Summary
Customers can download historical probe data from HERE Platform Data Catalogs using the OLP CLI. This article explains how to retrieve partitioned data from a shared catalog and clarifies expected behavior when accessing historical data.
---
Answer
Historical probe data stored in HERE Platform catalogs can be accessed using the OLP CLI by retrieving partitions from a specific layer.
To download data:
Identify the catalog HRN and layer ID
Use the OLP CLI command with a valid filter and credentials
Ensure access permissions to the shared catalog
This approach is intended for bulk data retrieval from partitioned layers.

Recommended Actions
1. Install OLP CLI
Follow official documentation:
Install OLP CLI
---
2. Identify Required Parameters
Log in to HERE Platform
Navigate to Data Catalog
Locate the shared probe data catalog
Capture:
+ Catalog HRN
+ Layer ID
---
3. Execute Data Retrieval Command
olp catalog layer partition get
--filter "timeWindow >= 0"
--credentials
Replace:
→ Catalog identifier
→ Target layer
→ Local credentials file path
---
4. Validate Credentials
Ensure your credentials file is valid and linked to a HERE project
If missing, generate credentials via HERE Platform
---
5. Apply Meaningful Filters (Recommended)
Instead of using broad filters like:
timeWindow >= 0
Use targeted filters to limit data volume and improve performance (based on your dataset structure).
---
Notes
Data in HERE Platform is partition-based, not file-based
Large datasets require filtered queries for efficient retrieval
The timeWindow filter depends on dataset schema and may not apply to all layers
CLI retrieves raw partition data; further processing may be required
