistics Bureau

2. 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.

3. 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.

4. 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.

5. GIS PROCESSING BUILD DATA DESIGN THE DATABASE
INPUT SPATIAL DATA (DIGITIZER)
EDIT AND CREATE TOPOLOGY
INPUT ATTRIBUTE DATA
MANAGE AND MANIPULATE THE DATA
ANALYZE THE DATA
PRESENT THE RESULT OF ANALYSIS

6. 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.

7. WORK METHODOLOGY
Digitizing of the Topographical maps in different layers of the available Topographical sheets in 1:50000
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.

14. 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.
