我正在尝试上传一些大的几何图形到谷歌地球引擎。
以下是?sf_as_ee描述中给出的示例代码:
# # 3. Upload large geometries to EE asset
# ee_Initialize(gcs = TRUE)
# assetId <- sprintf("%s/%s", ee_get_assethome(), 'toy_poly_gcs')
# eex <- sf_as_ee(
# x = toy_poly,
# overwrite = TRUE,
# assetId = assetId,
# bucket = 'rgee_dev',
# monitoring = FALSE,
# via = 'gcs_to_asset'
# )我只需要知道如何设置bucket
发自描述:
存储桶字符。要保存中间文件的存储桶(GCS)名称(如果未将via定义为“gcs_to_asset”,则忽略此项)。
我认为它是用于保存中间文件的本地空间,但我无法让它与我通常用于临时文件的文件夹(bucket = 'tempfiles')一起使用。
它在我的工作目录中,但是抛出了这个错误:
Error in value[[3L]](cond) : The data bucket was not found.供参考的文件结构:(在MacOS上)
-R项目(工作目录)
--脚本
-脚本
--临时文件
我也试着将其设置为google驱动器文件夹名称,以为它可能会要求这样做,但也不起作用。任何帮助都将不胜感激!
谢谢!

sf_as_ee(...,via = "gcs_to_asset")是一个两步函数。首先,将几何图形上传到Google Cloud Storage ( GCS ),然后使用manifests upload从GCS迁移到Earth Engine。
要使用sf_as_ee(...,via =“gcs_to_asset”),必须使用保存一个具有读/写service account key资源权限的文件。不能通过 Drive上传文件。
library(rgee)
library(googleCloudStorageR)
ee_Initialize("csaybar", gcs = TRUE)
#> ── rgee 1.0.7 ─────────────────────────────────────── earthengine-api 0.1.245 ──

#> Unable to find a service account key (SAK) file in: /home/csaybar/.config/earthengine//csaybar

#> > https://cloud.google.com/iam/docs/creating-managing-service-account-keys
#> > https://console.cloud.google.com/apis/credentials/serviceaccountkey
#> Until you do not save a SKA file, the following functions will not work:
#> - rgee::ee_gcs_to_local()
#> - ee_as_raster(..., via = "gcs")
#> - ee_as_stars(..., via = "gcs")
#> - ee_as_sf(..., via = "gcs")
#> - sf_as_ee(..., via = "gcs_to_asset")
#> - gcs_to_ee_image
#> - raster_as_ee
#> - local_to_gcs
#> - stars_as_ee此guide说明了如何生成SAK,然后,您需要将其保存到:
rgee::ee_get_earthengine_path()
#> [1] "/home/csaybar/.config/earthengine//csaybar/"出现此特定错误(Error in value[[3L]](cond): The data bucket was not found.)是因为googleCloudStorageR无法识别您的SAK (因此无法识别您的GCS存储桶名称)。
