PixelGrid
通过地图投影定义地球表面上的像素网格。如果投影具有标准代码,则系统会设置 crsCode
(非空)。如果投影是非标准投影,则系统会设置 crsWkt
。如果投影后的转换是线性转换,则系统会设置 affineTransform
。

字段 |
dimensions |
object (GridDimensions )
像素网格的尺寸。
|
affineTransform |
object (AffineTransform )
仿射转换。
|
联合字段 crs 。像素网格的坐标参考系,应尽可能指定为标准代码,否则应采用 WKT 格式。crs 只能是下列其中一项: |
crsCode |
string
标准坐标参考系代码(例如“EPSG:4326”)。
|
crsWkt |
string
采用 WKT 格式(“已知文本”)的坐标参考系。
