这两种表示法包含相同的位置和准确性。例如，如果出价请求使用城市级精度填充 BidRequest.device.geo，则 lat 和 lon 字段将包含所标识城市中心点的纬度和经度，而 accuracy 将是与该城市面积相同的圆形的半径。Google 还将 lat 和 lon 字段的精度限制为 0.01 度。
地理位置定位最佳实践
对于需要自定义地理位置数据的出价方，我们建议使用近似的 lat、lon 和 accuracy 字段来执行空间地理位置查询。我们不建议使用 BidRequest.device.ip 字段进行地理定位，因为 Google 只会以截断形式分享 IP 地址；使用截断的 IP 地址进行地理定位可能会导致结果不太准确。
