For over 25 years, Geographic Calculator has been universally recognized as the leading geodetic toolkit for accurate coordinate conversion and datum transformation.
Geographic Calculator is a powerful geodetic application with particular strength in survey, seismic, and energy exploration. In addition to single point, point database, and file conversion tools, this highly accurate transformation software includes many specialized tools such as Canadian DLS (Dominion Land Survey) Land Grid tools, Seismic Survey Conversion tools, Area of Use tools for guiding users to the most appropriate transformation settings for a specific location, Horizontal Time-Dependent Positioning (HTDP), Geoid Creation tools, and much more. Geographic Calculator supports a wide range of file formats and is built on the foundation of the largest geodetic parameter database available anywhere. When transformations have to be correct, consistent and certifiable, GIS professionals around the world choose Geographic Calculator.
Geographic Calculator provides a single platform for highly accurate coordinate transformation of virtually any type of geospatial data and includes features such as:
The 2016 version introduced a completely redesigned interface to streamline workflow and to provide easy access to the important components of the application.
The all-in-one interface of Geographic Calculator enables users to complete a number of geodetic and geospatial transformation functions on various types of data in the same interface with unmatched accuracy and accountability. The enterprise collaboration tools, such as workspaces and network folders, enable consistency and repeatability of highly accurate data translation across your organization.
For new users, a consolidated Start Page provides clear and concise explanations for each type of calculation and serves as a launching pad for easy access to the various jobs. Intuitive menus and toolbar buttons facilitate efficient data processing. The Point Database Conversion job is split into five logical components: Conversion; Forward/Inverse Calculation; Scale and Translate; Best Fit; and Derive Datum Shift. This simplified approach provides a unique and intuitive interface for each type of calculation. The highlight of the 2017 release is the introduction of a new Seismic Survey QC Job for checking the quality of preplot and poststack seismic lines between UKOOA and SEG-Y files.
Recent releases have seen the introduction of a new Seismic Survey QC Job for checking the quality of preplot and poststack seismic lines between UKOOA and SEG-Y files, an updated, and more user-friendly interface, a universal copy and paste function, a new angular unit conversion tool, and support for NADCON 5.0.

Since 1993, Geographic Calculator has been the coordinate conversion tool of choice for GIS and survey professionals around the world. The software quickly grew in popularity over that first decade and has maintained its reputation as the best coordinate conversion solution on the market. Geographic Calculator has come a long way since then with many improvements over the years. In 2004, the underlying GeoCalc library was re-written and in 2007 a new version was released as the Blue Marble Desktop.
2013 saw a rebranding of the Blue Marble Desktop to Geographic Calculator. Blue Marble incorporated all of the functionality of the Desktop including the Geographic Transformer, Translator and Spatial Connect products into Geographic Calculator.
