可視區域
經緯度可視區域，以兩個對角相反的 low 和 high 點表示。可視區域視為封閉區域，也就是包含邊界。緯度範圍必須介於 -90 到 90 度之間 (含首尾)，經度範圍則需介於 -180 到 180 度之間 (含首尾)。各種情況包括：
如果 low = high，可視區域就會包含該單一點。
如果 low.longitude > high.longitude，經度範圍會反轉 (可視區域會跨越 180 度經線)。
如果 low.longitude = -180 度，且 high.longitude = 180 度，則可視區域會包含所有經度。
如果 low.longitude = 180 度且 high.longitude = -180 度，則經度範圍為空白。
如果 low.latitude > high.latitude，則緯度範圍為空白。
low 和 high 都必須填入資料，且代表的方塊不得為空白 (如上述定義所述)。空白的檢視區會導致錯誤。
舉例來說，這個視區會完全包含紐約市：
{ "low": { "latitude": 40.477398, "longitude": -74.259087 }, "high": { "latitude": 40.91618, "longitude": -73.70018 } }
