Saving Feature Layers

Layer changes can be saved in the following ways:

§  Save Layer Changes to the Original Data Source

§  Save Layer Changes to a New File

§  Export Selected Features to a New File

Saving Layer Changes to the Original Data Source

Modifications to a 3DML feature layer can be made to the original source file.

To save 3DML feature layer changes to the original source file:

1.     In the Project Tree, select the 3DML feature layer.

2.     On the 3D Mesh Layer tab, in the Classification Layer group, click the arrow next to Save Layer, and select Save.

Saving Layer Changes to a New File

You can save a 3DML feature layer to a new local file. This can be particularly useful if a layer is located on a slow accessed remote server; by saving to a local file, you speed up access.

Note:    A layer can be saved to a new file when the Entire Layer was loaded (fully or partially), as well as when a layer was streamed.

You can save to the following file formats:

§  SQLite (.sqlite)

§  GeoPackage (.gpkg)

§  Shapefile (.shp)

§  Geospatial PDF (.pdf)

Note:    Layers saved as Geospatial PDF are read-only when loaded back into TerraExplorer (i.e., their Save command is unavailable).

To save a layer to a new file:

1.     In the Project Tree, select the layer.

2.     On the 3D Mesh Layer tab, in the Classification Layer group, click the arrow next to Save Layer, and select Save as. The Save As dialog is displayed.

3.     Browse to the required Save location and in the File name field, enter the file name.

4.     From the Save as type dropdown list, select a file type (.sqlite, gpkg, .shp, or .pdf).

5.     If you are saving the layer as an .sqlite, .gpkg, or .pdf file, type a Layer name.

6.     Click Save.

Exporting Selected Features to a New File

To export selected features to a new layer:

1.     Select the required features either by selecting them in the 3D Window or by spatial query. See “Selecting Features from the 3D Window” and “Spatial Queries” in this chapter for information.

2.     On the 3D Mesh Layer tab, in the Classification Layer group, click the arrow next to Save Layer and select Save Selected Features As. The Save As dialog is displayed.

3.     Type a File name.

4.     Select a file type (.sqlite, .gpkg, .shp, or .pdf).

5.     If you are saving the layer as an .sqlite, .gpkg, or .pdf file, type a Layer name.

6.     Browse to the required Save location and click Save.
