Features and Benefits

  • Complementary Data: SJ-9A provides high-resolution visual data, while SJ-9B offers thermal data, allowing for a more comprehensive analysis of an area.
  • High-Resolution Optical: SJ-9A's 2.5m panchromatic resolution is excellent for detailed base mapping, infrastructure analysis, and land use classification.
  • Thermal Detection: SJ-9B's long-wave infrared sensor is ideal for detecting heat patterns, monitoring temperature changes, and identifying thermal anomalies.
  • Multispectral Analysis: SJ-9A's four multispectral bands enable standard vegetation analysis (NDVI), water body delineation, and environmental monitoring.

Applications

SJ-9A (Optical) Applications:
  • Urban Planning & Base Mapping
  • Land Use & Land Cover Classification
  • Agriculture & Forestry Monitoring
  • Post-Disaster Visual Assessment
SJ-9B (Infrared) Applications:
  • Thermal Anomaly Detection (Fires, Volcanoes)
  • Industrial Heat Monitoring
  • Water Temperature Analysis
  • Defense & Security Thermal Surveillance

Satellite Imagery Advisor

Brief questions. Practical guidance. Get an indicative estimate instantly, and we only proceed to a formal quote once the basics are clear.

Advisor mode: this form will recommend the lowest resolution and type that fits your objective so you do not overpay.
Step 1 — Area & Location
1 / 4
Start simple: Upload a KML/KMZ/ZIP if you have it. If not, a bounding box or center plus dimensions works fine. We will calculate area for you where possible.
Upload AOI file (KML / KMZ / ZIP) — recommended
Preferred: a single polygon AOI. We compute the area automatically.
Enter corner coordinates (bounding box)
Use min/max latitude and longitude.
Enter center coordinate + width & height
Good for quick feasibility when exact boundaries are not available.
Describe location (city / region / site name)
We will follow up to confirm an AOI boundary if needed.
Advisor note: If speed is the priority, we usually check archive first. If you need a specific date window or fresh capture, choose new tasking.
Archive imagery
Previously captured imagery, typically faster delivery.
New capture (tasking)
Satellite is tasked for your AOI; weather and availability can affect capture date.
Not sure, advise me
We will recommend the most feasible option based on area, timing, and objective.
Minimum order guidance
Archive imagery: typically 15 to 25 km²
New capture: typically 50 to 100 km²
Feasibility depends on satellite, location, and timing.
Pick a date window. We will advise what is realistic for your area and cloud conditions.
Resolution guidance: Higher resolution increases detail and cost. We will recommend the lowest resolution that meets your objective.
