The Layer Menu contains options for data creation or editing using the selected layers in the Control Center. Many of these options were previously found in the Control Center right-click context menu, and are still available in the Control Center right-click context menu under the Layer sub-menu.

These functions will apply to selected layers, so it is necessary to select the appropriate layers in the Control Center first.

Create Workspace File from Selected Layer(s)

This option will generate a workspace of user-selected layers and settings. This workspace can later be loaded with the Load Workspace option in the File menu.

Export Layer(s) to New File

This option will bring up a dialog to specify the export format. All selected layers in the Control Center that are compatible with the export format will be included.

Add Selected Layer(s) to Map Catalog

Adds the selected layer(s) to an existing Map Catalog.See Add Selected Layers to Map Catalog for more information.

Join Attribute Table/ File to Layer

This allows you to join a table of attribute values, either from a DBF file or from a text file, to the attribute table of a selected layer based on a common value of some attribute. You will be prompted to select the attribute from the attribute table file to join against a user-selected attribute from the selected layers. For text files, the first line must contain the attribute/ column names. Whenever a match is found, the other attributes from the data table are added to the matching record(s) in the file.

Split Into Separate Layers Based on Attribute Value

This option allows you to create new layers by splitting the selected layer(s) into new layers based on a particular attribute value or by the description, type, or name of each feature. The new layers will be grouped together using the name of the original layer unless the original layer was already in a group. This function is also available in the right click layer menu from the Control Center.

Create Area Features from Equal Values

When a single raster or elevation grid layer is selected (with the exception of online sources), this option appears and allows you to create area features covering each distinct color or elevation value encountered in the raster file.

Terrain / Point Cloud Layer Functions

Create Point Cloud from Elevation Layer

This causes a new layer to be created for each selected elevation grid layer with a spot elevation point feature at each grid cell center location. This provides a handy way to edit elevation layers as you can edit the elevation attribute of the created points or remove bad points, then create a new elevation grid from the layer. Point clouds created with this tool are compatible with Global Mapper’s Lidar toolset.

Find Extreme (Min/Max) Elevation Values

This scans the selected elevation grid layers to find the minimum and maximum elevation values and reports both the values and their locations to the user. The complete list (up to 10,000 shared location) will be saved to a file, and a shorter list presented to the user. If enabled the check box to Create Point Features at Extreme Locations found below the reported minimum and maximum elevation locations will prompt the creation of a new layer in the workspace.

For streamed online layers, the data will be sampled at the default zoom level. For further detail in this analysis export the online terrain layer to a local file.

Sort Lidar Point Clouds by 2D location

Reorder the points in the file organization so that they are ordered sequentially by location for faster display and analysis. This speeds up the display and processing of point cloud data. This option is also available in the Lidar Load menu that appears when first loading a point cloud into Global Mapper.

3D Model (Mesh)

Create Mesh Features from Raster/Terrain

This option will create an image draped (if specified) 3D model using the terrain layer and image layer. For more information see Convert a 3D Model / Mesh

Create 3D Areas from 3D Models...

This tool will convert a 3D model into 3D area features, assigned to the TIN Face Area feature type. For more information see Convert a 3D Model / Mesh

Create Image Layer from 3D Model(s)...

For 3D models that contain a texture, this tool will convert the applied texture into an orthoimage. For more information see Convert a 3D Model / Mesh

Create Point Cloud from 3D Model(s)...

This option will convert a 3D model into a point cloud by including the vertices, and sampling the faces. For more information see Convert a 3D Model / Mesh
