MapInfo Pro provides a way to save your themes and the templates from which you created them.
Saving Thematic Map Layers
To save your thematic maps, on the HOME tab, click Save Workspace. A workspace is a listing of all the tables and settings used in a map. When you open the workspace, MapInfo Pro opens the tables and re-creates the thematic map. If you close a table or Map window without saving your session to a workspace, MapInfo Pro displays the Save Map Objects dialog box and prompts you to do so. The dialog box indicates what types of objects will be lost (for example, thematic layers, label layers) if you do not save your session to a workspace. You can turn off the warning prompt in Map Window preferences on the PRO tab, by clicking Options, and Map Window.
Saving Thematic Templates
Every thematic map begins with a template from which you can then customize for your particular needs. These settings can be saved for future use. In the Create Thematic Map - Step 3 of 3 wizard panel, choose Save As in the Template group box. The Save Theme to a Template dialog box displays. To save your new settings to the existing template, choose OK. To retain both the new and the original template, type a different name into the Name field. To recover any template that ships with MapInfo Pro, copy it from the \THMTMPLT directory on the product DVD. Templates have the extension .THM. In MapInfo Pro files are stored on a per-user basis.
For individual value themes you can also save the actual categories in a theme template. For example, if you choose to build an individual value theme on a table to show land usage, you can assign a different region style to each type of land usage (commercial, forest, residential, farm land etc.). You may then want to take those same assignments and apply them to another table. You can do this by storing the category in a template, it will be associated appropriately when the template is applied to the second table.
To save individual categories in a theme template when creating a new thematic map or for an existing thematic map, from the Modify Thematic Map dialog box choose Save As and specify a template Name. Select the Save Individual Value Categories check box and choose OK. A template is saved that can be used to apply the stored individual categories to a second table. When you choose on the MAP tab, in the Content group, Add Theme. The template's name will appear in the Template Name field of the Create Thematic Map - Step 1 of 3 wizard panel.
Important Notes for Creating and Merging Theme Templates
When you are creating and merging theme templates, MapInfo Pro saves the custom label order only when the option to Save Individual Value categories is selected in the Save Theme to a Template dialog box. This implies that when you create a theme based on a template, MapInfo Pro applies the custom label order only when the thematic expression creates the same categories as those in the template.
When you are merging theme templates, the custom label order from the source template is applied to the current theme only when the option to Merge Individual categories is selected in the Merge a Template to a Theme dialog box and the template and current theme have the same number of categories.
