Why Generalize? • Data is collected and maintained in high detail 1: 12, 500

Why Generalize? • Data is collected and maintained in high detail • When drawn at a smaller scale: - Too detailed - Unclear 1: 12, 500 1: 50, 000

Why Generalize? • Data is collected and maintained in high detail • When drawn at a smaller scale: • - Too detailed - Unclear Generalization automates the creation of scalespecific data - Removes the need of multiple scale production lines - More consistency than manual generalization - Saves time and money 1: 12, 500 1: 50, 000

Generalization Workflow

General Workflow

General Workflow Divide Data

General Workflow Divide Data Generalization

Feature Generalization • Features assessed individually without regard to symbology or spatial relationships

Contextual Generalization • Features from multiple layers assessed simultaneously - Maintain pattern, density, and spatial relationships

Production Mapping Tools

Generalization Techniques • Simplify • Smooth • Eliminate • Amalgamate • Exaggerate • Collapse • Typify • Thin

Cartography Generalization Tools • Simplification • Smoothing • Amalgamation • Roads • Buildings

Production Mapping Generalization Tools • Exaggeration • Maintaining Topological Relationships • Hydrography • Vegetation

Exaggeration Tools • Increasing the size or separation between features so that they are more legible or for more emphasis Increase Line Length Extend Polygon Sides Increase Polygon Area

Maintaining Topological Relationships Coincidence Assess multiple features from multiple layers simultaneously to maintain topological relationships Connectivity Delete Polygon and Extend Line Generalize Shared Features Fill Gaps

Building Generalization Models

Assess the data • Small features (less than 10 square meters) should be converted to points

Find the tool and add to a model

Contextual Generalization • When a large number of buildings are close together create a built-up area

Find the tool and add to a model

Run the models

Python tools to run outside of Arc. Map
