AutoCAD Map is software from AutoDesk Corporation. In general, the software was developed to support data processing and analysis in Geographic Information Systems (GIS). Nearest neighbor analysis is one of the analyzes used to explain the distribution pattern of location points by using calculations that consider distance, number of location points, and area area. The final result in the form of an index calculation varies from 0 – 2.15. The distribution of this shopping center produces a Nearest Neighbor ratio or T of 0.927720 with an average distance (Expected Mean Distance) of 953.8998 Meters and a z-score of -0.769890.
