Export.table.toDrive
コレクションでコンテンツを整理
必要に応じて、コンテンツの保存と分類を行います。
FeatureCollection をテーブルとしてドライブにエクスポートするバッチタスクを作成します。タスクは [タスク] タブから開始できます。
用途 | 戻り値 |

Export.table.toDrive(collection, description, folder, fileNamePrefix, fileFormat, selectors, maxVertices, priority) | |
引数 | タイプ | 詳細 |
---|
collection | FeatureCollection | エクスポートするフィーチャー コレクション。 |
description | 文字列、省略可 | 人が読める形式のタスク名。英字、数字、-、_ を使用できます(スペースは使用できません)。デフォルトは「myExportTableTask」です。 |
folder | 文字列、省略可 | エクスポートが保存される Google ドライブ フォルダ。注: (a)フォルダ名が任意のレベルに存在する場合、出力はそのフォルダに書き込まれます。(b)重複するフォルダ名が存在する場合、出力は最後に変更されたフォルダに書き込まれます。(c)フォルダ名が存在しない場合、ルートに新しいフォルダが作成されます。(d)区切り文字を含むフォルダ名(「path/to/file」など)は、システムパスではなくリテラル文字列として解釈されます。デフォルトはドライブのルートです。 |
fileNamePrefix | 文字列、省略可 | ファイル名の接頭辞。英字、数字、-、_ を使用できます(スペースは使用できません)。デフォルトは説明です。 |
fileFormat | 文字列、省略可 | 出力形式: 「CSV」(デフォルト)、「GeoJSON」、「KML」、「KMZ」、「SHP」、「TFRecord」。 |
selectors | List<String>|String(省略可) | エクスポートに含めるプロパティのリスト。カンマ区切りの名前を含む単一の文字列または文字列のリスト。 |
maxVertices | 数値、省略可 | ジオメトリあたりの未カット頂点の最大数。頂点数がこの数を超えるジオメトリは、このサイズより小さいピースにカットされます。 |
priority | 数値、省略可 | プロジェクト内のタスクの優先度。優先度の高いタスクは、より早くスケジュールされます。0 ~ 9999 の整数を指定してください。デフォルトは 100 です。 |
