GIS-Remote sensing-QA

Accountabilities: Interpret high-resolution satellite and aerial imagery to identify, classify, and assess physical features and changes within the built environment. Compare imagery captured at different dates to identify spatial changes and document observations accurately and consistently. Validate interpreted features against reference datasets, identify discrepancies, and record uncertainty where applicable. Digitize, update, and maintain spatial features and associated attributes using QGIS and/or ArcGIS. Assess imagery suitability for analysis by considering spatial resolution, acquisition date, cloud cover, shadows, and other image-quality factors. Perform detailed geospatial QA/QC checks to verify the accuracy, completeness, consistency, and reliability of project deliverables. Prepare, validate, and manage datasets in formats such as SHP, KML/KMZ, GeoJSON, and GeoTIFF. Document analytical methods, observations, quality findings, and project outcomes in a clear and structured manner. Create maps and concise analytical summaries to communicate findings effectively to project stakeholders. Support project teams in resolving data discrepancies and maintaining consistent geospatial interpretation standards. Requirements: 4–5 years of professional experience in GIS, remote sensing, satellite imagery interpretation, or a closely related field. Hands-on experience working with high-resolution satellite and/or aerial imagery. Strong visual interpretation skills, including the ability to recognize built features, land disturbance, surface characteristics, and changes over time. Experience with multi-temporal imagery comparison, change detection, feature validation, and reference-data analysis. Proficiency with QGIS and/or ArcGIS for visualization, digitization, spatial analysis, and geospatial data management. Strong understanding of imagery quality factors, including resolution, acquisition timing, cloud cover, shadows, and their impact on interpretation confidence. Practical experience performing geospatial quality assurance and quality control. Familiarity with SHP, KML/KMZ, GeoJSON, GeoTIFF, and other commonly used GIS data formats. Strong attention to detail and the ability to identify subtle inconsistencies or spatial discrepancies. Good analytical, organizational, documentation, and communication skills. Ability to work independently while maintaining consistent quality standards and project timelines. Experience interpreting urban imagery or mapping the built environment is preferred. Familiarity with commercial high-resolution satellite imagery providers or imagery platforms is an advantage. Bachelor’s or Master’s degree in Geography, Geoinformatics, Remote Sensing, Civil Engineering, Urban Planning, or a related discipline. Benefits: Full-time consultant/freelancer opportunity based in India. Onsite or hybrid working arrangement, depending on project requirements. Opportunity to work extensively with high-resolution satellite and aerial imagery. Hands-on experience across GIS, remote sensing, geospatial analysis, and quality assurance. Opportunity to contribute to projects involving urban mapping, built-environment analysis, and change detection. Exposure to widely used GIS tools and industry-standard geospatial data formats. Collaborative environment with opportunities to support project teams and contribute to high-quality geospatial deliverables. Professional opportunity to further develop expertise in GIS, remote sensing, imagery analysis, and geospatial QA/QC.
