Session 10 –
Use of geospatial tools during
census enumeration
By

CBS SUDAN
INTRODUCTION



The application of geospatial technologies( Gps /Gis/
Rs hand-held digital devices) in the collection of
georeferenced data for population census-mapping
improve the management quality and decrese time
and cost of all operations of census.
Verification of EA maps to know households location
will be the main issue for full coverage
.
Four topics discussed here:The role of technologies
to construct enumeration area (EA) level database
/how to integrate four technologies to verify EA
maps /theUse of four tools during census
enumeration/challenges of its with census mapping
operations dissimination example last census and
propoused coming census

TOPIC NO1: THE ROLE OF FOUR TECHNOLOGIES USED
IN (EA) LEVEL DATABASE
role of four technologies used in (EA) level
database are
 Gps link of central village names establish
ment and household location starting and
ending EA traking boundaries
 Rs f or identification of unconstrected
building plan and verify full delination of EA
 hand-held digital devices and verify progress
of the field work define each work of each
enumerater also all datatabase result in cspro
and excel of EA maps
 Gis all above dissimination
TOPIC NO2: INTEGRATING FIELDWORK USING GPS AND
REMOTELY-SENSED DATA HAND-HELD DIGITAL DEVICES TO
VERIFY
 GPS
EA MAPS
Integrating fieldwork and verify EA
maps can construct by tracking Ea
boudary and show all establishement to
describe boundary and lead to more
acceptin for enumerater to check his Ea
boundary
 remotely-sensed data Integrating
fieldwork and verify EA maps building
shape and check areas not included
 hand-held digital devices and verify
EA maps data concern EA for each EA
seprate in exel sheet by geocodes
