A geographic data model, geospatial geographical measurements, or simply data from modules in the context of geographic information systems (GIS), is a mathematical and digital structure for …

data model [data architecture] The rules or specifications by which data is defined and organized within a system, such as an application or a database.

These models, known as GIS data models (or geospatial data models), are a set of constructs and abstractions for describing and representing geographic entities in a digital system.

Once you find a relevant data model, you can download a geodatabase template from the site that you can use to jump-start your design. You can build a test geodatabase, load some data into it, then test …

Representing the “real world” in a data model has been a challenge for GIS since their inception in the 1960s. A GIS data model enables a computer to represent real geographical elements as graphical …

In order to visualize natural phenomena, one must first determine how to best represent geographic space. Data models are a set of rules and/or constructs used to describe and represent aspects of …

In addition to the two main data models, there are other data models that may be described as variants, hybrids, or special forms by some GIS users, and as different families of data models by others.

Each data model has strengths and weaknesses in terms of functionality and representation. As you get more experience with GIS, you will be able to determine which data type to use for a particular …

This page discusses the two main GIS data models: raster and vector. Raster is fast and easily interpretable but may lack detail, while vector provides precise spatial representation and lower …

Data models are a set of rules and/or constructs used to describe and represent aspects of the real world in a computer. Two primary data models are available to complete this task: raster data models …
