# Analysis Tools

Aurora GIS provides a comprehensive suite of spatial analysis tools for vector and raster data.

## Overview

Analysis tools are organized into categories:

- **Proximity Analysis**: Buffer, nearest neighbor, distance calculations
- **Overlay Operations**: Intersect, union, erase, join operations
- **Spatial Analysis**: Hot spots, outliers, KDE, clustering
- **Raster Analysis**: Zonal statistics, raster operations
- **Feature Analysis**: Summarization and aggregation

## Vector Analysis Tools

```{toctree}
:maxdepth: 2

hotspot

```

## Raster Analysis Tools

```{toctree}
:maxdepth: 2

zonal-stats
raster-histogram
raster-summary
raster-profile
raster-conversion
raster-comparison
```

## Running Analysis

Analysis tools can be run via:

1. **Web Interface**: Use the analysis panels in the map viewer
2. **API**: Make POST requests to analysis endpoints
3. **Batch Tools**: Use the batch analysis interface

## Background Processing

Most analysis operations run as background jobs:

1. Analysis request creates a job in the queue
2. Worker processes the job asynchronously
3. Results are stored in a new dataset
4. User is notified when complete

## Output Formats

Analysis results can be stored as:

- **Static Table**: Permanent table with results
- **View**: Database view that updates with source data
- **Materialized View**: Materialized view requiring refresh
