PostGIS supports another kind of spatial data type called a *raster*. Raster data, much like geometry data, uses **Cartesian coordinates** and a spatial reference system. However instead of vector data, raster data is represented as an n-dimensional matrix consisting of pixels and bands. The bands defines the number of matrices you have. Each pixel stores a value corresponding to each band. So a 3-banded raster such as an RGB image, would have 3 values for each pixel corresponding to the Red-Green-Blue bands.
PostGIS は *raster* という、これまでと別の空間データ型を持っています。ラスタデータはジオメトリデータと同じで **直交座標** と空間参照系を使用します。しかし、ラスタデータはベクタデータと違い、ピクセルとバンドで構成される n次元行列 として表されます。バンドは持っている行列の数を定義します。ピクセルはそれぞれが、バンドに対応する値を格納します。RGB画像のような 3バンドラスタ では、ピクセルはおのおの、赤、緑、青のバンドに対応する三つの値を持ちまラスタ形式は一般的に標高データ、気温データ、衛星データ、環境汚染、人口密度、環境危険の発生などを表現する主題データなどを格納するためによく使われます。意味のある座標位置を持つ数値データの格納のためにラスタを使用することができます。ラスタの制限は、特定のバンドの全てのデータについて、数値データタイプが同じでなければならないことだけです。
