Python ArcGIS RasterCollection.filter_by_geometry用法及代码示例

本文简要介绍 python 语言中 arcgis.raster.RasterCollection.filter_by_geometry 的用法。

用法:

filter_by_geometry(query_geometry_or_extent, context=None)

返回：

仅包含满足过滤器的项目的 RasterCollection 对象

filter_by_geometry 方法过滤 RasterCollection，以便仅返回与几何图形相交的栅格。

Parameter	Description
query_geometry_or_extent	过滤项目的必需对象，以便仅返回与对象相交的项目。这可以通过几何对象、光栅对象、ImageryLayer 对象来指定。
context	可选字典。用于控制 RasterCollection 创建的其他属性。上下文参数的默认值将与应用于父集合的上下文设置的默认值相同。 目前可用： query_boundary: This boolean value set to this option determines whether to add SHAPE field to the RasterCollection. The value in the SHAPE field represents the boundary/geometry of the raster. The query_boundary parameter is honoured only when the RasterCollection is created from a list of Rasters. True: Set query_boundary to True to add the SHAPE field to the RasterCollection. False: Set query_boundary to False to not add the SHAPE field to the RasterCollection. (Creation of RasterCollection would be faster) Example: {“query_boundary”:True}

例子：

# Usage Example: Filters the raster collection based on specified geometry.

aoi = {
        "spatialReference": {"wkid": 32610},
        "xmax": 725000,
        "xmin": 720000,
        "ymax": 4300000,
        "ymin": 4250000
      }

aoi_geometry = Geometry(aoi)

filtered_rc_geom = rc.filter_by_geometry(query_geometry_or_extent=aoi_geometry)
