FAQ
B to IGS Conversion
What are B files?
.b is a specialized binary grid format developed by the National Geodetic Survey (NGS) of the National Oceanic and Atmospheric Administration (NOAA) to distribute coordinate transformation grids for GEOCON and NADCON 5.0 workflows. Designed originally by Dennis Milbert to standardize geoid and datum shift manipulations, a file of this type contains spatial coordinate corrections (latitude, longitude, or ellipsoidal height offsets) stored as continuous gridded records. The format features a unique structural characteristic rooted in its legacy FORTRAN generation: every data record is wrapped within leading and trailing 4-byte buffer artifacts that specify record length. A single .b file typically stores only one components of a three-dimensional transformation—such as latitude shifts—requiring complementary companion files with identical structures to fully execute a high-precision datum conversion across regions of the National Spatial Reference System (NSRS).
What are IGS files?
The IGS (Initial Graphics Exchange Specification) file format is a standardized CAD data exchange format used to transfer 2D and 3D model data between different CAD systems. Developed in the 1980s, IGES ensures compatibility across various engineering and design software by storing geometric data, annotations, and structure in a neutral ASCII or binary format.
Can reaConverter convert B to IGS?
Yes! reaConverter instantly converts .b to .igs with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.
What is reaConverter used for?
reaConverter is a Windows converter for 800+ formats, GIS data among them. For B to IGS it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.
Why choose offline conversion with reaConverter?
reaConverter is a software program that is used for offline files conversion. Your proprietary documents never leave your computer – essential for architects, engineers, healthcare and government contractors handling classified projects. Meets GDPR, HIPAA, CCPA, and corporate security policies by ensuring files never cross borders or third-party systems.
