Export Points

描述

Exports point features from a point surface model created in the Compose Surface window in ArcGIS Bathymetry.

Exported point features are copied directly from source point datasets associated with representative rasters referenced in the surface model and are not extracted from cell values of the rasters themselves. Footprint polygons specified when point datasets are added to a Bathymetric Information System (BIS) are used to determine the areas in which points should be exported from each source point dataset. In areas of overlap between two or more datasets in the surface model, points from only the topmost dataset (based on ordering rules defined in the surface model) are exported.

使用方法

• The BIS Model parameter is the name of a point surface model contained in the BIS workspace. You create and save BIS models in the Compose Surface window in Bathymetry Solution.

  注：

  • If the surface model you selected in the BIS Model parameter references datasets that were removed from the BIS, the surface model will need to be updated (manually loaded and resaved in the Compose Surface window) before it can be used with this tool.
  • Raster surface models cannot be used with this tool.

• The Output Features parameter is the location where the new output feature class will be generated.

语法

arcpy.bathymetry.ExportPoints(bis_workspace, bis_model, out_features, {exported_fields})

参数	说明	数据类型
bis_workspace	The Bathymetric Information System (BIS) containing the point surface model that should be exported. This parameter accepts any geodatabase (.gdb) or enterprise database connection file (.sde) that has been registered as a BIS and is on the latest version.	Workspace
bis_model	The name of the composite surface in the BIS workspace.	String
out_features	The feature class that will contain the extracted features. This tool will output a new z-enabled point feature class.	Feature Class
exported_fields （可选）	Specifies the fields to be included in the output feature class. INCLUDE_ALL_FIELDS —All fields from the input point feature class will be included in the output feature class. INCLUDE_GEOMETRY_ONLY —Only point geometries will be included in the output feature class. This is the default.	Boolean

代码示例

ExportPoints example (stand-alone script)

The following stand-alone script demonstrates how to use the ExportPoints tool.

# Name: ExportPoints_Example.py
# Description: Extracts point features from a BIS composite surface. 
# Requirements: ArcGIS Bathymetry

# setup parameters
bis_workspace = "C:/data/BIS.gdb"
bis_model = "NewModel"
out_features = "C:/output/Output.gdb/PointFC"
exported_fields = "INCLUDE_GEOMETRY_ONLY"

# for a stand-alone script, check out the extension first
arcpy.CheckOutExtension("Bathymetry")

# execute the tool
arcpy.ExportPoints_bathymetry(bis_workspace, bis_model, out_features, exported_fields)
