Overview
Built around the network dataset, ArcGIS Network Analyst software incorporates an advanced connectivity model to accurately represent 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 in order to model and analyze transportation networks. Students 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.
