A GeoTIFF is a geo-referenced raster image format that embeds geographic metadata directly within a standard TIFF file. This allows raster data (e.g., satellite imagery, elevation models, seabed maps) to be correctly positioned in geographic space.

Elevation or depth models (DEM/DTM)

- Grayscale or RGB imagery
- Elevation or depth models (DEM/DTM)
- Classification maps
- Backscatter intensity

To be compatible with our preview and processing tools, your file must meet the following requirements:

Must be a valid GeoTIFF file (TIFF format with embedded georeferencing metadata)

File extension must be <code>.tif</code> or <code>.tiff</code>

- CRS information (via embedded GeoTIFF tags or <code>.tfw/.prj</code> sidecar files)
- Pixel values in one or more bands (e.g., 1 for grayscale, 3 for RGB, 1 Alpha band for transparency)

Compression is allowed (LZW or DEFLATE preferred), but uncompressed files are also supported

- Must be a valid GeoTIFF file (TIFF format with embedded georeferencing metadata)
- File extension must be <code>.tif</code> or <code>.tiff</code>
- Must include:
 - CRS information (via embedded GeoTIFF tags or <code>.tfw/.prj</code> sidecar files)
 - Pixel values in one or more bands (e.g., 1 for grayscale, 3 for RGB, 1 Alpha band for transparency)
- Compression is allowed (LZW or DEFLATE preferred), but uncompressed files are also supported

A DEM file exported as <code>elevation.tif</code> with embedded EPSG:32633

A backscatter mosaic with 1-band 8-bit grayscale values and CRS

A 3-band RGB image (GeoTIFF with EPSG:4326) showing satellite imagery

- A DEM file exported as <code>elevation.tif</code> with embedded EPSG:32633
- A backscatter mosaic with 1-band 8-bit grayscale values and CRS
- A 3-band RGB image (GeoTIFF with EPSG:4326) showing satellite imagery

TIFF file without any geo-referencing tags

Raster with missing <code>.prj</code> or <code>.tfw</code> files (if CRS is not embedded)

- TIFF file without any geo-referencing tags
- Raster with missing <code>.prj</code> or <code>.tfw</code> files (if CRS is not embedded)

GeoTIFF files should embed the CRS via internal metadata. If not, provide a sidecar file:

A <code>.prj</code> file (WKT format) for CRS

A <code>.tfw</code> file (world file) for geo-referencing, if CRS is not embedded

- A <code>.prj</code> file (WKT format) for CRS
- A <code>.tfw</code> file (world file) for geo-referencing, if CRS is not embedded

Note: If the CRS is missing or unclear, you can manually assign the correct EPSG code after upload for correct preview and indexing.

This format is supported when exported from the following software packages:

Hydrographic / MBES &amp; SSS-Focused Tools

- Sonarwizz
- Beamworx
- Qimera
- Fledermaus
- CARIS

File is in GeoTIFF format (<code>.tif</code> or <code>.tiff</code>)

File includes embedded geo-referencing and CRS

Pixel values are appropriate for the data type (e.g., 16-bit for elevation, 8-bit for RGB)

Optional <code>.prj</code> or <code>.tfw</code> files are provided if CRS is not embedded

Image has no extraneous transparency band unless required

- File is in GeoTIFF format (<code>.tif</code> or <code>.tiff</code>)
- File includes embedded geo-referencing and CRS
- Pixel values are appropriate for the data type (e.g., 16-bit for elevation, 8-bit for RGB)
- Optional <code>.prj</code> or <code>.tfw</code> files are provided if CRS is not embedded
- Image has no extraneous transparency band unless required

If your preview does not show as expected:

Ensure the file includes valid geo-referencing

Confirm the correct CRS is embedded or provided in a <code>.prj</code> file

1. Ensure the file includes valid geo-referencing
2. Confirm the correct CRS is embedded or provided in a <code>.prj</code> file
3. Contact our support team with:
 - A sample of your file
 - CRS details
