扩大覆盖范围（实验性）

欧洲经济区 (EEA) 开发者

Solar API 将推出一项实验性功能，该功能基于应用于卫星图像的机器学习模型，将覆盖范围扩大到之前不支持的地区。如需访问实验性太阳能数据，请将 experiments 参数设置为 EXPANDED_COVERAGE，并将 requiredQuality 参数设置为 BASE。

实验数据适用于 buildingInsights 和 dataLayers 请求。以下部分介绍了示例请求和响应。

构建数据分析

buildingInsights 端点可提供有关建筑物位置、尺寸和太阳能潜力的分析。如需请求建筑洞见，请向以下网址发送 HTTP GET 请求：

https://solar.googleapis.com/v1/buildingInsights:findClosest?key=YOUR_API_KEY

添加请求网址参数，用于指定位置的纬度和经度坐标，以及结果中允许的最低必需质量级别。

以下示例请求获取纬度 = 4.655719 和经度 = -74.128971 的位置的建筑洞见信息。如需请求实验数据，请设置以下参数：

  • requiredQuality = BASE
  • experiments = EXPANDED_COVERAGE
curl -X GET "https://solar.googleapis.com/v1/buildingInsights:findClosest?location.latitude=4.655719&location.longitude=-74.128971&requiredQuality=BASE&experiments=EXPANDED_COVERAGE&key=YOUR_API_KEY"

该请求会生成以下形式的 JSON 响应：

数据层

dataLayers 端点可提供指定位置周围区域的详细太阳能信息。该端点会返回 17 个可下载的 TIFF 文件，其中包括数字表面模型 (DSM)、RGB 复合图层（航空影像）和用于标识分析边界的遮罩图层等。

以下示例展示了针对 dataLayers 方法的 REST 请求的网址：

https://solar.googleapis.com/v1/dataLayers:get?parameters

添加请求网址参数，以指定以下内容：

  • 相应位置的纬度和经度坐标
  • 位置周围区域的半径（以米为单位）
  • 结果中允许的最低质量

如需请求实验数据，请设置以下参数：

  • requiredQuality = BASE
  • experiments = EXPANDED_COVERAGE
curl -X GET "https://solar.googleapis.com/v1/dataLayers:get?location.latitude=4.655719&location.longitude=-74.128971&radiusMeters=100&requiredQuality=BASE&experiments=EXPANDED_COVERAGE&key=YOUR_API_KEY"

该请求会生成 JSON 格式的响应，如下所示：
