New Features of Didger 5: Expanded Projection Library

Another new feature of Didger 5 is an expanded projection library that supports more coordinate systems, projections, and datums than ever before. No more setting the projection/coordinate system for each file during the import process; now all files are re-projected on-the-fly and will seamlessly integrate with or match the current project's projection/coordinate system!


New coordinate systems, projections, and datums that have been added include:
