# SNAP_TIFF -- Sentinel Application Processing GeoTIFF

Added in version 3.10.

Driver short name

SNAP_TIFF

Driver built-in by default

This driver is built-in by default

This driver deals specifically with GeoTIFF files produced by the Sentinel Application Processing (SNAP) toolbox.

Such files are formulated in a way that makes it difficult to read them with the generic GTiff -- GeoTIFF File Format driver.

## Driver capabilities

Supports Georeferencing

This driver supports georeferencing

Supports VirtualIO

This driver supports virtual I/O operations (/vsimem/, etc.)

## Georeferencing

SNAP GeoTIFF files contain a geolocation array (stored as a regular grid of GeoTIFF tie points). It is reported in the `GEOLOCATION` metadata domain.

The 4 corners of the geolocation array are also reported as ground control points for faster (but less accurate) georeferencing.

## Metadata

Extensive metadata following DIMAP conventions is reported in the `xml:DIMAP` metadata domain.
