Causes and Solutions for the Misalignment of 'Surfer' Data — Correct Settings for the Coordinate System
Introduction When creating maps with Surfer, you may encounter issues such as "the loaded data is displayed in a completely different location on the map" or "the position shifts when multiple layers are overlaid." Many of these problems stem from mistakes in the coordinate system settings. In this article, we will explain why these discrepancies occur and provide step-by-step instructions on how to set it up correctly. Why do data positions shift? The method of representing locations on Earth numerically varies significantly depending on "which coordinate system is used." For example, even for the same location (Tokyo Tower)...

basic information
Common patterns of discrepancies: - Mixed domestic GPS data (JGD2011) with old geodetic system data → discrepancies of tens to hundreds of meters - Read latitude and longitude data as planar rectangular coordinates → displayed in completely different locations - Created a map without setting any coordinate system → layers do not align with each other
