An XYZ file is a plain text format used to store 3D point cloud data. Each line in the file typically represents a single point in 3D space, defined by:

X: Horizontal coordinate (e.g., easting or longitude)

Y: Vertical coordinate (e.g., northing or latitude)

Z: Elevation or depth (typically in meters)

- X: Horizontal coordinate (e.g., easting or longitude)
- Y: Vertical coordinate (e.g., northing or latitude)
- Z: Elevation or depth (typically in meters)

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

The file extension must be <code>.xyz</code>, <code>.pts</code>, <code>.dat</code>, <code>.csv</code> or <code>.txt</code>

Each line must consist of three numeric values, with the decimal point represented by a <code>.</code>

Values must be space-separated, comma-separated, semi-colon or tab-separated

An optional header line can be provided in one of the following forms: <code>X Y Z</code>, <code>'X' 'Y' 'Z'</code> or <code>“X” “Y” “Z”</code>

- Must be an ASCII text file
- The file extension must be <code>.xyz</code>, <code>.pts</code>, <code>.dat</code>, <code>.csv</code> or <code>.txt</code>
- File Encoding UTF-8
- Each line must consist of three numeric values, with the decimal point represented by a <code>.</code>
- Values must be space-separated, comma-separated, semi-colon or tab-separated
- An optional header line can be provided in one of the following forms: <code>X Y Z</code>, <code>'X' 'Y' 'Z'</code> or <code>“X” “Y” “Z”</code>

ASCII-XYZ files do not inherently include Coordinate Reference System (CRS) information. Therefore:

If your data uses geographic coordinates, it will automatically be interpreted using the WGS84 CRS (EPSG:4326).

Including a sidecar <code>.prj</code> file specifying the CRS

If the CRS is not evident from the file, you can manually specify the CRS after upload. Note that this does not alter the file but allows the platform to properly index it.

- Sonarwizz
- Beamworx
- Qimera
- Fledermaus
- CARIS

File extension must be <code>.xyz</code>, <code>.pts</code>, <code>.dat</code>, <code>.csv</code> or <code>.txt</code>

Each line has exactly three numeric values

Values are separated by space-separated, comma-separated, semi-column or tab-separated

CRS is known and specified in a <code>.prj</code> sidecar file during upload

- File is in plain ASCII text format
- File extension must be <code>.xyz</code>, <code>.pts</code>, <code>.dat</code>, <code>.csv</code> or <code>.txt</code>
- Each line has exactly three numeric values
- Values are separated by space-separated, comma-separated, semi-column or tab-separated
- Values contain <code>.</code> decimals
- CRS is known and specified in a <code>.prj</code> sidecar file during upload

If your preview does not show as expected:

Double-check the file for the above issues

1. Double-check the file for the above issues
2. Confirm the coordinate system used
3. Contact our support team with:
   - A sample of your file
   - CRS details
