0.7m GF7 Satellite - 2021 Geological Satellite Imagery of Yulin, Shaanxi
Applications of the GF7 Satellite in the Geology and Mining Industry
The 0.7 m GF7 (Gaofen-7) satellite of China is mainly used for high-precision topographic mapping. Its applications in the geology and mining industry include:
| Satellite | Gaofen-7 (GF7) of China — sub-meter optical stereo mapping satellite |
|---|---|
| Resolution | 0.7 m panchromatic; stereo mapping for high-precision 3D terrain |
| Case area | Yulin, Shaanxi Province, China — geological imagery captured in 2021 |
| Dataset | 38 scenes (Fig. 1–Fig. 38) shown below |
1. Geological mapping
Captures surface details for high-precision geological maps; quickly identifies geological bodies, terrain changes and fault structures.
2. Mineral exploration
With multispectral data, identifies mineral spectral features for anomaly delineation; monitors pits, mine scale and mining status.
3. Post-disaster assessment
Rapid high-resolution imagery after landslides and debris flows for loss assessment and restoration planning.
4. Open-pit monitoring
Dynamically monitors mining extent and waste piles; compares long-term imagery to assess ecological impact and remediation.
5. Fault-zone monitoring
Identifies surface faults, especially in mountains and canyons, supporting tectonic activity analysis.
6. DEM generation
Stereo mapping generates high-resolution DEM for mine planning and slope-stability evaluation.
7. Remote-area prospecting
Locates surface anomalies in remote and uninhabited areas to guide follow-up field surveys.
8. 3D modeling
Combines with ground surveys for 3D mine modeling and virtual geological analysis with higher efficiency.
