{ "releaseId": "terra-geobenchx-v1", "taskId": "435973", "question": "Generate a heatmap of power station density in regions with water scarcity", "submittedPrompt": "Generate a heatmap of power station density in regions with water scarcity\n\nTask conventions: Use supplied countries with CONTINENT=Africa. Scarcity is the benchmark proxy of WDI ER.H2O.FWTL.ZS 2021 withdrawals at least 100% of internal freshwater resources. Weight stations by DsgAttr02 MW, a capacity-weighted heatmap, not a count or proof of current generation. Use original point records strictly within the original selected country polygons; no clipped polygons, location guesses or current data. Join country ISO_A3 to the supplied indicator table's Country Code exactly. 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: sum of MW 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\": \"African power stations\",\n \"edition\": \"USGS 2021 frozen compilation\",\n \"units\": {\n \"DsgAttr02\": \"MW\"\n },\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n },\n {\n \"name\": \"World Bank country boundaries\",\n \"edition\": \"GeoBenchX harmonized names\",\n \"units\": {},\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n },\n {\n \"name\": \"Freshwater withdrawals as percent of internal resources\",\n \"edition\": \"Frozen World Development Indicators; use 2021\",\n \"units\": {\n \"2021\": \"percent of internal freshwater resources\"\n },\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n }\n]", "finalAnswer": "Done — the heatmap is on your map, and I kept the inspectable selected-point artifact with original geometry and benchmark_row_id.\n\nIt uses the frozen USGS 2021 power-station compilation, weighted by DsgAttr02 MW, and the frozen WDI 2021 country benchmark on the fixed EPSG:6933 25 km grid with 150 km Gaussian smoothing.
