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.
