# GIS Spatial Analyzer Skill

## Purpose

The GIS Spatial Analyzer Skill performs spatial analysis including watershed delineation, floodplain mapping, buffer analysis, and land use classification.

## Capabilities

- Watershed delineation
- Floodplain mapping
- Buffer analysis
- Slope analysis
- Land use classification
- Right-of-way analysis
- Viewshed analysis
- Proximity analysis

## Usage Guidelines

### When to Use
- Analyzing site constraints
- Delineating watersheds
- Mapping flood zones
- Evaluating land use

### Prerequisites
- GIS data available
- DEM for terrain analysis
- Boundary data defined
- Analysis criteria established

### Best Practices
- Use appropriate resolution
- Verify data sources
- Document methodology
- Validate results

## Process Integration

This skill integrates with:
- Flood Analysis and Mitigation
- Stormwater Management Design
- Highway Geometric Design
