GeoTIFF Resampler

Resample a selected GeoTIFF band to explicit pixel dimensions with nearest-neighbour sampling in a local browser worker.

Nearest-neighbour sampling is appropriate for categorical data but may look blocky for imagery; this produces a preview, not a new GeoTIFF.

Choose a GeoTIFF up to 32 MB and 25 million pixels.

Understanding GeoTIFF Resampler

Cells, bands and derived values

Resample a selected GeoTIFF band to explicit pixel dimensions with nearest-neighbour sampling in a local browser worker.

GeoTIFF Resampler calculates from raster cells arranged in rows, columns and bands. Resolution, nodata values, band meaning and the raster CRS affect every derived value.

How to validate the analysis

Nearest-neighbour sampling is appropriate for categorical data but may look blocky for imagery; this produces a preview, not a new GeoTIFF.

Before interpreting GeoTIFF Resampler, check band selection, units, nodata handling and edge cells. Browser-generated results should be compared with known values for important work.
