Part 1 - Introduction
(Download .pptx|5MB)

Part 1 is the ideal place to begin for those who are new to using the Density Processing tool. It demonstrates how to load the ArcMap file used with the Density Processing Tool and how to set up ArcMap for use with the Density Processing Tool.

Part 2 - Getting Started
(Download .pptx|5MB)

Part 2 orients the user to the operation and functionality of the Density Processing tool. In this tutorial, the user will learn how to create customized density layers for specific NAICS codes and load them into ArcMap. In addition, how the Density Processing Tool creates density layers is explained.

Part 3 - Creating Density Layers
(Download .pptx|15MB)

Part 3 teaches the user how to create density layers for sets of counties or other regions using files included with the Density Processing Tool. It then provides a detailed explanation of how to optimize density layers for viewing.

Part 4 - Checking Your Data

Part 4 provides the user with methods of confirming that a density layer portrays density for its business type accurately. Potential problems with density layers are and their symptoms are introduced.

Part 5 - Correcting Density Layers
(Download .pptx|20MB)

Part 5 shows the user how to correct errors in density layers, or modify them to present the desired type of density faithfully. It also shows how to create density layers for sub-county areas.

Part 6 - Relating Density to Truck Traffic
(Download .pptx|24MB)

Part 6 of the introductory tutorials demonstrates how to use the Truck Visualization Layers (included with the Density Processing Tool folder) to examine the relationship between different types of density and truck volume on the surrounding roads.

Part 7 -Correcting the Input File

At times, there may be the need to add information to a density layer to account for businesses that are not represented in the layer. A user can add business information from surveys or external sources by editing a copy of the original NAICS shapefile and creating new density layers from that shapefile
