9 Steps to Linking Workspaces in Global Mapper
What better way to start the new year than by cleaning up your data? Data management can be complicated and whether working alone or with coworkers, organization is key to a smooth workflow.
In the field of GIS, all of the data we manage is inherently location-based so what better way to manage this data than in its geographic context. Global Mapper offers a simple and effective tool for accessing files or data by simply clicking on a link assigned to a specific location on the map. This can be used to display a photograph, a document, a spreadsheet, a pdf, or literally any file that can be opened on your computer. An innovative use of this tool is to create a series of Global Mapper workspaces – Global Mapper’s proprietary map management files – and provide a link to each at the appropriate location on an index map. By clicking on one of these links, all of the appropriate data layers for that project site will be displayed.
In this blog, we’ll walk you through the steps on how to organize your data in a more visually appealing and easy-to-use way. We’ll use an example of a hypothetical transportation agency with several ongoing projects in the state of Maine. The following steps show how to embed links to the associated workspaces into point features in Global Mapper to facilitate data access:
1) Create a map with labeled point features indicating the location of each project site. In this example, there are 14 worksites located across Maine.

2) Prepare each of the corresponding workspace files containing all of the relevant data layers for each site.
3) Select the first point feature with the Digitizer Tool – Here, we chose Site 1.
4) Right-click with the point selected and choose EDIT – Edit Point Feature.
5) In the resulting Modify Feature Info box under Feature Attributes, choose Add File Link(s)…
6) Browse to the previously saved workspace for Site 1 and click the Open button.

7) Click OK to close the Modify Feature Info window. The workspace for Site 1 is now linked to that feature on the index map.
8) Repeat this process for each of the project sites.
9) Save the workspace containing all of the points and their corresponding embedded links.
1) Activate the Feature Info Tool and select the required point feature on the index map.
2) In the resulting Link Attribute Handling dialog box, click the drop-down menu and select either “Open Selected Value as File in Windows (FILE_LINK_1)” or “Open Selected Value as File in Global Mapper (FILE_LINK_1)

3) If opened in Windows, a new instance of Global Mapper will be launched displaying the layers in the linked workspace. If opened in Global Mapper, the linked workspace will replace the index map in the current instance of the software.
