Raster Histogram

Analyze pixel value distributions in raster datasets.

Overview

Raster histogram analysis generates histograms showing the distribution of pixel values in raster datasets.

Inputs

Raster Dataset: Raster dataset to analyze
Band (optional): Band to analyze (default: first band)
Bins (optional): Number of histogram bins

Outputs

Histogram data containing:

Value ranges for each bin
Pixel counts for each bin
Statistics (min, max, mean, median)

Example

{
  "raster_dataset_id": 125,
  "band": 1,
  "bins": 256
}

Use Cases

Data distribution analysis
Quality assessment
Value range identification
Visualization preparation

Notes

NoData values excluded
Results depend on raster data type
Bins affect histogram resolution
Large rasters may take time to process
