RDBMS is widely used in GDI for storing and managing geospatial data due to its structured data model, support for spatial data types, and ability to handle large volumes of data.

The vector data model is commonly used in GDI to represent geospatial features and their relationships. It stores data as points, lines, and polygons, allowing for precise representation of geographic features.

GIS software is commonly used in GDI for capturing and editing geospatial data. It provides tools for creating, modifying, and managing geospatial data, allowing users to input and update geographic information.

GIS software is commonly used in GDI for visualizing and analyzing geospatial data. It provides tools for creating maps, charts, and other visualizations, allowing users to explore and analyze geographic information.

Web mapping technology is commonly used in GDI for sharing and disseminating geospatial data. It allows users to access and interact with geospatial data through web browsers, enabling easy sharing and visualization of geographic information.

Metadata is commonly used in GDI for managing and coordinating geospatial data. It provides information about the data, such as its source, accuracy, and usage, enabling users to understand and utilize the data effectively.

Data validation is commonly used in GDI to ensure the accuracy and quality of geospatial data. It involves checking the data for errors, inconsistencies, and outliers, and correcting or removing them to improve the reliability of the data.

Data integration is commonly used in GDI to integrate and combine different types of geospatial data from various sources. It involves bringing together data from different formats, scales, and projections, and creating a unified dataset for analysis and visualization.

Spatial analysis is commonly used in GDI to analyze and extract insights from geospatial data. It involves applying statistical, mathematical, and geospatial techniques to identify patterns, relationships, and trends in the data, enabling users to gain insights and make informed decisions.

Web Mapping Services (WMS) is commonly used in GDI for creating and managing geospatial web services. It allows users to access and display geospatial data over the internet, enabling easy sharing and visualization of geographic information.

Data standards are commonly used in GDI to ensure the interoperability and seamless exchange of geospatial data. They define common data formats, structures, and protocols, enabling different systems and applications to communicate and share data effectively.

Geospatial ontology is commonly used in GDI for representing and reasoning about geospatial knowledge. It provides a formal framework for defining and organizing geospatial concepts, relationships, and properties, enabling computers to understand and reason about geographic information.

GPS (Global Positioning System) is commonly used in GDI for capturing and representing real-time geospatial data. It provides accurate location information by receiving signals from satellites, enabling users to collect and update geospatial data in real-time.

Cloud Computing is commonly used in GDI for storing and managing large volumes of geospatial data. It provides scalable and cost-effective storage solutions, allowing users to store and access geospatial data from anywhere, anytime.

3D GIS is commonly used in GDI for creating and managing 3D geospatial models. It provides tools and techniques for visualizing and analyzing geospatial data in three dimensions, enabling users to gain a more comprehensive understanding of geographic information.
