Jilin-1 GF03D
Part of the Jilin-1 constellation, the GF03D series satellites provide high-resolution Earth observation with both panchromatic and multispectral imaging capabilities.
Technical specifications
What you can do with Jilin-1 GF03D
Detail at 75cm GSD
At 75cm GSD, buildings, road networks, field boundaries and mature trees read clearly, while street-level objects do not. The panchromatic band carries that geometry, and the 3m GSD multispectral bands are pansharpened against it, so colour products hold the same detail.
Standard index bands
Blue, green, red and near-infrared cover the everyday products: true colour, colour infrared, and the indices built from red and near-infrared (NDVI) or green and near-infrared (NDWI). Those index rasters carry the 3m GSD multispectral sampling, not the 75cm GSD panchromatic figure.
7 satellites collecting
7 satellites fly this specification, so there are more chances of a usable pass inside a tasking window and a deeper archive to search before anything is tasked. As stated by the supplier: Up to 12 revisits per day. That is the cadence to plan against; a cloud-free result usually takes more than one opportunity.
Stereo for elevation
Stereo pairs are collectable, so elevation comes out of the imagery itself instead of a global model: landform, terrain and the massing of built-up areas across your site.
