Earth Map Suite Codegen

Codegen status

このページは metadata-only endpoint の呼び出し例だけを扱います。ラスター/COG pixel sampling のコードは未検証のため生成しません。

Guardrails

metadata-only response only
do not treat synthetic preview as observed precipitation
do not generate raster sampling code here
keep endpoint errors visible

Endpoint

/api/earth-map-suite/precipitation?bbox=139.5,35.4,140.0,35.9&start=2025-08-01&end=2025-08-03&preset=low

JavaScript fetch example

const params = new URLSearchParams({
  bbox: '139.5,35.4,140.0,35.9',
  start: '2025-08-01',
  end: '2025-08-03',
  preset: 'low'
});

const response = await fetch(`/api/earth-map-suite/precipitation?${params}`, {
  headers: { accept: 'application/json' }
});
const payload = await response.json();

if (response.ok && payload.status === 'ok' && payload.sampling_status === 'metadata_only') {
  console.log('metadata reachable', payload.dataset_id, payload.matched_dates);
} else {
  console.warn('metadata unavailable', payload.error_code, payload.message);
}
