PixelGrid
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
透過地圖投影，定義地球表面的像素格線。如果投影有標準代碼，則會設定 crsCode (非空白)。如果投影方式是非標準投影方式，則會設定 crsWkt。如果後投影轉換為仿射，則會設定 affineTransform。

} |
| 欄位 |
dimensions |
object (GridDimensions)
像素格線的尺寸。
|
affineTransform |
object (AffineTransform)
仿射變換。
|
聯集欄位 crs。像素格線的座標參考系統，請盡可能指定為標準代碼，否則請使用 WKT 格式。crs 只能是下列其中一項： |
crsCode |
string
標準座標參考系統代碼 (例如「EPSG:4326」)。
|
crsWkt |
string
WKT 格式 (「Well-Known Text」) 的座標參考系統。
