Dissolve By Attribute

You can use the Dissolve By Attribute functions on the Sales Potential Modeling wizard with the output from the original or advanced Huff model and dissolve the attribute probability field. For example, you can create primary, secondary, and tertiary trade areas based on the output probabilities of the original Huff model. The output from the Huff Model tools in Business Analyst creates a probability for each subgeography unit in the study area. For example, the output from the Huff models creates a probability of households in each block group for patronizing a new store location.

The Dissolve By Attribute option allows you to collapse the probability attributes in the block groups to create trade areas. For example, you can create three trade areas with the following:

• 70–100 percent
• 40–70 percent
• 10–40 percent

In this case, the layer created would contain the three polygon features based on the ranges above. You can use these trade areas to target potential clients in these areas to suit your business needs, such as marketing campaigns or sales territory generation.

Use Dissolve By Attribute when you want to aggregate and dissolve features based on a specified attribute or attributes. For example, you could take a layer containing sales data collected on a county-by-county basis and use the Dissolve By Attribute option to create a layer containing contiguous sales regions based on the name of the salesperson in each county.
