Understanding GeoTIFF Slope and Aspect

Cells, bands and derived values

Calculate slope in degrees and summarize aspect from a GeoTIFF elevation band entirely inside a browser worker.

GeoTIFF Slope and Aspect 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

Results depend on correct elevation units, affine resolution, and CRS; geographic degrees are not automatically converted to metres.

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