GIS Mapping
Overview
The GIS Mapping module provides a Google Maps-based visualization of property
locations, zone boundaries, and MMDA geographic areas. It displays properties
on an interactive map with zone overlays, allowing administrators to view
property density, verify location data, and manage geographic boundaries.
