サマリー
The ArcGISProject object provides access to ArcGIS Pro project methods and properties. A reference to this object is essential for most map automation workflows.
説明
The ArcGISProject object is usually one of the first object references created in a map automation script because it is the main entry point to access most other objects in ArcGIS Pro. A project is referenced using the ArcGISProject function. Its properties allow you to get or set project settings such as defaultGeodatabase, defaultToolbox, documentVersion, filePath, and others. Its methods allow you to manage project items such as updateFolderConnections, updateDatabases, createMap, and createLayout, and copy or delete some project items using the copyItem or deleteItem methods, respectively.
The updateConnectionProperties method is useful for replacing data sources in a project. Data sources can be replaced on the ArcGISProject, Map, Layer, or Table object. See the Updating and fixing data sources help topic for more detailed information and code samples.
The importDocument method allows you to import map (.mxd), globe (.3dd), and scene (.sxd) documents into a project. This provides a mechanism for automating the conversion of these document types into the ArcGIS Pro project. The importDocument method also allows you to import map files (.mapx), layout files (.pagx), and report files (.rptx) into an existing project.
Once you have a reference to an ArcGISProject object, you can access other objects using a number of list functions. For example, you can access a Map object using the listMaps method or a Layout object and a Report object using the listLayouts and listReports methods, respectively.
The following diagram illustrates, along the left side, the use of list functions for navigating and referencing the objects in a project. The diagram is only an example and does not display a complete set of objects and list methods.
The diagram above, along the right side, also illustrates many of the create functions. For example, you can use createMap to create a Map object, createLayout to create a Layout object, or createReport to create a Report object.
注意:
The createGraphicElement, createGroupElement, createPictureElement, and createTextElement methods are also available on the ArcGISProject object because they allow you to create the elements in either a Layout object or a graphics layer in a Map object.
ヒント:
When creating elements in a graphics layer in a map, graphic layers are limited to a set number of features and overall size. See Work with graphics layers for more information.
There are a few methods and properties that only work with scripts that are run in the application such as scripts run in the Python window, a notebook, or those associated with a script tool. These are activeMap and activeView properties and the closeViews() method. The activeMap property will return the Map object associated with either an active map view or the active map frame on an active layout view. If these conditions are not met, NoneType will be returned. The activeView property will return either a MapView object if a map view is active or a Layout object if a layout view is active. If no views are active, both properties will return None. These properties will always return None when a script is run outside the application, because views are only relevant when the application is open. The MapView object returned from the activeView property is the only way to change the extent associated with a map view. There are multiple functions available on the MapView class that allow you to change the extent, such as camera, panToExtent, ZoomToAllLayers, and ZoomToBookmarks. The closeViews function is useful for closing specific view types in the application. To give focus to a specific view, close all views and use the openView method on the Layout, Map, or Report class.
注意:
Projects can be referenced multiple times, but only the first reference can be saved directly because the other references will be opened as read-only. The ArcGISProject object has an isReadOnly property that can be used to determine a project's read state before calling a method such as saveACopy instead of save.
