About .gsa Files
GSA files are plain text files that store NTv2 Standard ASCII Grid Shift data. They contain grid shift values used in transforming geographic coordinates between different datums.
These files are often used by geospatial and mapping software. Editing or viewing them can be done with simple text editors, though specialized tools like GDAL, QGIS, or ArcGIS also use them to ensure precise coordinate conversions.
- Coordinate Transformation: They provide shift values needed to adjust maps and survey data.
- Plain Text Format: Being text-based makes them easy to inspect and modify for troubleshooting.
- Geodesy and Mapping: They help maintain accurate spatial relationships when converting between datums.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
