{
  "name": string,
  "properties": {
    object
  },
  "uriPrefix": string,
  "sources": [
    {
      object (TableSource)
    }
  ],
  "startTime": string,
  "endTime": string
}
Fields
name

string

The name of the asset to be created. name is of the format "projects/*/assets/**" (e.g. "projects/earthengine-legacy/assets/users//"). All user-owned assets are under the project "earthengine-legacy" (e.g. "projects/earthengine-legacy/assets/users/foo/bar"). All other assets are under the project "earthengine-public" (e.g. "projects/earthengine-public/assets/LANDSAT").

properties

object (Struct format)

Additional properties of the asset. The property names "system:time_start" and "system:time_end" are deprecated. Use the fields startTime and endTime instead.

uriPrefix

string

The optional prefix prepended to all uris defined in this manifest.

sources[]

object (TableSource)

The sources which comprise this table.

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.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

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).

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

TableSource

A table file.

  "dateFormat": string,

  "csvQualifier": string
}
Fields
uris[]

string

The URIs of the data to import. Currently only Google Cloud Storage URIs are supported. Each URI must be specified in the following format: "gs://bucket-id/object-id". The primary object should be the first element of the list, sidecar files are inferred from the filepath of the primary object. Only one URI is currently supported. If more than one URI is specified an INALID_ARGUMENT error is returned.

charset

string

The name of the default charset to use for decoding strings. If empty, the charset "utf-8" is assumed by default.

maxErrorMeters

number

The max allowed error in meters when transforming geometry between coordinate systems. If empty, the max error is 1 meter by default.

maxVertices

integer

The max number of vertices. If not zero, geometry will be subdivided into spatially disjoint pieces which are each under this limit.

crs

string

The default CRS code or WKT string specifying the coordinate reference system of any geometry that does not have one specified. If left blank, the default will be EPSG:4326: https://epsg.io/4326. For CSV/TFRecord sources only.

geodesic

boolean

The default strategy for interpreting edges in geometry that do not have one otherwise specified. If false, edges are straight in the projection. If true, edges are curved to follow the shortest path on the surface of the Earth. When blank, defaults to false if 'crs' is a projected coordinate system. For CSV/TFRecord sources only.

primaryGeometryColumn

string

The geometry column to use as a row's primary geometry when there is more than one geometry column.

If left blank and more than one geometry column exists, the first geometry column encountered is used. For CSV/TFRecord sources only.

xColumn

string

The name of the numeric x coordinate column for deducing point geometry. If the yColumn is also specified, and both columns contain number values, then a point geometry column will be constructed with x,y values in the coordinate system given in 'crs'. If left blank and 'crs' does not specify a projected coordinate system, defaults to "longitude". If left blank and 'crs' does specify a projected coordinate system, defaults to "" and no point geometry is generated.

A generated point geometry column will be named {xColumn}_{yColumn}_N where N is appended such that {xColumn}_{yColumn}_N is unique if a column named {xColumn}_{yColumn} already exists. For CSV/TFRecord sources only.

yColumn

string

The name of the numeric y coordinate column for deducing point geometry. If the xColumn is also specified, and both columns contain number values, then a point geometry column will be constructed with x,y values in the coordinate system given in 'crs'. If left blank and 'crs' does not specify a projected coordinate system, defaults to "latitude". If left blank and 'crs' does specify a projected coordinate system, defaults to "" and no point geometry is generated.

A generated point geometry column will be named {xColumn}_{yColumn}_N where N is appended such that {xColumn}_{yColumn}_N is unique if a column named {xColumn}_{yColumn} already exists. For CSV/TFRecord sources only.

dateFormat

string

A format with which to parse fields encoding dates. The format pattern must be as described at

http: //joda-time.sourceforge.net/apidocs/org/ // joda/time/format/DateTimeFormat.html. If left blank, dates will be imported as strings. For CSV/TFRecord sources only.

csvDelimiter

string

When ingesting CSV files, a single character used as a delimiter between column values in a row. If left blank, defaults to ','. For CSV sources only.

csvQualifier

string

When ingesting CSV files, a character that surrounds column values (a.k.a. "quote character"). If left blank, defaults to '"'. For CSV sources only.

If a column value is not surrounded by qualifiers, leading and tailing whitespace is trimmed. For example: ..., test,... <== this value is not qualified becomes the string value: "test" <== whitespace is stripped

where: ...," test",... <== this value IS qualified with quotes becomes the string value: " test" <== whitespace remains!
