Blue Marble’s Geographic Calculator Supports INSPIRE Parameters

The Irish Grid joins hundreds of unit, ellipsoid, datum transformation, and coordinate system definitions, including many from standard government, corporate, and EPSG/POSC databases, all available in the Geographic Calculator. Blue Marble’s coordinate conversion technology is used worldwide by thousands of GIS analysts at software companies, universities, oil and gas companies, civil engineering, surveying, technology, enterprise GIS groups, government, and military organizations.

The Geographic Calculator allows organizations and individuals to maintain and transform large datasets in many formats and local coordinate reference systems, guaranteeing the highest accuracy possible. The INSPIRE project seeks to solidify a spatial information infrastructure that delivers accurate, quality data in an easily shared format. The Calculator is the perfect tool for any INSPIRE-focused user or community. With support for over twenty GIS and CAD file formats, over five thousand pre-defined coordinate reference systems, and transformations, interoperability has never been so easy. Also, the Geographic Calculator is highly customizable. With just a few quick clicks, users can create a new coordinate reference system, transformation, or simple file reader. All of these customizations can then be shared with any other user. If data is saved in a custom text format, the Geographic Calculator allows users to reformat the data without losing any header records. Users can transform, update, and process multiple datasets and output the results in the format needed.

The Geographic Calculator provides over twenty different datum transformation models, ranging from simple three parameter shifts, to various local grid formats, and even high order polynomial transformations. With our extensive geodetic database, you know that the coordinate transformation you are using is the right one for your data.

“The Geographic Calculator is widely used in Europe and known as a great component to surveying and map data manipulation and creation,” stated Blue Marble President Patrick Cunningham. “Many countries have unique datum issues and transformation challenges that can only be addressed through the use of an object oriented, open coordinate transformation library like that found in Blue Marble GIS data conversion solutions.”
