RADIOMETRIC QUALITY ASSESSMENT FOR MAXAR HD IMAGERY

Abstract. The requirement for very high-resolution satellite imagery by different applications has been increasing continuously. Several commercial and government-supported missions provide sub-meter spatial resolutions from optical sensors aboard Earth Observation (EO) satellites. MAXAR constellation acquires images with up to 30 cm Ground Sampling Distances (GSDs); the High-Definition (HD) image production technology developed doubles resolution using artificial intelligence methods. Although is one of most important quality metrics, several other factors indicated diverse radiometric geometric characteristics may circumscribe usability data in projects. As part mandatory activities European Space Agency (ESA), Earthnet Programme provides a framework integrating Third-Party Missions into overall EO strategy promotes international use data. Data Assessment Pilot (EDAP) project aims at assessing suitability TPMs, communication platform between mission providers ensure coherence systems. In this study, HD products was evaluated within EDAP General Image-Quality Equation (GIQE) visual inspections, comparative assessments orthophotos obtained an Unmanned Aerial Vehicle (UAV) original (non-HD) resolutions. results show that improvements are observable urban areas, where sharp edges present. However, blurring color noise patterns also occured images.
