Satellite Imagery Processor

Processes raw satellite band data — files you already have on your machine — into RGB composites or spectral indices. Ported to the browser from a QGIS plugin built for people who work with raw satellite imagery. Every file stays local — nothing is uploaded anywhere; all decoding and band math run in this tab. Pansharpening, speckle filtering, and change-detection flood mapping from the source plugin aren't included in this pass.

Band data

Drop individual band GeoTIFFs (.tif/.tiff) — B02, B03, B04, B08, B05, B06, B07, B8A, B11, B12 — from one Sentinel-2 tile. Band codes are detected from each filename, so any naming that includes e.g. "B04" or "B8A" works, compact or full SAFE-style. JPEG2000 (.jp2) straight out of an unzipped .SAFE product isn't supported here — convert to GeoTIFF first (GDAL or QGIS can do this) if that's what you have.

Band combination / index

10 m (B02, B03, B04, B08) 20 m (includes SWIR bands)

Sensor

Landsat 8/9 (OLI/TIRS) Landsat 7 (ETM+) Landsat 4/5 (TM)

Auto-detected from the first file's USGS filename prefix (LC08/LC09, LE07, LT04/LT05) when it's recognized — pick manually otherwise.

Band data

Drop individual band GeoTIFFs (.tif/.tiff) named the usual USGS way — e.g. LC08_L1TP_..._B4.TIF — from one scene. The band number is read straight from the filename.

Band data

Drop the VV and VH polarization GeoTIFFs from one Sentinel-1 GRD product. Filenames containing "vv"/"vh" (any case, e.g. Copernicus's own ...-vv-...tiff) are matched automatically.

Output

Convert to dB (10·log10) before display

Applies to the single-band and RGB outputs — raw GRD amplitude/intensity has an extreme dynamic range that reads far better in dB. The RFDI and RVI4S1 indices always use linear values, per their published formulas, regardless of this setting.

Mission

SPOT 1/2/3 (Green, Red, NIR) SPOT 4/5 (+ SWIR) SPOT 6/7 (Blue, Green, Red, NIR)

Band count and order vary by mission — select which one your file matches.

Image file

SPOT multispectral products are usually one multi-band GeoTIFF with bands in a fixed order for the mission — drop that single file here.

Image file

Wyvern Dragonette products are one multi-band GeoTIFF — drop it here. The variant (Dragonette-001, 23 bands, 503-799nm, or Dragonette-002/003, 31 bands, 445-880nm) is detected automatically from the band count.

Band data

Drop individual band GeoTIFFs (.tif/.tiff) — B02 through B10 — from one EO-1 ALI scene, named the usual way (e.g. *_B5_L1GST.TIF). The band number is read straight from the filename. Panchromatic B01 isn't used by any composite here.
