1. A ground system, comprising:
an artificial satellite configured to:
capture a satellite image;
execute a subsample extraction process on the captured satellite image;
generate first partial data based on the execution of the subsample extraction process, wherein
the generated first partial data corresponds to a first subsampled image;
generate additional data based on the execution of the subsample extraction process, wherein
the generated additional data corresponds to a second subsampled image,
a first pixel of the first subsampled image is sampled by the subsample extraction process,
a second pixel of the second subsampled image is sampled by the subsample extraction process, and
the second pixel is different from the first pixel;
a ground station; and
an image processing unit configured to:
analyze the generated first partial data; and
request transmission of the generated additional data from the artificial satellite to the ground station, based on a analysis result of the analysis of the generated first partial data, wherein
the generated additional data corresponds to the generated first partial data.
