What is a .grd file?

A .GRD file is a grid data file format primarily associated with Golden Software's Surfer software. Surfer is a powerful contouring, gridding, and surface mapping program widely used in earth sciences, engineering, and other fields. GRD files store regularly spaced or irregularly spaced data points representing a surface. These data points typically contain X, Y, and Z values, where X and Y represent the coordinates and Z represents the value at that location (e.g., elevation, temperature, concentration). The grid structure allows Surfer to efficiently create contour maps, surface maps, and other visualizations. The format can store various types of gridded data, including digital elevation models (DEMs), geophysical data, and environmental data. GRD files can be created by Surfer itself through gridding algorithms applied to raw data or imported from other data sources. The format supports different grid structures and data types, allowing for flexibility in representing various types of surfaces. The data is often stored in a binary format for efficiency, but some variations of the GRD format may use ASCII encoding. The GRD format is a proprietary format, but it is well-documented and widely supported by other GIS and scientific software packages.
