Blue Marble Geographics releases version 9.0 of the GeoCalc Software Development Kit

Hallowell, Maine – January 18, 2023 – Blue Marble Geographics (bluemarblegeo.com) is pleased to announce the immediate availability of version 9.0 of the GeoCalc® Software Development Kit (SDK). The GeoCalc SDK allows developers to embed the advanced coordinate transformation toolkit behind Geographic Calculator into their own programs.

Providing the tools behind Blue Marble’s Geographic Calculator to developers, GeoCalc version 9.0  includes support for updates in EPSG and Horizontal Time Dependent Positioning toolkit, NADCON 5 and NTv2 transformation grids, and new live filter search dialogs. 

The GeoCalc SDK remains an industry standard tool for developers through continual updates and improvements. Evolving as the GIS and geodesy industry does, the new release of GeoCalc includes an updated datasource to EPSG database version 10.078. Additionally, velocity information provided by the relevant survey authorities is now available for Horizontal Time Dependent Positioning version 3.4.2-based transforms here in the United States, as well as the Canadian time-based transformations.

In the new dialogs, the search bar has been expanded to allow users to search using partial terms, and use a live filter search. With this update, users can search without knowing the full name or even what category or regional grouping to find it.

The update also improves support for the new toolkit by the National Geodetic Survey (NGS) known as NADCON 5. In GeoCalc, more detailed information about transformations and accuracy is now easily accessible on an individual point basis, an impressive new capability important in high-accuracy mapping applications as we move towards future surveying technologies and coordinate systems.

“Following on the heels of the Geographic Calculator 2023 release, GeoCalc SDK 9.0 brings important updates to Horizontal Time Dependent Positioning and NADCON5 tools to our users,” stated Sam Knight, Director of Product Management, “We are particularly excited to be unveiling the GeoCalc SDK search dialog updates to our SDK users as well, representing the largest change to the dialogs in recent history.”

The GeoCalc SDK is a fully object-oriented class library designed for GIS professionals and software developers. Blue Marble Geographics offers the underlying coordinate transformation capability of the Geographic Calculator within GeoCalc.
