Individual National Consultant to Develop a Digital Map of Enumeration Area Framework for Viet Nam's Household Surveys and MICS, Viet Nam

Overview

National consultant to support the National Statistics Office of Viet Nam in developing a digital enumeration area framework for household surveys and MICS, strengthening national capacity for its maintenance and future use.

Key Responsibilities

• Lead day-to-day liaison with NSO units to access, clarify and organise geospatial and statistical datasets.
• Document data custodians, versions, formats, coordinate systems, coverage, update dates, access constraints and known limitations.
• Work jointly with the international consultant to develop and maintain a structured geospatial database and file management system.
• Conduct and document checks for completeness, positional and attribute consistency, coding, duplication, missing values, geometry validity, topology and temporal compatibility.
• Clean, harmonise and prepare datasets through open-source workflows, executing and adapting R and/or Python scripts.
• Maintain the project database, open-format files, folder structure, data dictionary, processing log, parameter files and version records.
• Implement the pilot EA delineation workflow, execute scripts and parameter configurations, conduct contextual and operational checks, prepare maps and diagnostics, document exceptions and recommended modifications.
• Support the processing and integration of administrative boundaries, structure coordinates, road networks, waterways, building footprints, population datasets, and other relevant spatial layers.
• Assist in the application and testing of delineation procedures developed by the international consultant.
• Execute, test and document R and/or Python scripts.
• Contribute national knowledge to thresholds, administrative constraints, physical barriers, accessibility, urban/rural treatment, islands, fragmented territories and justified exceptions.
• Prepare maps, statistics and diagnostics, assess operational plausibility, and document method-specific errors, parameter sensitivity and areas requiring contextual review.
• Implement production workflow and maintain metadata, method and parameter records, quality flags, exception flags and urbanisation classifications.
• Execute automated quality-control routines developed jointly with the international consultant.
• Check boundaries, metadata and supporting layers for geometry errors, gaps, overlaps, slivers, non-contiguity, administrative violations, duplicate or missing identifiers, missing attributes and threshold deviations.
• Review automated results against national geographic knowledge, identify false positives and context-specific exceptions, and prepare method-comparison QA tables and maps.
• Coordinate validation sessions, maintain comments, decision and exception logs, revise assigned datasets and parameters, verify reproducibility, and support final acceptance checks.
• Jointly develop a comprehensive competency-based five-day training programme for NSO staff and adapt examples and exercises to Viet Nam’s institutional, geographic and data context.
• Prepare and test training datasets, open-source environments, R and/or Python scripts, practical exercises, expected outputs and troubleshooting guidance.
• Co-deliver technical sessions and provide hands-on support.
• Support assessments, record questions and capacity gaps, identify potential technical focal points or internal trainers, and organise editable materials for continued NSO use.
• Maintain detailed records of national data sources, preparation steps, parameters, processing runs, validation comments, exceptions, decisions and revisions.
• Contribute substantive national-context sections to the comparative methodology report and prepare maps, comparison outputs, QA summaries, decision logs and technical annexes.
• Review and test README files, data dictionaries, execution instructions, environment specifications and troubleshooting guidance for usability by NSO staff.
• Document national arrangements for ownership, approval, updating, versioning, code custody, maintenance and training, and support final open-source handover and reproducibility verification.

Required Experience

• At least 10 years of professional experience in GIS, geospatial analysis, cartography, or spatial data management.
• Experience working with government geospatial datasets and administrative boundary data in Viet Nam.
• Experience using GIS software for spatial analysis, database management, and map production.
• Experience supporting census, survey, statistical, land administration, or planning activities is desirable.
• Experience working with national statistical offices, government agencies, development partners, or research institutions is an asset.
• Experience supporting GIS training, technical workshops, or capacity-building activities is desirable.

Qualifications

Master's degree in Geography, GIS, Geoinformatics, Geomatics, Cartography, Statistics, Demography, Spatial Data Science, Computer Science, or related fields.
