GIS (Geographic Information System) and Google Maps are both tools that allow users to visualize, analyze, and interpret geographic data, but they serve different purposes and offer different capabilities.

1. Purpose and Functionality:
- GIS, such as ArcGIS, is a comprehensive system designed for capturing, storing, checking, integrating, manipulating, analyzing, and displaying data related to positions on Earth's surface. It is used for a wide range of applications including urban planning, environmental science, resource management, and more. GIS allows for complex analysis and modeling, spatial data management, and integration with other data systems.
- Google Maps, on the other hand, is a web-based service that provides detailed information about geographical regions and sites around the world. It is primarily designed for navigation and locational purposes, allowing users to find directions, explore places, and view satellite imagery, street maps, 360° panoramic views of streets (Street View), real-time traffic conditions, and route planning for traveling by foot, car, bicycle, or public transportation.

2. User Base:
- GIS software is typically used by professionals and analysts who require advanced tools for spatial analysis, such as geographers, urban planners, environmental scientists, and GIS analysts.
- Google Maps is aimed at the general public and is widely used by millions of people for everyday navigation and exploration.

3. Data Analysis and Processing:
- GIS offers advanced spatial analysis tools, including overlay analysis, buffer analysis, network analysis, and spatial statistics. Users can create and edit maps with multiple layers of data, perform complex calculations, and simulate scenarios.
- Google Maps provides basic data visualization and does not offer the same level of analysis or data manipulation. It is not designed for in-depth spatial analysis or editing geographic data.

4. Customization and Extensibility:
- GIS software like ArcGIS can be customized extensively. Users can write scripts and build models to automate tasks, create custom tools, and integrate with other software. It also supports a wide range of data formats.
- Google Maps has limited customization options, primarily through its API, which allows developers to embed Google Maps on webpages and customize some aspects of its appearance and functionality.

5. Data Ownership and Privacy:
- With GIS, organizations often use their own data, which they can control and keep private if necessary. They can also use public data and integrate it with their proprietary data.
- Google Maps uses data collected and owned by Google. While users can contribute to the platform through services like Google Map Maker, they do not own the data and have limited control over it.

6. Cost:
- GIS software, especially professional-grade applications like ArcGIS, often requires purchasing licenses or subscriptions, which can be costly.
- Google Maps is free for personal use with some limitations on the number of requests per day. For commercial use, Google offers paid plans through the Google Maps Platform.

In summary, while both GIS and Google Maps deal with geographic information, GIS offers a much more robust and sophisticated set of tools for spatial data analysis and manipulation, catering to professional and analytical needs. Google Maps, conversely, provides an easy-to-use interface for navigation and basic location-based services for the general public.
