High-Resolution Video – Nighttime – Mono Jilin-1 Imagery Added to Image Hunter!

Apollo Mapping is excited to now offer high-resolution Jilin-1 imagery from a constellation of satellites owned and operated by CG Satellite. This new partnership unlocks a constellation of thirteen satellites in four different series (i.e. Optical, Video, GF and KF) launched between 2015 and 2020. With a robust archive accessible through Image Hunter, the Jilin-1 product suite includes nighttime, video and mono imagery!

With the ability to collect both during the day (a 75-cm KF series image from Los Angeles is featured here) and at night (a 92-cm nighttime image from London), the Jilin-1 constellation never leaves you in the dark. (Images Courtesy: CG Satellite)

Jilin-1 offers an impressive variety of resolutions from 72-cenitmeter (cm) to 1.06-meter (m). It’s also the only constellation boasting an array of unique capabilities, like 120-second color video collected at 92-cm resolution; and 92-cm color nighttime imagery. Five satellites in the Jilin-1 Video series also collect a 3.68-meter red edge band for vegetation mapping; while one satellite in the KF series collects data with a massive 136-kilometer (km) wide footprint. With so many satellites in orbit, Jilin-1 revisits the same location up to six times a day, resulting in a robust archive filled with regional coverage images.

Check out some of the interesting specifications that sets the Jilin-1 constellation apart from its competitors:
