Oceanodesy Coordinate Converter

The Oceanodesy iOS app enables you to convert geodetic coordinates (latitude and longitude) to grid coordinates (easting and northing) and vice versa.

The app also allows you to input a variety of coordinate formats, including decimal degrees, decimal minutes, and decimal seconds—and to enter grid coordinates as U.S. survey feet, international feet, or meters.
Oceanodesy supports a range of coordinate systems, including WGS84, NAD27, NAD83, ED50, and more.

Oceanodesy App Features

The app gives you the ability to store any converted points for future reference. This list can also be exported via email, iMessage, Twitter, or many other platforms via the iOS device’s native share functionality.
Each converted coordinated can be viewed in Google Maps. New coordinates can be entered and stored from the map as well.


Oceanodesy uses the proj.4 library, which is a well-established and supported geodetics library. This is the same library used by Oceaneering® C-Nav software applications.

The app is designed for use with all currently available iPhone, iPod, and iPad models, and runs on iOS 8.1 and higher.

If you have any questions, email app-support-oii@oceaneering.com. If you have any coordinate systems you would like to see added, please provide details and we will evaluate them for inclusion in our next release.

Company page Since our founding in the early 1960s, Oceaneering has expanded and grown globally to service several industries such as the offshore energy industry, defense, entertainment, material handling, aerospace, science, and renewable energy industries. In 1964, Mike Hughes and Johnny Johnson formed a Gulf of Mexico diving company called World Wide Divers. The company grew in response to increasing demand for their services and in 1969 merged with two other diving companies to form Oceaneering International, Inc. To solve the toughest challenges, we do things differently, creatively, and smarter. As your trusted partner, our unmatched experience and truly innovative portfolio of technologies and solutions give us the flexibility to adapt and evolve, regardless of market conditions. Our mission is to solve the unsolvable. We thrive by creating industry-changing technically creative solutions for the most complex operational challenges under water, on land, and in space. Our five core values establish a common culture and demonstrate what is most important for us as a company. Since the beginning, the company has transformed from a small regional diving company into a global provider of engineered products and services. Today, we develop products and services for use throughout the lifecycle of an offshore oilfield, from drilling to decommissioning. We operate the world's premier fleet of work class ROVs. Additionally, we are a leader in offshore oilfield maintenance services, umbilicals, subsea hardware, and tooling. We also serve the aerospace, defense, and theme park industries. Underpinning everything we do, safety is not only the foundation of our core values, but it is vital to our unmatched performance record and company culture. The industries we serve are as diverse as they are complex. Whether we are engineering deepwater umbilicals or developing robotics for aerospace applications, the safety and health of our employees, vendors, and customers is an integral part of our day-to-day business. If we are working, then our responsibility is to be working safely. Since our inception in 1964, we have placed a high value on employee safety—from diving services and subsea inspection to vessel-based installation operations. We have and will continue to evolve not only our health, safety, and environmental (HSE) processes, but those of the industries in which we work. Although we have been fatality-free since 1999, our HSE journey goes beyond statistics. As our portfolio of services has grown, we have continued to prioritize and advance our approach to HSE.
