Create Surface Model

Résumé

Creates a surface model within the Bathymetric Information System (BIS) workspace.

Utilisation

  • If an existing model name is provided for the BIS Model Name parameter, the existing model will be overwritten if the BIS is stored in a file geodatabase, or a new model version will be created if the BIS is stored in a versioned enterprise geodatabase.

  • The Filter Expression parameter takes a SQL expression as an input. For details on the syntax, how to construct a SQL expression, and to view examples, see Building a query expression or SQL reference for query expressions used in ArcGIS.

  • Once this tool has finished executing, the new surface model will be visible in the Load Surface Model and Manage Surface Model dialog boxes, accessible from the Compose Surface window.

  • The output of this tool can be chained to other bathymetry tools, such as Export Points or Export BIS Metadata.

  • When constructing a filter expression, you can reorder the fields in alphabetical ascending or descending order using the options found by clicking the down arrow in the upper right corner of the Query Builder dialog box.

  • Spatial Filter Geometry and Spatial Filter Method can be used to restrict the datasets added to the surface model on the basis of location rather than metadata.

  • If both a filter expression and a spatial filter are supplied, the resulting surface model will contain the datasets that satisfy both the metadata and location requirement.

  • If no value is specified for Spatial Filter Method, or if the value is left blank, INTERSECT will be applied when the tool executes.

Syntaxe

CreateSurfaceModel(bis_workspace, model_name, {filter_expression}, {filter_geometry}, {filter_method}, {rule_file}, {model_description})
ParamètreExplicationType de données
bis_workspace

The Bathymetric Information System (BIS) containing the datasets and to which the surface model should be saved. This parameter accepts any geodatabase (.gdb) or enterprise database connection file (.sde) that has been registered as a BIS and which is on the latest version.

Workspace
model_name

The name to associate with the surface model being saved. Providing an existing surface model's name will overwrite that model in a file geodatabase BIS or save a new version in a versioned enterprise BIS.

String
filter_expression
(Facultatif)

The SQL expression used to filter datasets in the BIS by their associated metadata.

SQL Expression
filter_geometry
(Facultatif)

The point, line, or polygon geometry that should be used to spatially constrain the datasets saved to the surface model.

Feature Layer
filter_method
(Facultatif)

The spatial relationship to apply to the BIS dataset using the specified filter geometry.

  • INTERSECT —Selects all BIS datasets whose rectangular footprints intersect the specified geometry. This is the default.
  • WITHIN —Selects all BIS datasets whose rectangular footprints are fully within the geometry specified in the filter_expression parameter. This only applies to polygon geometry.
  • NOT_INTERSECT —Selects the inverse of INTERSECT.
  • NOT_WITHIN —Selects the inverse of WITHIN. This only applies to polygon geometry.
String
rule_file
(Facultatif)

The rule file that determines the sort order of datasets in the surface model. This is used to deconflict the surface where multiple datasets overlap and can be saved from the Compose Surface window. Leaving this parameter blank will result in the datasets being ordered alphabetically by their dataset name.

File
model_description
(Facultatif)

A short piece of text describing the surface model. This is limited to 255 characters.

String

CreateSurfaceModel example (stand-alone script)

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

# Name: CreateSurfaceModel_Ex1.py
# Description: Creates a surface model comprised of a filtered and ordered list of datasets within a BIS geodatabase
# Requirements: ArcGIS for Maritime Bathymetry

import arcpy
arcpy.CheckOutExtension("Bathymetry")

# set up parameters
bis_workspace = r"C:\Data\BIS.gdb"
model_name = "Golden Gate Seafloor"
filter_expression = "(BISDatasetType = 'Gridded BAG' AND CellSize <= 5) AND NOT ExtSurveyDate <= 01/01/2014"
filter_geometry = r"C:\Data\Areas.gdb\GoldenGate"
filter_method = "INTERSECT"
rule_file = r" C:\Users\BathyAdmin\AppData\Roaming\ESRI\Bathymetry10.4\SavedRules\OrderedBy_Date_Cellsize.rul"
model_description = "Recent, high-resolution bathymetry for the Golden Gate region of the greater San Francisco Bay"

# execute the tool
arcpy.CreateSurfaceModel_bathymetry(bis_workspace, model_name, filter_expression, filter_geometry, filter_method, rule_file, model_description)
