Data Transfer with the Mobile Data Manager

The Mobile Data Management tool allows map data saved as a Global Mapper Mobile Package file (*.GMMP) to be wirelessly transferred between Global Mapper desktop and Global Mapper Mobile.

Note: To transfer data with this tool, both the mobile device and desktop need to be connected to the same wireless network, and the Configuration option to Enable Device Discovery on the mobile device needs to be turned on.

Mobile Device Data Link

Refresh will refresh the list of files on the mobile device.

Use Get File with a file selected to transfer the selected map from the connected mobile device and open it in Global Mapper.

Use Add File to transfer a Global Mapper Mobile Package file or GeoPackage file to the connected mobile device. You will be prompted to select the file to add after clicking Add File.

Delete File will remove the selected file from the connected mobile device.

Package File Export

The Package File Export tab of the Mobile Data Management dialog sets up the export of data from the Global Mapper desktop workspace to Global Mapper Mobile Package file (*.GMMP). Steps to create a Global Mapper Mobile Package file (*.GMMP) with the Mobile Data Management tool can be found here.

Use the check boxes next to each listed layer to include or exclude them from the package file export.

Add Template Layer

The Add Template Layer button adds a Feature Template layer to the workspace and the package file export. In the resulting dialog enter the layer name for the Template Layer and select the saved template from the drop down. Some vector layer options for the template layer are also available to set up the layer as it is added to the package file for export.

The Edit Templates button opens a Configuration dialog allowing templates to be added to edited.

Add Layer(s) From File...

To add data from a file to the mobile package, use the Add Layer(s) from File button and select the data layer to load. The selected file will be loaded into the workspace and the Package File Export Layers list.

Save As...

To export and save a Global Mapper Mobile Package file (*.GMMP) locally, use the Save As button. A prompt to select the export location and name the file will appear, and then the Global Mapper Mobile Package Export Options dialog opens to complete the export.

A Global Mapper Mobile Package can then be transferred to a mobile device via email, a wired connection, or a shared drive.

Upload to Device

To upload data directly to a mobile device, the device must be connected to the Mobile Data Management tool via the Mobile Device Data Link tab.

The selected data layers can be exported to Global Mapper Mobile Package format and uploaded to the device with the option to save a copy of the generated *.gmmp file locally.

Package File Import

Note: This tool requires Global Mapper Pro (desktop)

The Package File Import tab of the Mobile Data Management tool allows you to import and combine data from Global Mapper Mobile Package files (*.gmmp). Combined data from the package files can then be loaded into the open workspace.

In this tool two files will be selected. Items will be merged from the FROM file to the TO file.

Note: Data merging is based on a GMMID value automatically created for layers and features in saved/exported Global Mapper Mobile Packages files. Global Mapper desktop v24.0 and the latest version of Global Mapper Mobile must be used to generate the needed GMMID values for data merging.

Load...

Click the Load button to select the package files to merge data TO and FROM. Use the Browse... button to select package files through Windows File Browser. Once files are selected click OK to view items in differences in package files.

After selecting the Global Mapper Mobile Package Files (*.gmmp) to merge, the Package File Import tab will populate showing the layers and features from both package files.

The Item column indicates the item type (layer type, vector feature type, attribute, etc.). Items are grouped in branches by layer and feature type to mimic how individual features are found in an open map file.

The TO File Value displays the layer name, feature name, or value for all items found in the imported TO file. The FROM File Value displays the layer name, feature name, or value for all items found in the imported FROM file. The TO and FROM values will match if the item exists in both files, and the value [no match] will in the TO or FROM value column if the item does not exist in that file.

Keep / Ignore Differences

A folder icon indicates an feature group, a folder icon with a question mark indicates an feature group with differences, and a blue question mark indicates an unresolved difference in a layer or single item.

Right-click on a selected item indicated with an icon to choose to Keep TO Item or Keep FROM item. Right-click on an item group to Keep all TO items in branch or Keep all FROM items in branch.

Use the Prev and Next buttons to move through all the discovered differences between the TO and FROM files.

Clicking Keep All will merge in any new items in FROM file (i.e. no matching items in TO file), and will merge in any changed values in FROM file (item exists in both files, but has different value). It will also keep any items in TO file that are not in FROM.

Additional Options

Enable Show Differences Only to filter the displayed items to only show the discovered differences.

Enable Always Load After Merge to load the merged data into the workspace.

Expand All Differences will expand all item groups containing differences.

Collapse All will collapse all item groups.

Merge...

Click Merge to merge and export the package files with the kept differences from the selected file. When prompted enter a new file name for the merged data, and then set the Global Mapper Mobile Package Export Options to complete the export.

View...

Clicking View will open a set of 2D viewers to visualize and compare the loaded TO and FROM data. Select a feature or feature property from the main dialog to select it in the viewer.

Use mouse wheel or buttons to zoom. When you zoom or pan in one viewer, the other will change to match.
