Method: projects.assets.patch

    Updates an asset. There are a number of constraints on the update operation:

    • Only the title , description , startTime , endTime , and properties fields of the asset can be updated.
    • Naming "properties" in updateMask results in all user-defined properties of the asset being replaced by the properties in asset .
    • Naming "title" , "description" , "startTime" or "endTime" in updateMask and not providing a value in asset results in that field becoming unset.
    • It is possible to update individual properties by naming them in updateMask , like "properties.my_property_name" . The property's value will be set to the corresponding value from asset.properties . If there is no corresponding value in asset.properties , or if there is a value but it is a NullValue , the property will be deleted from the asset.
    • Properties can be set only to string or number values, or deleted by specifying a NullValue .
    • Supplying an empty updateMask will result in the asset's timestamps and properties all being replaced by the values in asset .

    Fields
    asset.type

    enum ( Type )

    The type of the asset.

    asset.id

    string

    The ID of the asset. Equivalent to name without the "projects/*/assets/" prefix (e.g. "users/ / "). Note that this is intended for display purposes only. It should not be used as an input to another operation. Use name instead.

    asset.updateTime

    string ( Timestamp format)

    The last-modified time of the asset.

    Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    asset.title
    (deprecated)

    string

    The title of the asset.

    asset.description
    (deprecated)

    string

    The description of the asset.

    asset.properties

    object ( Struct format)

    Key/value properties associated with the asset.

    asset.startTime

    string ( Timestamp format)

    The timestamp associated with the asset, if any, e.g. the time at which a satellite image was taken. For assets that correspond to an interval of time, such as average values over a month or year, this timestamp corresponds to the start of that interval.

    Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    asset.endTime

    string ( Timestamp format)

    For assets that correspond to an interval of time, such as average values over a month or year, this timestamp corresponds to the end of that interval (exclusive).

    Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .

    asset.geometry

    object ( Struct format)

    The spatial footprint associated with the asset, if any, as a GeoJSON geometry object (see RFC 7946).

    The number of features in the asset, if applicable.

    asset.quota

    The quota information associated with the folder asset, if any. Returned for top-level user-owned folder assets (e.g. "users/*" or "projects/*").

    asset.tilesets[]

    object ( Tileset )

    The tilesets backing this image. Only present for external images, whose pixels are retrieved from storage not owned by Earth Engine.

    updateMask

    string ( FieldMask format)

    The update mask specifying which fields of the asset to update.

    This is a comma-separated list of fully qualified names of fields. Example: "user.displayName,photo" .
