For one to three teams together there is one supervisor and a drive
The role of the supervisor was to coordinator field data collection activities, including management of the field teams, supplies and equipment, coordinate with local authorities concerning the survey plan and make arrangements for any boundaries conflict (communicate with responsible ministry). Additionally, the field supervisor assigned the work to the interviewers, spot checked work, make sure all data are sent to central server daily or when there is stable internet. Communicate with central sever officers to make clarification about any doubt in his/her team
Each field team comprised of 2 field mappers and a driver. For one to three teams together there is one supervisor and a driver. A total of 306 mappers, 165 supervisors and 6 GIS experts and IT (station in the server) were used to collect and editing data. Data collection took place from January 14, 2020 until May 30, 2022. Interviewing took place everyday throughout the fieldwork period, although interviewing teams were permitted to take one day off for editing and correction before sending data to server.
Data processing
The data editing, since the programme for data collectioon connect direct to server, so data editing was done in field with team after checking by office team if there is overlapping or shifting of boundary, or naming of the place or coding.
Data appraisal
The spatial accuracy of the dataset is estimated to be within 3 meters, ensuring precise location information for each ward boundary.
