Use of geospatial tools during census enumeration Session 10 – Use of geospatial tools during census enumeration By Abdel Gadir Mohamed Ahmed elsadig 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 EA maps GPS 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

Topic No3: Use of geospatial tools during census enumeration quality assurance, Gis lead to all residential and administrive areas known from map in the office geocode identification gps tracking accual boundry map in handed devise curser and work progress otematic edit inside devise EA map production,digital map needed to be download in devise befor enumeration to guidenumerater annd to know work progress and coverage database maintenance listingform database to distribute the work cspro device data can analize data and can be change to excel data for gis link, use of digital maps for census logistics tracking ـ work progres and lead to prevent data duplication unenumerated and mix monitoring progress of census operations vehcel distrubution ـ save time and cost no paper sending online , map use by enumerators during the census,digital map in devise can identify building ـ restrict EA boundary ـcoverage updating and correction of EA maps during enumeration, any update during enumeration done by Gps [n device and added in paper or specific digital way .) 

Topic No4: Institutional, organizational and technological challenges with census mapping operations Institutional challenges trained staff ـ spatial data centre cost cont. of electricity ـbulk need of devices Organizational challenges online ـ 0regjnal programs ـ Raw data security technological challenges small areas spaial analysit ـ geocode agreggation ـ devise gps acuracy ـ cspro link to map ـ Gps in English language ـ Saving track 20 save the machine full
