Introduction
Ensuring the quality and accuracy of your scans is crucial to the scan - blockmodel conformation process. Below, the detailed guidelines are listed to help you prepare your scans appropriately for efficient ingestion and processing.
1. File Formats
Accepted Formats: Ensure your scans are saved as one of the following formats
.csv,.txt,.dxf,.str,.laz, or.las.Excluded Formats: Please refrain from using any software-specific formats i.e
.msr.Importance: Critical
2. One Topography Scan Per File
Guideline: Your submitted file should only contain one topography scan. Including multiple scans in a single file hampers the automation process.
Importance: Mid
3. Full Stockpile Scan Per File
Guideline: Each scan you submit should fully cover the stockpile, regardless of any material movement.
Reference: For reference, consult Appendix B, Examples 1 & 2 for scans that don't cover the entire stockpile.
Importance: Critical
4. Single Surface Scan Per File
Guideline: Ensure that your file only contains the current surface scan. The inclusion of previous scans or underlying bench topography in the same file is not acceptable.
Reference: Check out Appendix B, Example 3 for a file containing multiple scans.
Importance: High
5. Consistent X and Y Range; Fixed Minimum Z Value
Guideline: For a particular stockpile, the XY area covered by the scan should remain consistent across different scans. While the minimum Z value must remain fixed, the maximum Z value can vary between files.
Importance: Mid
6. File Naming Convention
Guideline: Your file name should clearly and uniquely identify the scan's date, time, and the stockpile's name. While we accept various date/hour formats, maintain consistency across all files.
Example:
2020-01-13T10-30-00_STOCKPILES.csv— This file represents scans for multiple stockpiles (STOCKPILE_A, STOCKPILE_B, STOCKPILE_C, etc) dated 2020-01-13 at 10:30:00 UTC time.Example:
2022_10_28_19_48_00_STOCKPILES_2.dxf— This file denotes scans for multiple stockpiles (STOCKPILE_E, STOCKPILE_F, etc) dated 2022-10-28 at 19:48:00 UTC time.
Importance: Critical
7. Consistent Grid and Origin for Stockpiles
Guideline: To ensure the accurate reconciliation of models and scans, each stockpile should have a consistent grid and origin between scans. Even small offsets in X and Y can create discrepancies.
Importance: High
8. Scan Resolution
Guideline: The spatial resolution of your scan should exceed the resolution you intend to convert it to. For instance, if we're to generate block models with a resolution of 5.0m, we'd expect scans to possess more points than a 5.0m resolution. However, 5cm resolution scans might not be optimal due to storage and processing requirements.
File Size Limit: We accept scans up to a maximum size of 1.5GB.
Importance: Mid
Conclusion
Adhering to these guidelines ensures efficient processing of your scans. Always review these specifications before submission to guarantee accurate and timely results. If you have further queries or need assistance, please reach out to our support team.
