How to find and replace data sources in ArcPy?

How to find and replace data sources in ArcPy?

A data source for a layer or table is the combination of the workspace and dataset. The findAndReplaceWorkspacePaths method on the MapDocument object is intended to perform a global find and replace of workspace paths for all layers and tables in a map document that share that workspace path.

How to change workspace type in arcpy.mapping?

The replaceDataSource method on the TableView object is similar to the findAndReplaceWorkspacePath method, but in addition to being able to change a workspace type, the dataset can also be changed. This is the only method that enables you to replace a table’s dataset within a workspace.

What is the find and replace method in ArcGIS?

The findAndReplaceWorkspacePath method on the Layer object is intended to perform a find and replace of the workspace path for a single layer in a map document or a layer file.

When to use an empty string in arcpy.mapping?

If an empty string ( “”) is used for the old_workspace_path parameter and “NONE” is used for the old_workspace_type parameter, all data sources are matched to the new workspace. This allows you to redirect multiple workspaces to a single workspace using a single method. Only an empty string can be used with the keyword NONE.

How to make a feature class unique in ArcPy?

If the name already exists in the output geodatabase, a number will be appended to the end to make the feature class name unique (for example, rivers_1). You can also control the name of the input feature class manually.

What do you need to know about arcpy.mapping?

The SDE connection file information used in the script must be identical to the SDE connection that was used to add data to a map document or layer file. For example, you can have two identical SDE connection files in two separate locations.

What is the Binning method in ArcGIS Pro?

The binning approach provides a Cell Assignment Method for determining each output cell using the points that fall within its extent, along with a Void Fill Method to determine the value of cells that do not contain any LAS points. AVERAGE —Assigns the average value of all points in the cell.

How does the describe function work in ArcPy?

Happily, we can use the arcpy.Describe function to retrieve the suffix-less name for the input dataset, and then use this to create our new output name. The Describe function works for all the types of data that can be used in ArcMap, so this line of our script can cope with (almost) anything we fire at it.

How to define workspaces for Geodatabases in ArcPy?

With file-based geodatabases, it includes the name of the geodatabase. SDE workspace paths are defined by the system path to the SDE connection file. A workspace type is an ArcGIS supported data model format. For example, shapefile, personal geodatabase, file geodatabase, CAD, SDE, and so on.

Can a shapefile be redirected to a geodatabase workspace?

For example, a shapefile called Highways.shp can be redirected to a file geodatabase workspace only if the dataset name in the file geodatabase is also called Highways. Use the replaceDataSource method on the Layer or TableView objects if the dataset name is different.

Where can I find the layer object in ArcGIS?

It can either reference layers in a map document ( .mxd) or layers in a layer ( .lyr) file. The Layer object is essential for managing layers that reside within a map document ( .mxd) or within a layer ( .lyr) file.

How does the updatelayer function work in ArcGIS?

The UpdateLayer function allows you to replace all layer properties available in the ArcMap Layer Properties dialog box using a layer ( .lyr) file that contains the customizations. Group layers and other sublayers (for example, annotation classes) are treated just like ordinary layers.

How to find and replace workspace paths in ArcGIS?

The findAndReplaceWorkspacePaths method on the MapDocument object is intended to perform a global find and replace of workspace paths for all layers and tables in a map document that share that workspace path. This method can be used to replace the path to multiple workspace types at once (for example, CAD files, shapefiles, and file geodatabases).

Do you need the import ArcPy statement in ArcPy?

Since we are going to to write a stand-alone script, the “import ArcPy” statement is needed to import the ArcPy site package, including all its modules and functions. When referencing data on disk, you can limit the need to write the full path by setting the workspace as part of the environment properties.

Are there properties not exposed to ArcPy scripting environment?

Not all layer properties are accessible through the Layer object. There are many properties available in the ArcMap Layer Properties dialog box that are not exposed to the arcpy scripting environment (for example, display properties, field aliases, selection symbology, and so on).

What is replacedatasource method in ArcGIS help?

The replaceDataSource method allows you to change a layer’s workspace and source dataset. For a more detailed discussion, parameter information, scenarios, and code samples, please refer to the Updating and fixing data sources with arcpy.mapping help topic. Depending on the symbology type, a layer’s symbology can be modified.

How to iterate through a list in ArcPy?

I have the portion of code that iterates through these items and is the source of my issue below: arcpy.env.workspace = inputGDB dataset_list= arcpy.ListDatasets () for dataset in dataset_list: featureclass_list=arcpy.ListFeatureClasses (“”,””,dataset) for feature in featureclass_list: inpath=arcpy.Describe (feature).catalogPath

How to get the parameter of a file in ArcPy?

