 Efficient Method to Develop a New Layer, Intersecting Multiple Layers Track: Transportation Author(s): Madhav Pai, Neelita Mopati Transportation system analysis begins with dividing a metropolitan region into traffic analysis zones (TAZ). A TAZ layer is built from multiple layers representing same or different feature classes. This makes it difficult and time-consuming to construct, especially for a person with limited GIS knowledge. Furthermore, socioeconomic data must be aggregated by TAZ; this requires building a correspondence between the TAZ layer and other layers. This presentation will demonstrate how a person with limited GIS knowledge can efficiently develop a clean TAZ layer with existing tools. Examples will illustrate problems encountered and precautions to minimize them. This technique can be applied whenever one wants to create a new layer from multiple layers representing same or different feature classes.
