GF-7 Satellite Imagery

Launched on November 3, 2019, the GF-7 satellite is a landmark achievement as China's first sub-meter, high-resolution stereo mapping satellite. Equipped with a dual-linear CCD camera and a precision laser altimeter, it is a primary source for 1:10,000 scale stereo mapping, delivering exceptionally accurate 3D data for the most demanding geospatial projects.

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.
