Today, geo-coordinates are used by a wide range of sectors and industries, including but not limited to aviation, maritime, agriculture, surveying, mapping, transportation, and telecommunications. They are also extensively used by individuals for activities such as navigation, location-based services, and outdoor recreational activities.
This article will cover what constitutes geo-coordinate data, its history, and transmission.
What is Geo-Coordinate Data?
Geo-coordinates, short for geographic coordinates, pinpoint a specific location on the Earth’s surface. They consist of latitude and longitude measurements and are essential for accurately identifying and specifying a location.
Every place on the earth’s surface can be uniquely marked by an intersection of Latitude and Longitude as shown below:
This ability to give a unique marking in the format of [latitude: longitude] is what makes geo-coordinates necessary in creating addresses.
How to Access Geo-coordinates?
To access geo-coordinates, you can use a GNSS-enabled device such as a smartphone or a dedicated GNSS device. Many smartphones also offer the ability to access geo-coordinates through their built-in GNSS and mapping applications.
Additionally, there are websites and software applications that provide tools for accessing geo-coordinates based on addresses or landmarks. Another way to access geo-coordinates is through geographic information systems (GIS) software, which allows users to input specific locations and retrieve corresponding geo-coordinates.
Overall, accessing geo-coordinates can be achieved through a variety of tools and methods, depending on the specific requirements and use case.
How Smart Phones Get Geo-coordinates
All smartphones have a Global Navigation Satellite System(GNSS) receiver attached to the motherboard. When you enable location, the receiver receives signals from the satellite-based navigation systems.
These satellites transmit signals that the receiver uses to find its own position based on the time it takes for the signals to reach the receiver. By comparing the time it takes for signals from different satellites to reach the receiver, the device can accurately determine its location on Earth in terms of latitude and longitude.

Role of Geo-Coordinates in Addresses
The role of geo-coordinates in addresses is crucial for accurately pinpointing and locating a specific address on the Earth’s surface. This is especially useful for mapping and navigation purposes, as well as for various location-based services such as delivery logistics, emergency services, and geographic information systems. By incorporating geo-coordinates into addresses, it becomes easier to share and interpret location information, leading to improved efficiency.
