Thank You for Your Support of Planetary Pro - Version beta 0.2.1 Now Available!

What's New:

  1. We've added Full Image download capability in Export Imagery, considering some users' needs for complete imagery. Users can now choose to download either cropped images (Crop Image) or full scenes (Full Image) based on their requirements.

  2. We've received feedback about statistical analysis issues when input regions greatly exceed image boundaries. We've made two key improvements: first, implementing topological calculations for user-defined regions (supported by the polybool library), and second, introducing an alternative data access method for full image analysis.

  3. In response to users requesting more detailed data information, we've implemented an interface for viewing image attributes, providing more comprehensive access to the data's properties.

  4. We've enhanced the region filtering functionality by adding support for Shapefile (.shp) format, enabling viewing and selection of multiple features within files. The manual input mode now supports both Degree and DMS formats, with the ability to switch between them.

  5. We've temporarily disabled the Select All function for band selection. We encourage users to carefully choose bands based on their specific needs - following the principle that "less is more" - which also helps reduce the server processing load.

Q&A

How does the full image download work?
We utilize Microsoft Planetary Computer's STAC API with SAS token authentication, then redirect the download links to your browser. This approach gives users more flexibility in managing their downloads.

感谢大家对 Planetary Pro 的关注和使用。现在 Planetary Pro 推出 beta 0.2.1 版本，欢迎大家继续关注啦~

更新说明：

  1. 支持整幅影像下载：考虑到部分用户有下载整幅影像的需求，我们在 Export Imagery 中新增了 Full Image 的下载功能。用户可以根据需求下载裁剪的影像（Crop Image）和整幅影像（Full Image）。
  2. 支持整幅影像统计：我们收到用户在统计功能使用时遇到的问题，集中在输入的区域远大于影像范围时报错。我们做了两部分内容的改进：一是对用户输入的区域信息进行拓扑运算（由 polybool 第三方库提供支持），二是整幅影像采用另外的数据访问方式。
  3. 支持影像信息预览：部分用户对数据条目有更多的信息需求，我们提供了对应影像的属性信息查看接口，对数据返回的属性进行更多披露。
  4. 筛选区域功能改进：新增支持 shp 格式的文件输入，对含有多个要素的文件支持查看和选择；手动输入模式支持 Degree 模式和 DMS 模式，并支持模式切换；
  5. 波段选择功能优化：我们暂时锁定 Select All 的功能键，希望用户在波段选择的时候能够根据实际情况进行筛选，“少即是多”，同时也减轻服务器数据处理负担。

Q&A

下载整幅影像是怎么实现的呢？
我们使用 Microsoft Planetary Computer 的 STAC API，配合 SAS 签名的功能，然后将下载链接转发到浏览器进行下载。此方法能让用户拥有更多的选择余地。
