|Easy Tip: Simple map annotation – how to add circles, text and other highlights to your map
||MapInfo Pro includes a special Cosmetic layer in your map window. You can use this layer to draw circles, polygons, rectangles or make other annotations to your map In this article, we’ll show you how. It is pretty easy!
The info in this article pertains to all versions of MapInfo Pro.
The Cosmetic Layer
All map windows have a Cosmetic layer. This layer has many purposes and is occasionally used by MapInfo Pro itself. For example, if you use the Find command the symbol used to mark the found location is placed on the Cosmetic layer.
The Cosmetic layer is the topmost layer in the Map window.
The first step is the Cosmetic layer must be made editable. There are two easy ways to do that depicted in the screen shot below.

Once you have an editable layer, you can use the drawing tools to add points, lines, polygons, rectangles, circles, ellipses and more to your map.
In the map above, a rectangle has been drawn around the Docklands area of Dublin.
- In the ribbon interface (used by the 64 bit versions) the drawing tools are in the Insert gallery on the Spatial tab. See the screen shot above.
- In the 32 bit interface, the drawing tools are on the Drawing toolbar. If the Drawing tool bar is not visible, click on the Options menu and choose Toolbars. You have the option here to turn it on.
Editing an object after you have drawn it
After you have drawn an object, you may want to edit it. This could be to change the color/style or to move, resize or reshape it. There are a few different techniques you will want to know about.
The tutorial videos mentioned below will provide more detail on reshaping objects.
- To change the color or style, take the Select tool and double-click the object. A dialog box will appear. Click the Style button to choose a new style.
- To move an object you can click and drag it.
- To resize or shape rectangles and ellipses/circles, click on the object once to select it. You will see edit handles around the object.
- To reshape polygons or polylines is a little different.
In the 64 bit version ribbon interface, select the polygon or polyline. Right click in the map to access the mini-toolbar and choose the Reshape button. You are now able to select, move or delete each of the nodes individually.
In the 32 bit version, select the polygon or polyline. On the Drawing toolbar, click the Reshape button. You are now able to select, move or delete each of the nodes individually.
In both of the above cases there is also an Add Node button you can use to add additional nodes.
More information on Drawing and Editing objects
The MapInfo YouTube channel includes three videos on Drawing and Editing objects in MapInfo Pro. These were created using the older 32 bit interface but the principles and concepts remain the same in the new ribbon interface. You will find the functionality on the Spatial tab in the 64 bit version and in the Mini-toolbar, as mentioned above.
