Blue Marble’s geospatial data manipulation and conversion solutions are 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.

This Webinar will demonstrate the Geographic Calculator best-fit functionality, which allows users to relate their local coordinate systems to any standard geodetic or projected coordinate systems.  With a set of control points, you can create a local fitted system. This fitted system is then permanently added to your custom datasource, and can be used for conversions between your local system and WGS84 or any other of the hundreds of coordinate systems that are part of Blue Marble’s extensive datasource. Users can choose the mathematical model for their best-fit analysis, from affine up to fifth order polynomial. With dockable windows, enhanced workflow tools and the ability to export to other users, Blue Marble will save you time and money on every project. The Geographic Calculator allows users to work with raw survey data to conduct a best-fit transformation to take grid data to geodetic easily and correctly, also making use of the georeference tool. Learn why GIS analysts and surveyors that need to bridge the gap between highly accurate survey data and user-friendly GIS data turn to Blue Marble.
