Geographic Calculator 

ArcGIS Extension

Geographic Calculator v7 now has the ability to recognize when a user has ArcGIS installed on their desktop. The Calculator will install a special toolbar in ArcGIS, enabling users to access Blue Marble features directly in ESRI's ArcGIS Software. This exciting new capability for Calculator extends the power of ArcGIS as a geodetic definition and geospatial management interface. Calculator can also load reference files from other applications and output PRJ files which can be used and displayed in ArcGIS. 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.

ArcGIS Extension

The new Arc Extension allows users to work with the Geographic Calculator directly in ArcGIS. Some of the main features of this extension include:

• The ability to switch between geodetic definitions found in the Blue Marble GeoCalc XML data source and other geodetic definitions contained in existing ArcGIS
• Define and generate a custom PRJ using the Blue Marble coordinate system dialogues
• Load reference file info from 'application x', and output a PRJ file that can be used and displayed in ArcGIS
• Compare data conversion results from ArcGIS projects in Blue Marble.
• Convert a point layer in the Geographic Calculator and add it as layer in ArcGIS
• Use Blue Marble’s Administrative conversion rules and apply them for your ArcGIS or ArcMap users.
• ESRI Geodatabase conversions in the ArcGIS Extension for SDE, File Geodatabase, and Personal Geodatabase

Working with the Geographic Calculator directly in the Arc environment compliments the work that many Blue Marble users have been doing for years. Many GIS professionals double-check their coordinate conversion work in ESRI with Blue Marble’s Calculator to ensure data quality and consistency. However the latest new enhancements to the Calculator introduce new ways of extending the geodetic power of the ArcGIS environment. The new Administrative Tools in the Geographic Calculator allow users to define appropriate datum selection and thus datum shift by geographic envelopes. This will ensure that the GIS Administrator has control over conversion definition for project work in the Arc environment.
