Help Index vector layers creating Creating a Vector Layer You can create four types of vector map layers-text, point, polyline, and polygon. Each layer can contain only one map feature type. You create vector map layers from spatial data provider (SDP) data sources; if you are creating point or text layers, you can also create them from points in a SQL database table that you have set up as an OLE DB data source. You can also use SQL database tables to link style information to the features in a layer. For example, you could link a layer of roads to a table that provides each road's name, length, and last date paved. You could then create a theme to display the data and quickly see which roads need paving the most.  For step-by-step instructions, choose Help Contents, click the Index tab, and look up "vector layers, creating." 156 | Chapter 9 Working with Map Layers
