Can a layer file be saved in ArcGIS Pro?
Layer files saved from ArcGIS Pro cannot be used in ArcMap. In addition to map layers, this tool also accepts layers created by tools such as Make Feature Layer or Make XY Event Layer. If the input layer has a selection applied to it, the output layer file will maintain this selection.
What does the output layer do in ArcGIS?
Determines if the output layer file ( .lyr) will store a relative path to the source data stored on disk, or an absolute path. ABSOLUTE —The output layer file will store an absolute path to the source data stored on disk. This is the default. RELATIVE —The output layer file will store a relative path to the source data stored on disk.
What happens to the output layer file when it is moved?
RELATIVE — The output layer file will store a relative path to the source data stored on disk. If the output layer file is moved, its source path will update to where the source data should be in relation to the new path. The version of the output layer file. CURRENT — The current version.
Layer files can contain one or many layers and those layers can also include group layers. The ArcGIS Pro application can read both .lyr or .lyrx layer file types. Changes can only be saved to a .lyrx layer file type. If you are making changes to a .lyr, you must call the saveACopy method.
How do you add layers to a layer file?
The addLayer method provides a way to add a layer or collection of layers to a layer file. The default add_position adds the layers using the same auto-arrange logic that places layers in a map similarly to how the Add Data button works in the application; it places each layer based on layer weight rules and geometry type.
Where do you place a layer in Python?
BOTTOM — Places the layer or layers at the bottom of the TOC layer stack. TOP — Places the layer or layers at the top of the TOC layer stack. A Python list of Layer objects. The addLayer method provides a way to add a layer or collection of layers to a layer file.
Can a layerfile be saved to.lyrx file?
If a .lyr file type is being referenced and save is called, it will be converted to a .lyrx file type. A string used to save a LayerFile to a new path or file name. You can only save to .lyrx files. Provides an option to save a LayerFile to a different file name.
Can a layer be saved as a layer package?
Saving a layer package. A layer can be saved with its data as a layer package (.lpk). A layer package includes both the layer properties and the dataset referenced by the layer. With a layer package, you can save and share everything about the layer—its symbolization, labeling, field properties, and the data.
When to use save method in ArcGIS Pro?
The save method only works when a variable references a layer file and will not work with a map layer. When a layer is loaded from a layer file it will remember the file name and use that when the save method is called. If a map layer is being referenced, a file name is not initially set, so you will need to use the saveACopy method instead.
