资源简介：
This report serves as documentation for NADCON version 5.0, a comprehensive rebuild and replacement for all versions of NADCON and GEOCON and their respective transformations. This rebuild focused on three areas: 1) improving how users interface with NGS datum transformation software, 2) correcting known bugs and scientific issues with the existing software, and 3) preparing for the replacement of NAD 83 in 2022. For the NADCON 5.0 release provided with this report, 44 separate transformations (30 latitude/longitude, 14 ellipsoid height) were computed in 9 different regions.
