XYZ format - PIX4Dfields

Introduction

The XYZ format is available under the Water Management in PIX4Dfields. This format allows the exporting of a text file containing XYZ information derived from the Digital Surface Model (DSM).

For the best results, it is recommended to use Accurate Processing when processing the drone images, to generate a high-resolution DSM before exporting. 

Steps to export an XYZ File

1. Go to Export.
2. Select Water Management.
3. Select the DSM from your project.
   

   

4. Choose the Coordinate Reference System (CRS):
   
   • Projected (UTM)
     • Exports the X, Y, Z coordinates in meters (Easting, Northing, and Elevation).
   • Geographic
     • Exports Latitude and Longitude in degrees, with Elevation in meters.
5. Adjust the grid resolution (e.g., 0.5 m – 10 m) to control the level of detail in your exported file. 1m is comparable to Lidar surveys, start with 3m if you don't know the limits of the receiving software.
6. Check the estimated number of points and file size before exporting.
7. Export the XYZ file for use in other GIS applications.
   
   

Common Software Compatibility

The formatted XYZ file will be compatible with major agricultural grading software including:

• Trimble AG
• OptiSurface
• Ezigrade.
• AGForm-3D.
• Multiplane.

OptiSurface compatible 

To make the .txt exported compatible with OptiSurface:

1. Open the file.
2. Change the extension to ".ags"
   
   
3. Click Save.
