Running Bulldozer

Prerequisites

Before running Bulldozer, ensure that your input data meets the following requirements: - The DSM is consistent and free from major artefacts. - nodata value is properly defined in the DSM metadata. - The Coordinate Reference System (CRS) is correctly specified in the DSM metadata. - The spatial resolution of your DSM matches your requirements.

If any of these conditions are not satisfied, please refer to the Input Data Preprocessing page before proceeding.

Note
The reliability and accuracy of the generated DTM are directly dependent on the quality of the input DSM.

Bulldozer interfaces

Bulldozer can be executed using several interfaces, depending on your workflow:

• Command-Line Interface (CLI)
• Python API
• Docker image

For a complete description of available optional parameters, see the Bulldozer parameters page.

After execution, the list and description of output products are available on the Bulldozer Outputs page.

When to use CLI vs Python API?

Use case	Recommended interface
Quick processing	CLI
HPC batch jobs	CLI + config file
Interactive analysis	Python API
Integration into a larger Python pipeline	Python API
