{ "releaseId": "terra-geobenchx-v1", "taskId": "968087", "question": "Generate a heatmap of earthquake occurrences near railway lines in Canada.", "submittedPrompt": "Generate a heatmap of earthquake occurrences near railway lines in Canada.\n\nTask conventions: Use the original point and line fixtures with the following precise near-rail convention. Select original earthquake points at planar distance strictly less than 10,000 metres from original railway features whose COUNTRY is CA. Transform original vertices to EPSG:3978 (Canada Atlas Lambert); segments are straight in that projection, with no densification. This explicitly fixes the archived reference's unspecified 10 km buffer projection; it is not an exact geodesic or travel-distance measurement. Include points near Canadian rail even if across an international boundary, matching the railway-buffer selection. Use one unit per event to show occurrences, not magnitude weights: the frozen event file contains negative magnitudes, so this is an explicitly disclosed count-weight adaptation of the archived heatmap. Use original January–February 2025 events, not current earthquakes. Use original point records and the declared attribute/raster selection; do not infer a separate geographic boundary. Unknown country indicators, nonpositive ratio denominators, missing geometry and missing/nonfinite weights are unknown, not zero. Known zero weights remain valid. Exclude valid points outside the specified geography. Include only eligible points with a finite nonnegative weight in the contributing artifact; report other potentially eligible points as unknown. Use this explicit geographic heatmap convention: grid={\"bounds\": [-18000000, -7325000, 18000000, 7325000], \"crs\": \"EPSG:6933\", \"resolutionX\": 25000, \"resolutionY\": 25000}, radius 150000 metres = three Gaussian standard deviations. First bin each point into its containing grid cell and sum its weight. Smooth using a normalized separable Gaussian, numerical support four standard deviations, constant-zero exterior; do not renormalize edges. Use both grid resolutions for the two axes; keep original grid alignment. This is a declared metric raster adaptation to the original interactive screen-pixel heatmap, not an equivalent zoom-dependent rendering. Output unit: events per grid cell. Zero cells are valid; this is not density per square kilometre. Do not rescale the values for presentation.\n\n\n\nAdd the heatmap raster to the map and retain an inspectable selected-point artifact with original geometry and benchmark_row_id. End with one fenced JSON object: {count: contributing point records, unknown_count: records with unknown eligibility or weight, unlocated_count: original points lacking valid geometry, coverage_note: string, selection: {collectionId,itemId,assetKey}, density: {collectionId,itemId,assetKey}, map_layer_id: heatmap_layer_id}. Explain the data edition, numerical weights, grid, smoothing and coverage limitations. The source-point artifact is not itself the requested heatmap.\n\nDelivery format: provide the answer object with all fields specified above as final_response on assess_result, alongside the inspected final artifact_refs. This replaces the JSON-code-block formatting requirement above. Blue attaches your explicit selection to the accepted final answer. Finish with a concise ordinary-language answer agreeing with that selected result; do not duplicate the JSON in chat.\n\nSupplied immutable inputs:\n[\n {\n \"name\": \"Earthquake points, frozen 30-day snapshot\",\n \"edition\": \"Archive labelled Feb142025; observed event timestamps 2025-01-16 through 2025-02-15 UTC\",\n \"units\": {},\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n },\n {\n \"name\": \"North American Rail Network Lines, frozen GeoBenchX snapshot\",\n \"edition\": \"Original pinned GeoBenchX NARN/FRA/BTS snapshot, not a live network\",\n \"units\": {},\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n }\n]", "finalAnswer": "Done — the heatmap is on the map, and I kept the selected earthquake points with original geometry and `benchmark_row_id` for inspection.\n\nIt uses 16 archived Jan–Feb 2025 earthquake events near rail features with `COUNTRY=CA`, with 0 unknown-eligibility records and 0 unlocated source points.\n\nImportant limitation: this is based on the frozen USGS earthquake snapshot labeled Feb142025 and the frozen GeoBenchX NARN/FRA/BTS rail snapshot, using the declared EPSG:3978 strict `<10 km` planar rule and a fixed EPSG:6933 smoothed raster in events per 25 km cell — not current earthquakes, not geodesic distance, and not the old zoom-dependent screen heatmap.\n\nNext: inspect the saved points and the map layer, or ask me for an export or an unsmoothed version.\n\n### Limitations\n\n- Uses the supplied frozen earthquake snapshot labelled Feb142025 with observed event timestamps 2025-01-16 through 2025-02-15 UTC and the original pinned GeoBenchX rail snapshot, not current data.\n- Near-rail selection follows the declared EPSG:3978 planar <10000 metre convention on original transformed vertices with straight segments and no densification; it is not geodesic or travel distance.\n- The heatmap is a fixed EPSG:6933 metric raster with 25000 metre cells and Gaussian smoothing radius 150000 metres; values are events per grid cell and the display is not zoom-dependent screen rendering.\n- Uses the archived earthquake snapshot labelled Feb142025 with observed event timestamps 2025-01-16 through 2025-02-15 UTC and the frozen GeoBenchX rail snapshot, not current data.\n- Near-rail means strict planar distance less than 10000 metres in EPSG:3978 on original transformed vertices with straight segments and no densification; it is not geodesic, travel, or engineering distance.\n- The heatmap is a fixed EPSG:6933 metric raster with 25000 metre cells and Gaussian smoothing radius 150000 metres; values are events per grid cell, not density per square kilometre, and the display is not the original zoom-dependent screen heatmap.", "checks": { "expectedCount": 16, "actualCount": 16, "expectedMetrics": null, "actualMetrics": null, "computationCorrect": true, "answerFulfilled": true, "adjudication": null, "qualification": null, "reasons": [] }, "activity": [ { "at": "2026-10-07T08:19:39.631126Z", "title": "Progress update", "detail": "I’m checking the saved analysis context, the map state, and the exact source/processor options so I can build the heatmap with the requested fixed projection and grid rules." }, { "at": "2026-10-07T08:19:51.190602Z", "title": "Progress update", "detail": "I found the Blue analysis tools.
