## Editorial
Jilin Imager is a high-resolution visible imager and movie camera associated with the Jilin-1 mission record.[^wmo-jilin-imager][^wmo-jilin-1] This configuration uses a 500-800 nm visible channel, full-colour mode, 4.7 m sampling and a 9.6 km swath, with area-array gaze and linear-array pushbroom imaging modes.[^wmo-jilin-imager] It has demonstrated optical time-series change detection and optical transient detection uses on Jilin-1 data.[^wmo-jilin-imager] Later Jilin-1 commercial optical products span multiple satellite series and finer product classes; those figures are not the specifications of this imager configuration.[^cgstl-geo-presentation]
