# 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

```json
{
  "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
