Working with ArcGIS Network Analyst

Overview

Description
Built around the new network dataset, ArcGIS Network Analyst software incorporates an advanced connectivity model that more accurately represents real-world multimodal networks. This course teaches how to create network datasets and migrate existing data, such as shapefiles and coverages, into a network dataset. Participants work with network datasets to solve different types of network problems such as finding the most efficient travel route, finding the closest facility, and defining service areas based on travel time. The course also teaches how to calculate origin-destination matrices for network locations.

Who Should Attend
GIS analysts, managers, dispatchers, planners, and researchers who want to perform GIS-based routing and transportation network analysis. Those working in the transportation, logistics, public safety, local government, and business industries will find the seminar of particular interest.

Goals
After completion of this course you will be able to:
• Understand the fundamental concepts of the ArcGIS network dataset.
• Differentiate between network datasets and geometric networks.
• Create network datasets.
• Define network dataset properties such as network elements, connectivity groups, and network attributes.
• Migrate existing network data sources to ArcGIS network datasets.
• Generate and use turn movements within network datasets.
• Solve routing, closest facility, service area, and origin-destination problems.
• Perform network analysis using tools and models.
