Substantial advances have been made in the last years towards the detection and quantification of methane emissions from space- very high spatial resolution data from the WorldView-3 satellite can fill an important observational gap in the remote sensing of methane point emissions.
WorldView-3 is the first multi-payload, super-spectral, high-resolution commercial satellite sensor operating at an altitude of 617 km. WorldView-3 is capable of collecting up to 680,000 square km per day.
The Quality Assurance Framework for Earth Observation (QA4EO) states "that all EO data and derived products have associated with them a documented and fully traceable quality indicator (QI)". In remote sensing, provision of uncertainty information is a fundamental aspect of indicating data quality: an uncertainty associated with a measurement is needed to allow proper interpretation and further application of data, both in scientific and decision-making contexts.
