Excel®™ Addin SPATIAL FUNCTIONS

What are Spatial functions? Mathematical functions used to manipulate geographic locations. Examples include calculating the distance between two points and counting the number of locations within a radius.

Use these functions to bring spatial patterns and relationships to your spreadsheet. Gain insights into the spatial distribution of your data. "How close are my customers?" "How many people use this product within 5km of my store?"
