Step 2: Validate

Overview

Tool: Online validator

Performed by: external consultants

Maintained by: KfW Team Data Analytics & Artificial Intelligence (DAI)

Previous step: 1 Collect

Next step: 3 Visual plausibility check

Purpose

Validate Project Location data from the Collect step. A successful validation produces a GeoJSON file with a timestamp and unique filename.

Requirements

Procedure

  1. Upload the project-level locations file on the online validator website by selecting the blue File Upload button.

  2. Review the validation result on the screen. A failed screening will result in validation errors (red background) indicating the data row where the error occurs in the PLM and a short message describing the type of error - please see examples below. In these cases, please correct the errors and upload the updated file for validation again.

  3. If validation passes, the Download GeoJSON button will change from grey to blue (active). A GeoJSON file with a unique timestamp and filename is generated.

Examples of validation results

Validation errors

  • No Project Locations displayed on the map or displayed incorrectly
  • GeoJSON will not be generated; Download GeoJSON button remains grey (disabled)

Review error messages in the validator and correct source data in the PLM before re-validating.
