The new release of the Geographic Calculator introduces a number of tools aimed at the GIS Manager or Chief Geodesist to assist with developing geodetic and geospatial data quality controls in their organization.  Geographic Calculator 7.0 offers password-protected administrative lockdown controls that allow the manager to limit access to the GeoCalc geodetic data source.  Managers can use these tools to protect proprietary custom definitions or to guide users working in a particular part of the world by only exposing the appropriate projections, datums and other objects used in that area of the world.  Signatures on the data source can also alert users and administrators alike that the data source may have been inappropriately edited or corrupted.  New workspace settings allow the manager to construct conversion jobs, save them off and provide users with the appropriate template for a particular project.  Additionally, new datum shift envelopes defined by administrators and users can be assigned to particular datums based on geographic envelopes.  Users can still add custom definitions with these tools, but they will have to be approved by the administrator in order to be incorporated into the master geodetic datasource.  Use of any administrative or datasource lockdown is optional and at the discretion of the customer.

“Data can be corrupted in many different ways, unbeknownst to the GIS manager that is responsible for data quality and accuracy,” stated Patrick Cunningham, President of Blue Marble Geographics “Our tools provide a place to start defining methodologies and programs to control data quality.  These initiatives can really control risk, cost overruns and other unanticipated problems.”
