Tell me how the geospatial model is established

The basic idea of ??modeling: determine the regional scope - establish a conceptual model - logical model - physical model - spatial database

First, select the region in the real world, determine the regional scope, and It abstracts and simplifies expression and establishes a conceptual model.

Secondly, data encoding is performed on the abstract concept set of geographical things and phenomena in the conceptual model to express and establish spatial logical structural relationships.

Finally, organize the spatial data in the logical structure, establish a spatial database and store it inside the computer.
