Clip GeoTIFF Preview

Mask a GeoTIFF preview to a supplied GeoJSON Polygon or MultiPolygon using raster pixel-centre containment in the browser.

The polygon coordinates must use the raster CRS. Pixels are included by their centre and the source GeoTIFF is never rewritten.

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

Understanding Clip GeoTIFF Preview

Cells, bands and derived values

Mask a GeoTIFF preview to a supplied GeoJSON Polygon or MultiPolygon using raster pixel-centre containment in the browser.

Clip GeoTIFF Preview 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

The polygon coordinates must use the raster CRS. Pixels are included by their centre and the source GeoTIFF is never rewritten.

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