{ "releaseId": "terra-geobenchx-v1", "taskId": "131687", "question": "Generate contour lines of snow accumulation near major US lakes", "submittedPrompt": "Generate contour lines of snow accumulation near major US lakes\n\nTask conventions: Use band 1 of the frozen snow raster at the original grid without resampling, smoothing or clipping. Draw the explicit contour levels [5, 10, 20, 40, 80, 160, 320] in inches. These levels are a disclosed evaluation convention, not a requested interval. Use piecewise-linear marching-squares isolines through pixel-center values, low-valued connectivity at ambiguous saddles. Respect the native mask, NoData and nonfinite cells; do not bridge holes or extrapolate at the outside edge. Apply any source scale and offset. NoData means unknown, never zero. Preserve source coverage; levels outside the observed range may have no line. Do not substitute a current raster. Count nonempty requested contour LEVELS, not polyline fragments. The population-count raster, where supplied, is people per original cell; do not label it population density. Overlay the supplied na_lakes original geometries on the same map. Retain original overlay features matching predicate intersects against each original countries polygon selected by NAME_EN='United States'; duplicated matches count once. Do not clip the line geometries. A dissolved union of the selected country polygons is equivalent for intersects. This is a visual spatial comparison; no invented causal correlation or extra buffer is requested. As in the released reference, near means visual comparison on the same map, not an invented proximity buffer. Major water bodies means the supplied CEC inventory, not an added size threshold. The seven explicit levels replace the reference's dense five-inch interval as a disclosed presentation convention. Keep the actual 2024-09-30 to 2025-05-20 season, not the reference's stale February plot title. Water data and derived maps are for this benchmark only.\n\n\n\nDeliver an inspectable vector contour artifact and add it to the map with a level/units legend. End with one fenced JSON object containing: count (number of nonempty requested levels), unknown_count (number of masked or nonfinite source pixels), coverage_note, selection: {collectionId,itemId,assetKey}, level_field, feature_count (actual contour feature rows), map_layer_id. Also include overlay: {selection: {collectionId,itemId,assetKey}, map_layer_id, count}, retaining original benchmark_row_id. Explain the source season/year, units, missing coverage, and visual relationship where an overlay is requested.\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\": \"US snowfall, 2024\\u201325 frozen season\",\n \"edition\": \"2024-09-30 to 2025-05-20\",\n \"units\": {\n \"band1\": \"inches\"\n },\n \"collectionId\": \"blue-generated--[resource id withheld]\",\n \"itemId\": \"[resource id withheld]\",\n \"assetKey\": \"data\"\n },\n {\n \"name\": \"North American lakes, CEC 2023 frozen benchmark source\",\n \"edition\": \"CEC North American Environmental Atlas version 4.0 (2023), original benchmark snapshot; benchmark-only use\",\n \"units\": {},\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]", "finalAnswer": "Done — I added the 2024‑09‑30 to 2025‑05‑20 snowfall contours in inches and the original CEC lake overlay to your map.