プロパティ
| プロパティ | 説明 | データ タイプ |
| activeMap (読み取り専用) | Returns the map object associated with the focused view within the application. If a layout view is active, it will return the map associated with the active map frame. 注意:This property is designed to be run from within the application using a script tool, the Python window, or a Notebook. If a script is run outside of the application, a value of None will always be returned. | Map |
| activeView (読み取り専用) | Returns a MapView or a Layout, depending on the current view. If the ArcGIS Pro project has no open views, or if the active view is something other than a map view or layout view (for example, a chart, table, Model Builder view, and so on), None will be returned. 注意:This property is designed to be run from within the application using a script tool or the Python window, or a Notebook. If a script is run outside of the application, a value of None will always be returned. | Object |
| databases (読み取り専用) | Returns a list of Python dictionaries, each representing the properties for individual databases in a project. To modify the databases, see the updateDatabases method. | List |
| dateSaved (読み取り専用) | Returns a Python datetime object that reports the project's last saved date. | DateTime |

document_path | A string that includes the system path and name of a document (.mxd, .3dd, or .sxd) or a map file (.mapx), layout file ( .pagx), or report file (.rptx). | String |
include_layout | A Boolean parameter indicating whether the layout from a map document (.mxd) is imported. If set to True, the layout and all data frames are imported. If set to False, only the data frames are imported. This parameter is ignored for other file types. (デフォルト値は次のとおりです True) | Boolean |
reuse_existing_maps | A Boolean parameter to prevent the creation of duplicate maps in the project. If reuse_existing_maps is set to True, it checks the project for the maps referenced in the imported file and only copies maps that don't already exist in the project. There may be cases in which maps have the same name in different imported sources, so you may want to set this value to False. (デフォルト値は次のとおりです False) | Boolean |
log_files | A Boolean parameter that controls if log files are written to the ImportLog folder in the project's homeFolder. Log files can be useful for identifying possible warnings and errors during import but they can also accumulate if not properly managed. (デフォルト値は次のとおりです True) | Boolean |
| データ タイプ | 説明 |
| Object | The type of object returned is based on the file being imported. When importing a map document (.mxd), if include_layout is True, it returns a reference to the layout. If include_layout is False, it returns the first map in the map document. It returns the only single map found in a globe (.3dd) or scene (.sxd) document. The corresponding layout is returned with a .pagx file and report with an .rptx file. |
This method imports one document at a time. To import multiple documents, run the method once for each document. A map document (.mxd) always has a layout. While migrating map documents, if you do not want to import the layout, set include_layout=False.

new_connection_info | A string that represents the workspace path or a Python dictionary that contains connection properties with the new source information. | String |
auto_update_joins_and_relates | If set to True, the updateConnectionProperties method will also update the connections for associated joins or relates. (デフォルト値は次のとおりです True) | Boolean |
validate | If set to True, the connection properties will only be updated if the new_connection_info value is a valid connection. If it is not valid, the connection will not be replaced. If set to False, the method will set all connections to match the new_connection_info value, regardless of a valid match. In this case, if a match does not exist, the data sources would be broken. (デフォルト値は次のとおりです True) | Boolean |
ignore_case | Determines whether searches will be case sensitive. By default, queries are case sensitive. To perform queries that are not case sensitive, set ignore_case to True. (デフォルト値は次のとおりです False) | Boolean |

updateDatabases (databases, {validate})| パラメーター | 説明 | データ タイプ |
databases [databases,...] | A list of Python dictionaries that each contain properties to an individual database. The dictionary keys are defined below.
| List |
validate | If set to True, the database will only be added if the databasePath is a valid database. If it is not valid, the database will not be added and the function will return the dictionary as an invalid database. If set to False, the method will add all the databases to the project, regardless of whether the database can be connected to. (デフォルト値は次のとおりです True) | Boolean |
| データ タイプ | 説明 |
| List | A list of invalid databases. |
To update a project's databases, you must set the entire list of databases at once. You cannot add, remove, or update a single database at a time. You can either build a new list from scratch or you can modify the list returned by the databases property and push the entire list back to the project using the updateDatabases method.
updateFolderConnections (folder_connections, {validate})| パラメーター | 説明 | データ タイプ |
folder_connections [folder_connections,...] | A list of Python dictionaries that each contain connection properties to an individual folder. The dictionary keys are defined below.
| List |
validate | If set to True, the folder will only be added if the connectionString is a valid path. If it is not valid, the folder will not be added and the function will return the dictionary as an invalid folder. If set to False, the method will add all the folders to the project, regardless of whether the folder is valid. (デフォルト値は次のとおりです True) | Boolean |
| データ タイプ | 説明 |
| List | A list of folders that do not have valid connections. |
To update a project's folder connections, you must set the entire list of databases at once. You cannot add, remove, or update a single folder connection at a time. You can either build a new list from scratch or you can modify the list returned by the folderConnections property and push the entire list back to the project using the updateFolderConnections method.
updateStyles (styles)
| パラメーター | 説明 | データ タイプ |
styles [styles,...] | A list of strings that are either a system style keyword such as ArcGIS 2D or the full path to a custom .stylx file. | List |
| データ タイプ | 説明 |
| List | A list of styles that could not be added. Check for spelling or file paths errors. |
To update a project's styles, you must set the entire list of styles at once. You cannot add, remove, or update a single style at a time. You can either build a new list from scratch or you can modify the list returned by the styles property and set the entire list back to the project using the updateStyles method. The Favorites style should not be included in the styles parameter when using the updateStyles method. The Favorites style is always available in a project, as it is linked to your user account. It is not associated with a project and cannot be managed with the updateStyles method. For additional information and code example, refer to the StyleItem class help topic.
