What you can do with Göktürk-1

Detail at 50cm GSD

At 50cm GSD, vehicles are countable, and building outlines, road furniture and single trees stay distinct. The panchromatic band carries that geometry, and the 2m 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 2m GSD multispectral sampling, not the 50cm GSD panchromatic figure.

One satellite collecting

Collection rests on a single spacecraft, so opportunities arrive on its orbit rather than on demand. As stated by the supplier: 2 days with ±45° viewing angle above 30° latitude. 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: building heights, stockpile and pit surfaces, the shape of structures on the site you ordered.
