Access public data (original) (raw)

Some data stored in Cloud Storage is configured so that it's readable by anyone at any time. This public data can be accessed in several ways, depending on how you want to work with the data.

API Link

Get the name of the public object and the bucket that stores the object.
Use the following URI to access an object in the bucket:
https://storage.googleapis.com/BUCKET_NAME/OBJECT_NAME

For example, the Google public bucket gcp-public-data-landsat contains the Landsat public dataset. You can link to the publicly shared objectLC08/01/001/003/LC08_L1GT_001003_20140812_20170420_01_T2/LC08_L1GT_001003_20140812_20170420_01_T2_B3.TIFwith the link:

https://storage.googleapis.com/gcp-public-data-landsat/LC08/01/001/003/LC08_L1GT_001003_20140812_20170420_01_T2/LC08_L1GT_001003_20140812_20170420_01_T2_B3.TIF

Console

Get the name of the public object and the bucket that stores the object.
Using a web browser, access the object with the following URI (you are asked to sign in if you are not already signed in):
https://console.cloud.google.com/storage/browser/_details/BUCKET_NAME/OBJECT_NAME
If the public has permission to list the bucket's contents, you can list all the objects in the bucket with the following URI:
https://console.cloud.google.com/storage/browser/BUCKET_NAME

For example, the Google public bucket gcp-public-data-landsat contains the Landsat public dataset. You can access the bucket with:

https://console.cloud.google.com/storage/browser/gcp-public-data-landsat

Command line

If you don't have the gcloud CLI,follow these instructions to install it.
- When installing the gcloud CLI, if you don't want to authenticate, skip the step of running the command gcloud init, and instead run the following command:
  gcloud config set auth/disable_credentials True
Get the name of the public object and the bucket that stores the object.
If permission to list the bucket's contents is granted to the public, you can list some or all of the objects contained in the bucket by using the ls command.
For example, the Google public bucket gcp-public-data-landsat contains the Landsat public dataset. You can list objects with the prefixLC08/01/001/003/LC with the following command:
gcloud storage ls --recursive gs://gcp-public-data-landsat/LC08/01/001/003/LC*
Download specific public objects contained in the bucket by using thecp command.
For example, the following command downloads a file from the bucketgcp-public-data-landsat to your local directory:
gcloud storage cp gs://gcp-public-data-landsat/LC08/01/001/003/LC08_L1GT_001003_20140812_20170420_01_T2/LC08_L1GT_001003_20140812_20170420_01_T2_B3.TIF .