The following script appends a system style and a custom style to the current list of styles displayed in the Catalog pane.
p = arcpy.mp.ArcGISProject('current')
s = p.styles
s.append('Pushpins')
s.append(r'C:\Projects\YosemiteNP\Yosemite.stylx')
p.updateStyles(s)updateToolboxes (toolboxes, {validate})| パラメーター | 説明 | データ タイプ |
toolboxes [toolboxes,...] | A list of Python dictionaries that each contain toolbox information. The dictionary keys are defined below.

validate | Specifies whether all toolboxes will be added to the project. If set to True, the toolbox will only be added if the toolboxPath value is a valid path. If it is not valid, the toolbox will not be added and the function will return the dictionary as an invalid toolbox. If set to False, all the toolboxes will be added to the project, regardless of whether the folder is valid. (デフォルト値は次のとおりです True) | Boolean |
| データ タイプ | 説明 |
| List | A list of toolboxes that do not have valid connections. |
To update a project's toolboxes, you must set the entire list of toolboxes at once. You cannot add, remove, or update a toolbox one at a time. You can either build a new list from scratch or you can modify the list returned by the toolboxes property and push the entire list back to the project using the updateToolboxes method.
コードのサンプル
The following script demonstrates how to import documents into an existing ArcGIS Pro template project. It also sets up some of the default project settings and saves the result to a new project file.
import arcpy
#Reference a blank, template project on disk
p = arcpy.mp.ArcGISProject(r"C:\Projects\blank.aprx")
#Import documents set up default GDB and toolbox
p.importDocument(r"C:\Projects\YosemiteNP\Documents\Yosemite.mxd")
p.importDocument(r"C:\Projects\YosemiteNP\Documents\Yosemite_3DViews.3dd")
#Set up default GDB and toolbox
p.defaultGeodatabase = r"C:\Projects\YosemiteNP\Data_Vector\YosemiteData.gdb"
p.defaultToolbox = r"C:\Projects\YosemiteNP\Analysis\AnalysisTools.tbx"
#Save out to a new, different project
p.saveACopy(r"C:\Projects\YosemiteNP\Yosemite.aprx")The following script prints the names of objects in a project . It uses the keyword CURRENT, so it should be run from the Python window. The script prints the name of each map followed by its list of layers. Then it prints the name of each layout along with page size information.
p = arcpy.mp.ArcGISProject('CURRENT')
#Project information
print(f'Project: {p.filePath}')
print(f' Version: {p.filePath}')
print(f' Last saved: {p.dateSaved}')
#Loop through each map
print('Maps and Layers:')
for m in p.listMaps():
print(' Map: ' + m.name)
for lyr in m.listLayers():
print(' Layer: ' + lyr.name)
#Loop through each layout
print('Layouts:')
for lyt in p.listLayouts():
print(f' Name: {lyt.name}')
print(f' W/H: {lyt.pageWidth} x {lyt.pageHeight}')
print(f' Units: {lyt.pageUnits}')The following script uses the keyword CURRENT, so it should be run from the Python window. The script copies an existing map, adds a new layer to it, sets the map's default camera property that controls the extent of newly opened views, exports the map view to PDF, and removes the newly created map from the project.
p = arcpy.mp.ArcGISProject('CURRENT')
#Create a copy of an existing map
existingMap = p.listMaps('Yosemite National Park')[0]
rangerMap = p.copyItem(existingMap, new_name='Ranger Stations')
#Add ranger stations layer file
lyrx = arcpy.mp.LayerFile(r'C:\Projects\YosemiteNP\LayerFiles\Ranger Stations.lyrx')
rangerMap.addLayer(lyrx)
#Close any current layout or map views
p.closeViews('MAPS_AND_LAYOUTS')
#Set the default map camera to the extent of the park boundary before opening the new view
#default camera only affects newly opened views
lyr = rangerMap.listLayers('*Park Boundary')[1]
rangerMap.defaultCamera.setExtent(arcpy.Describe(lyr).extent)
rangerMap.openView()
#export the newly opened active view to PDF, then delete the new map
mv = p.activeView
