Introduced by Syed Waqas Zamir et al. in iSAID: A Large-scale Dataset for Instance Segmentation in Aerial Images archive 2025-07-28

iSAID contains 655,451 object instances for 15 categories across 2,806 high-resolution images. The images of iSAID is the same as the DOTA-v1.0 dataset, which are manily collected from the Google Earth, some are taken by satellite JL-1, the others are taken by satellite GF-2 of the China Centre for Resources Satellite Data and Application.

13 shown of 13 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 81. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
