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
