OGC GeoTIFF Standard is an OGC Implementation Standard. GeoTIFF is based on the TIFF format and is used as an interchange format for georeferenced raster imagery. GeoTIFF is in wide use in NASA Earth science data systems.
There are other scientific file formats that are well established within the NASA community, such as HDF5 and netCDF. However, there is continued interest and demand for the GeoTIFF file format, mostly as a distribution format for satellite or aerial photography imagery and for other kinds of data such as Digital Elevation Model (DEM) data and Digital Ortho Quadrangle data.
Status
OGC GeoTIFF 1.1 is an approved NASA Earth Science Data Systems standard.
NASA ESDIS recommends the use of Cloud Optimized GeoTIFF (COG) for any data distribution that would be appropriate for a traditional GeoTIFF. COG files are fully backward compatible with all tools that are used in the reading of GeoTIFFs. Using COG files allows those with access to cloud-based computing environments to have all the benefits of the expanded COG format without limiting those still using traditional tools.

NASA Earth Science Community Recommendations for Use
Strengths
The GeoTIFF file format is in widespread use worldwide. NASA DAACs provide data in GeoTIFF format as do other NASA Earth science data providers. There is strong software support in the form of the open source libgeotiff library and Geospatial Data Abstraction Library (GDAL) package. Many commercial GIS and spatial data analysis software products support reading and writing GeoTIFF data.
Weaknesses
While the GeoTIFF format provides for a tremendous amount of interoperability as evidenced by its widespread use within NASA and elsewhere, there is room for further discussion about how to increase interoperability. Work on this topic continues in NASA's Dataset Interoperability Working Group (DIWG) as part of the larger Earth Science Data System Working Group effort within NASA's ESDIS Project.
Applicability
The GeoTIFF file format was developed primarily as a distribution format for satellite or aerial photography imagery as well as for other kinds of data such as Digital Elevation Model (DEM) data and Digital Ortho Quadrangle data.
Limitations
GeoTIFF is not necessarily suitable for every data type. There are other scientific file formats that are well established within the NASA community, e.g., HDF5 and netCDF, that are approved for use in NASA Earth science data systems.
GeoTIFF is not suitable for storing complex multi-dimensional data structures nor for storing vector data with many attributes or topology information.
