GeoTIFF Min/Max Stretch

Improve GeoTIFF contrast with measured min/max, custom value limits, or sampled 2nd-to-98th percentile stretching without sending raster values to a server.

Percentiles are calculated from a bounded deterministic sample. Custom limits affect display only and never modify the source file.

Understanding GeoTIFF Min/Max Stretch

Pixels, bands and spatial metadata

Improve GeoTIFF contrast with measured min/max, custom value limits, or sampled 2nd-to-98th percentile stretching without sending raster values to a server.

GeoTIFF Min/Max Stretch reads a grid of raster cells together with metadata describing bands, extent, resolution, CRS and nodata. Display colours may be a visual stretch rather than literal source values.

How to inspect the raster

Percentiles are calculated from a bounded deterministic sample. Custom limits affect display only and never modify the source file.

With GeoTIFF Min/Max Stretch, confirm the identified band, pixel location, nodata state and coordinate reference before relying on a displayed or reported value. Missing metadata limits what can be inferred spatially.
