You need to vectorise the objects in the maps. Create a new file/layer to put the vectors in. Do this by choosing:
File > New Table
Add to Current Mapper, which means that the new layer opens in an existing window and adopts the projection of that image. After
Create has been chosen we need at least one field called
ID. Set the datatype, Type, to Integer. After
Create give the file/layer a filename.
Layer Control by choosing
Map > Layer Control
A list of the layers open in MapInfo is shown. To be able to add, modify or to remove objects from the new layer it has to be editable. Make sure that the icon with a paper and pencil by the new layer is shown in colors. If the icon is grey, click on it to activate.
Create points, polylines and polygons depending on what you are vectorising. For this you use the
Drawing Toolbar (Dr).
Remember to save during the work.
