What is a grid model?


Critical Points of IntegrationMaximo ArcGIS ODMS

Unversioned hierarchical model of logical locations and physical assets

Versioned geospatial representation of grid elements, master of grid connectivity

Versioned grid model of grid connectivity and electrical characteristics
