Blue Marble introduces automatic projection recovery for map files

With the release of Blue Marble Desktop 2.0 a few weeks ago Blue Marble Geographics ( introduced never before seen functionality for automatic projection recovery for both raster and vector data.  Whether it is coordinate, vector, or raster data the Blue Marble Desktop allows users to address data conversion challenges in the same application interface with powerful conversion and transformation tools. 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.

The Projection Recovery Tool automates the process of determining the original projection information associated with mapping data when that information is lost and no longer associated with the data.  Through a sort of reverse interpolation via the GeoCalc coordinate system engine, the application determines the most likely projected coordinate system used to reference vector or raster data.  By comparing data to a set of known control points users can explore the parameters of the most likely candidates quickly and accurately. Projection recovery is perhaps most applicable to raster data in that it is quite common for raster data to lose its associated projection information.  Use the Projection Recovery Tool to conduct an automated statistical analysis of your data to produce a quick list of the most likely candidate projections for your data.  No more need for manually assigning and guessing at projections.  This process will save time and money when working with data with lost projection information by automatically doing the comparison for you. The Georeferencing tool within the Geographic Transformer allows users to assign coordinates to an image through an easy to use point selection tool to locate the image in the world. Once an image has been georeferenced, it can be transformed to any other appropriate projection for display in other GIS software.

“We are excited about this software in that we know it will save our users time and money,” stated Blue Marble President Patrick Cunningham.  “Like many of our customers there are many times when we have to sift through data trying to determine the projection information.  This tool does that for you.  The time and thus cost savings are immediate.”