I am then using the standard arcpy.GetParameterAsText (0) code to get the parameter into my Python script. This works fine when I select a file by browsing through the filesystem, as the text in the dialog is the full path to the file, but when I just select from the dropdown list the text I get back is just the filename (eg. file.tif ).

Is it possible to automate changes in arcpy.mp?

Methods are available with the arcpy.mp scripting environment that make it possible to automate these changes without having to open a project. You have control of updating data sources for individual layers or tables, or you can update all the layers or tables in a common workspace at once.

How to change data source in ArcGIS Pro?

This script changes the data source of a relate on a layer. The script changes the dataset and the file geodatabase of the relate. This script changes the data source of a layer where the feature dataset names are different between the existing and new geodatabase. Updating the feature dataset requires modifying the CIM.

How are workspace paths defined in arcpy.mapping?

A workspace path is the system path to the workspace. In the case of file-based data (for example, CAD, shapefiles, rasters), it includes the name of the folder that contains the data. With file-based geodatabases, it includes the name of the geodatabase. SDE workspace paths are defined by the system path to the SDE connection file.

Which is an example of a workspace type in ArcGIS?

A workspace type is an ArcGIS supported data model format. For example, shapefile, personal geodatabase, file geodatabase, CAD, SDE, and so on. A dataset is the feature class or table that is in a workspace. When a dataset name is required, it is the name of the object in the workspace, not the way it appears in a map document’s table of contents.

How to change workspace path in arcpy.mapping?

See the Common Scenarios section below. replaceWorkspaces or replaceDataSource allows you to change the workspace path, workspace type, and / or change the dataset name. The capabilities of these methods overlap; therefore, there are multiple ways of updating a layer or table’s workspace or dataset.

Which is an example of an ArcGIS workspace?

A workspace type is an ArcGIS supported data model format. For example, shapefile, personal geodatabase, file geodatabase, CAD, SDE, and so on. A dataset is the feature class or table that is in a workspace.

How to change the feature dataset in ArcGIS Pro?

To change the feature dataset that a layer’s feature class resides in, see the Updating data sources via the CIM section below. Here are several examples of using the updateConnectionProperties function:

Why do data sources need to be repaired?

There are numerous reasons why data sources need to be repaired or redirected to different locations. The idea of making these changes manually in every affected map document can be overwhelming.

What happens if a new data source is not valid?

If validate is True and the new data source exists and is valid, the original data source will be updated to the new data source; otherwise, it will remain pointing to the original data source and nothing will be updated. If validate is False, the new data source does not have to be valid, that is, it might not already exist.

How to search and replace in a shell script?

You can use sed to perform search/replace. I usually do this from a bash shell script, and move the original file containing values to be substituted to a new name, and run sed writing the output to my original file name like this: #!/bin/bash mv myfile.txt myfile.txt.in sed -e ‘s/PatternToBeReplaced/Replacement/g’ myfile.txt.in > myfile.txt.

How to find and replace a string in text file?

Place repl.bat in the same folder as the batch file or in a folder that is on the path. Repl.bat is a hybrid batch file using native Windows scripting and is far faster than a regular batch script. The L switch makes the text search and replace a literal string and I’d expect the 12 MB file to complete in several seconds on a modern PC.

When to use sed for search and replace?

When I install a service I would like to be able to search out a variable in a config file and then replace/insert my own settings in that value. You can use sed to perform search/replace.

How to change the data source path in ArcGIS?

For example, change the data source path from a personal geodatabase to a file geodatabase. You will need to make sure that the dataset exists in the new data location; otherwise, the layer’s data link might be broken. The tool will not override the .mxd file. Instead, a copy of the original file is created by default.

How to find workspace path for SDE connections?

The workspace path for SDE connections is the path to the SDE connection (.sde) file. You can provide the full path to the file, or in the case where the connection file appears in the Database Connections folder, you can use that string in the path as well, for example, find_workspace_path=r”Database Connections\\myConnectionFile.sde”

How to create a raster catalog in ArcSDE?

When creating a raster catalog in an ArcSDE geodatabase, the raster dataset name cannot have spaces. Use underscores to separate words in raster dataset names. The geodatabase to contain the raster catalog. This can be any type of geodatabase: personal, file, or ArcSDE.

Where are the raster datasets stored in ArcGIS?

Raster catalogs can be managed or unmanaged by the geodatabase. When the raster catalog is managed by the geodatabase, then the raster datasets inside the raster catalog will be physically stored within the geodatabase. When a row or raster is deleted from the catalog, it is deleted from the geodatabase.

How to replace a workspace path in ArcGIS?

The findAndReplaceWorkspacePath method is intended for replacing part or all of a layer’s workspace path. The replaceDataSource method allows you to change a layer’s workspace and source dataset.
