Bare Soil & Bare Land Satellite Images – Urban Vacant-Land Views from China's 0.8 m GF-2 Satellite

Published: April 12, 2023  |  Source: Original article  |  Satellite: Gaofen-2 (GF-2)
This is a use case of China's first 0.8 m-resolution satellite — Gaofen-2 (GF-2) for urban vacant-land monitoring, including bare-soil satellite images and bare-land satellite images. With 0.8 m resolution, bare soil or bare land larger than 10 m × 10 m can be clearly observed. Imagery is updated about once a month at an affordable price of about 100 yuan per km²; monitoring one city each time costs 20,000–30,000 yuan on average. To purchase bare-soil / bare-land satellite imagery, please contact the staff of Beijing OMap company via Contact Us, and click Online Search to view more satellite project cases.

✅ Why GF-2 for bare-land monitoring?

  • 0.8 m detail clearly separates bare soil, construction sites and vegetated land.
  • Wide swath + monthly revisit, ideal for city-wide vacant-land inspection.
  • Domestic data (China) with fast delivery and low cost.

📌 Typical workflow

  • 1. Order monthly GF-2 coverage over the city.
  • 2. Extract patches > 10 m × 10 m (bare soil / bare land).
  • 3. Compare periods & dispatch field inspection.
