Meridian QGIS Pro Workflows

Executed worked example: inspection assets

This is synthetic data, executed on 2026-10-14 in an isolated QGIS 4.0 runtime using Meridian's real bridge handlers. It is not a customer case study or an independent security certification. Inputs and acceptance rules were intentionally simple so that the full result is reproducible and inspectable.

Request

Audit the 12 inspection assets for nonblank unique asset IDs and scores between 0 and 100. Preserve the original dataset. On a durable copy, trim and uppercase the status field. Create 25-metre buffers in EPSG:32734 and deliver a saved project with an evidence report.

Audit outcome

Complete attribute coverage: 12 features across three pages of five, five, and two records. The three issues remain findings; status normalization does not repair identifiers or scores.

Geometry validity and positional accuracy were not audited in this example; its points and locations are generated. The CRS was deliberately chosen as a metre-based projected system for a synthetic demonstration, not as a universal recommendation.

Cleanup outcome

Created cleaned.gpkg from source.gpkg and compared its twelve attribute rows with the source before editing. Normalized only status; no geometry writes were performed.

Four rows changed; eight were already normalized. All twelve statuses were re-read as GOOD. The original's twelve attribute rows were re-read and unchanged. The missing/duplicate IDs and out-of-range score remain explicitly unresolved.

Processing outcome

Inspected native:savefeatures and native:buffer in the installed registry. Buffer enum labels were checked against the installed parameter definitions: end caps Round/Flat/Square and joins Round/Miter/Bevel.

native:buffer used distance 25, segments 12, round end caps and joins (enum value 0), miter limit 2, and dissolve false. The durable buffer-25m.gpkg output loaded successfully with 12 polygon features in EPSG:32734. This verifies parameter use, readability, count and CRS; it is not a separate numerical boundary-accuracy test.

Handover outcome

Saved handover.qgz referencing the original, cleaned copy, and buffers. A separate QgsProject instance reopened that file without replacing the active project and confirmed all three layers were valid. Captured the QGIS canvas as a PNG.

Delivered files: source.gpkg, cleaned.gpkg, buffer-25m.gpkg, handover.qgz, map.png, and the execution evidence JSON. The project depends on the three GeoPackages remaining available; this is not proof of relocation portability or an offline service bundle.

Apply to another project

Use the four workflow references for a new dataset. Discover algorithms and enums in that user's installed QGIS version, select a CRS for their real geographic area, verify copied IDs, and preserve their authorization and output paths. These counts and results are evidence for this synthetic example only.
