Find Hot Spots (Grids)
Overview
The Find Hot Spots tool generates a grid of equal-sized cells based on your defined extents. You can create grid cells based on the current extent, study area extent, or extent of a feature in another layer. You can append demographic data to a grid cell to provide a normalized view of the data, identifying hot spots and areas of interest. The hot spot grid areas appear with prominent red coloring by default.
Input Prerequisites
This is a defined extent.
Example Output
This example shows a typical Grid analysis output created in Business Analyst:
- A default thematic layer is added to the map symbolized from the variable you choose.
- The attribute table contains unique cell identifiers and aggregated data for each selected variable for every cell.
- By default, the variable is divided into five classes using natural breaks and added to the table of contents.
