This Blue Marble Desktop download file contains both Geographic Calculator and Geographic Transformer. If you have already downloaded the latest Blue Marble Desktop or the latest Desktop Edition of Geographic Transformer, you've already downloaded this file and simply need to install it to run Geographic Calculator 7.4.

This download file can be used for Single User, USB Dongle and Network license types.

Please note that if you are upgrading to this version of the software, you will need to remove any previous versions of the Geographic Calculator before installing version 7.4.

If you are evaluating the Geographic Calculator, you may use the License Wizard to obtain a 7 day temporary license. Please explore the user interface and features of the product. You will be able to perform interactive coordinate transformations, file conversions and limited point database conversions to assist in your evaluation. You can purchase single user, USB dongle, or network licenses for Version 7.4.

IMPORTANT NOTICE:
If you are installing this version as an upgrade to previous version, please follow these directions:

Note: Calculator 7.0 workspaces are not compatible with 7.4 workspaces, however, latter version workspaces should be ok. To be safe you should make notes on your workspaces prior to installing 7.4.

1.) If you have created custom Coordinate Systems in a version of Transformer previous to 6.0 or Calculator previous to 7.0, please move your 'geocalc.dat' file (the parameter database) to a new location to avoid any custom coordinate systems being overwritten..
2.) If you had Calculator 7.0 installed and have created custom Coordinate Systems there, please backup your 'custom.xml' found in 'C:\Documents and Settings\All Users\Application Data\Blue Marble Geographics\Geographic Calculator\7, 0, 0, 0\DataSource'.
3.) It is not necessary to uninstall the Calculator 7.x, but it is recommended. If your version is older then 7.0 please uninstall it now.
4.) Install Blue Marble Desktop. This will insure we install our latest version of the geocalc.xml file.
5.) Once you have Blue Marble Desktop running, you can import your old geocalc.dat file by selecting 'Import GeoCalc DAT' from the Options menu.
6.) To use a previous custom.xml, it will need to be copied to the following directory for Windows XP:
C:\Documents and Settings\All Users\Application Data\Blue Marble Geographics\Blue Marble Desktop\DataSource\
or for Windows Vista:
C:\ProgramData\Blue Marble Geographics\Blue Marble Desktop\Datasource
7.) Please see the Release Notes for more details of this process.

This step-by-step guide allows you to evaluate the functionality available in the Blue Marble Desktop, including the Geographic Calculator. Sample images and data files are provided for use with this Getting Started Guide, however you may also use your own files. You can obtain an authorization code after you purchase the product that fully enables all of the powerful features of the product. You can purchase single user, floating (portable), dongle, or network licenses for the Geographic Calculator.
