Geographic Calculator 2016 Overview

A powerful windows solution with particular strength in survey, seismic and energy exploration, The Geographic Calculator is available in 32 or 64 bit versions. This highly accurate transformation software includes tools such as Canadian DLS (Dominion Land Survey) Land Grid tools, Seismic Survey Conversion tools, Area of Use tools for guiding users, and much more. The Geographic Calculator supports a wide range of file formats with support from the largest geodetic parameter database available anywhere. When transformations have to be correct, consistent and certifiable, GIS professionals around the world choose the Geographic Calculator.

The Geographic Calculator is THE Global Coordinate Transformation tool for any coordinate or geomatic challenge.

​

Since 1993, The Geographic Calculator has been the coordinate conversion tool of choice for GIS and survey professionals around the world. The Geographic Calculator quickly grew in popularity over that first decade and has maintained its reputation as the best coordinate conversion solution on the market. The 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 the Geographic Calculator. Blue Marble incorporated all of the functionality of the desktop including the Geographic Transformer, Translator and Spatial Connect products into the Geographic Calculator. This did away with the confusing versioning and introduced an easier-to-follow annual naming convention with one or two service pack updates between releases.

Today the tool provides a single platform for highly accurate coordinate transformation of virtually any type of geospatial data and includes features such as:

  • Support for Windows 10 machines and improved installation process

  • XML based coordinate object library

  • Project Manager for data processing, jobs, and workflow management

  • Start Page offering a user-friendly introduction to the key features and functions

  • Administrative Tools to customize the datasource and restrict editing access

  • Unmatched Geoid or Vertical Datum support, including VDatum support

  • Powerful Survey Seismic format support

  • Raster Geo-referencing, Reprojecting, and Vector File Translation Tools

  • The ability to customize and send all or part of your GeoCalc datasource to Global Mapper

  • Esri Extension and powerful CAD support

The all-in-one interface of the 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.

The 2016 version introduces a completely redesigned interface to streamline workflow and to provide easy access to the important components of the application. 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. Reorganized menus and updated toolbar buttons have been implemented to facilitate efficient data processing. The Point Database Conversion job has been 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 2016 Service Pack 1 release introduces support for reading coordinate systems from Petrel™ coordinate databases as well as offering access to the new GeoCalc Geodetic Registry, which provides streamlined database updates throughout the year.

Point Database - Conversion

The Point Database Conversion job allows for conversion and transformation of tabular numeric coordinates. Coordinate data must be uniformly organized into columns with all coordinates in a given column being relative to the same coordinate reference system. Multiple conversions can be performed across several sets of columns. There is no limit to the length of database that can be processed via the Point Database Conversion job. This job can be used as a template for a batch process.

Supported Input Types:

  • Manually entered numeric coordinates

  • Microsoft Excel (.xls, .xlsx)

  • dBase (.dbf)

  • Microsoft Access (.mdb)

  • ASCII Text files (.csv, .tsv, ...)

  • ODBC databases

 
 Convert point databases, including your own text file formats

​

Point Database - Forward & Inverse

The Point Database Forward or Inverse job calculates paths between positions in tabular numeric coordinates. Coordinate data must be uniformly organized into columns with all coordinates in a given column being relative to the same coordinate reference system and both the left and right coordinate systems must share a common geodetic base. There is no limit to the length of database that can be run via the Point Database Conversion job. This job can be used as a template for a batch process.

  • Forward: Calculates the endpoint of a traverse from an input coordinate and distance/azimuth away along the path of a geodesic, rhumb line, or grid line

  • Inverse: Calculates geodesic, rhumb line, or grid Distance and Azimuth between two input coordinates

Supported Input Types:

  • Manually entered numeric coordinates

  • Microsoft Excel (.xls, .xlsx)

  • dBase (.dbf)

  • Microsoft Access (.mdb)

  • ASCII Text files (.csv, .tsv, ...)

  • ODBC databases

 

Point Database - Scale & Translate

The Point Database Scale and Translate job allows for conversion and transformation of tabular numeric coordinates. Coordinates can be shifted, rotated, and stretched, by manually entering in the parameters of the desired transformation. These are commonly used for old survey data where control data may not be available for a higher accuracy transformation. Coordinate data must be uniformly organized into columns with all coordinates in a given column being relative to the same coordinate reference system. There is no limit to the length of database that can be run via the Point Database Conversion job.

Supported Input Types:

  • Manually entered numeric coordinates

  • Microsoft Excel (.xls, .xlsx)

  • dBase (.dbf)

  • Microsoft Access (.mdb)

  • ASCII Text files (.csv, .tsv, ...)

  • ODBC databases

 

Point Database - Best Fit

The Point Database - Best Fit job derives a polynomial transformation relating two coordinate systems together, based on geodetically-based control points. One coordinate system will be an arbitrarily defined local ground coordinate system, the second will be a geodetic control. Two sets of coordinates are required, one for each system. This is commonly used to transform mine grids, airport ground grids, or any other local survey or engineering plan coordinate system to a geodetic or projected system.

Supported Input Types:

  • Manually entered numeric coordinates

  • Microsoft Excel (.xls, .xlsx)

  • dBase (.dbf)

  • Microsoft Access (.mdb)

  • ASCII Text files (.csv, .tsv, ...)

  • ODBC databases

Point Database - Derive Datum Shift

The Derive Datum Shift job allows you to calculate a 3 or 7 parameter coordinate transformation between two geodetic coordinate systems. Two sets of coordinates are required, one for each system. The input coordinates can be Projected or Geodetic, the only requirement is that they are both geodetically based.

Supported Input Types:

  • Manually entered numeric coordinates

  • Microsoft Excel (.xls, .xlsx)

  • dBase (.dbf)

  • Microsoft Access (.mdb)

  • ASCII Text files (.csv, .tsv, ...)
